Good Box

Great box does well with my subs would buy again

Heavy Duty!

I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

good box

I bought this box for 2 12" kicker cvx subs 750 watts a piece its a great closed box for them especially stuffed 1/4 with pillow stuffing.. looks real good to.. quick shipping

good value

product worked for my new hifonics subs. that will be a winter system for my ride so i don't have to keep my main subs in all year round. i really like it mostly because its has black carpeting.

The Box that Rocks

Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

Keeps blowing me away more and more!

This sub just keeps hitting harder and lower! I'm amazed and blown away! I was underwhelmed for a while there because I realized that I actually killed my previous sub by sending a very strong and very clipped signal to it by having the gain set too high for my head unit's preamp voltage. To reach the ~250W RMS the amp is rated for with my head unit, I need the gain knob LESS than half way up. Any more than that and it starts distorting, and this is not because of the sub but because I'M SENDING A CLIPPED SIGNAL FROM MY AMP. I feel like I've officially made that step from n00b to experienced installer. I had read all the instructions and guides before and never understood what they meant by matching the head unit's preamp voltage. Now I do and I know how not to kill a sub (and/or amp, for that matter).

Anyway, I had never broken in a sub and this sub is STILL blowing me away! It's hitting harder and it does better throughout the entire range. The lower notes (centered in the mid to high 30Hz range) I could barely feel at the start are now making the car have a slow, deep vibration when they hit (remember it's a sealed box). Being a 400W sub I feel like playing it full-blast at 250W RMS is good enough as 'breaking it in' and it is just finally beginning to impress me. It's hitting almost as hard as the Memphis sub that was getting a clipped signal with a few extra watts to compensate for my bass-trap trunk (thick leather seats, kills any bass trying to come from right behind you). Right now I'm keeping my rear seat's backrest down so I can feel the full effect of the sub.

I just can't wait to give it 400W. OMG. What a great sub. If 'you get what you pay for' is true 99% of the time, the HFX12D4 is the 1%, by far!

Amazing Enclosure, Even Better Price.

Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

great box

Very sturdy well built. Allows maximum bang. Great price under $60

Fast and easy great buy

I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.

solid sealed box!!!

Cant beat the price. But it is really very good box. I put two 12" hifonic,also bought from here, with a 2 channel 1000 watt amp.It really shook my rearview mirror in my '97 towncar. My brother loved it so we put it in his '92 prelude.Wow!!! You can hear him before you see him. Great buy!!!

Very powerful, ,,

Was hesitate to buy this,, glad I did hook up to a mofo 12, and re 10, I have 1/0 gauge from battery to cap then 4 gauge to amp,, I love it,, lights still go dim,, need extra battery it love power,, removed my crossfire xp1400d,, this is way better,,,,

Just purchased

I just bought this, and installed it in my 2000 accord. Don't be fooled by the price, this thing kicks. I hooked it up to my Pioneer GM-5500T amp putting out around 400 watts RMS. This sub sounds great so far.

Its a box

have kicker 12, they sound alright have some loose paneling in my car, so I'm having trouble getting the clarity I want. over all its a box and it works.

Nice sub

Sounds looks and is a great sub. Best for the money.

Hifonics HFX1204

These subwoofers really hit hard for the price. Probably one of the best I have ever bought. We'll see how long they last.

Great product

I've had these subs two of them hooked up to a crunch 1500 powerzone amp in a sealed box and they bump!! I've had them for two weeks and still working great! I had a previous set of subwoofers that hit great lows and I'd say that these subs don't hit great lows but they hit really crisp mids and highs :) I love them either way at great price I don't mind I'll probably get a third 12 that mainly hits great lows to even out :)

Good entry level sub

Good sub for moderate power systems. Doesn't like peak power tho. Went thro 2 of them with 750 watts max. If your going to dump some power into your system (+1000 wats), subs are not the place to save some $$.

awesome

Great Subs.Love Hifonics,you can never go wrong with them.And Sonic Electronix,I Salute on superb services.Thanks!

love these subs...

I bought two of these and I installed them in my Honda Civic. Have them wired at 4 ohms and they rock my little Honda. I don't even have them in a ported box. I've had them for a month. The only downside are the wiring terminals.

surprised

They actually sound good yet they're so inexpensive. I'm only using a 520 RMS amp and they bump, I can hear them from inside my house. A must if you're looking for some bang with out going broke.

Great box

I have this box with 2 kickers 12 in back of a Nissan altima and they soundgreat. Would recommend to anyone and would definitely buy again. Sonic electronix is the best

Great Speaker Replacements

I have some custom speaker enclosures built in 1975. The woofers have been replaced over the years due to the foam surround deteriorating. These have a more durable treated nitrile rubber that should last and slightly larger voice coil. The speakers sound better than the originals!

Great Box

I ordered this for 2 crunch gpv's about six months ago because I didn't have the tools to properly build my own box. After six months this box is still holding up and works perfect with my subs.

Awesome "BANG" for your buck

I am on a budget, like most of us. I needed a nice looking box for a reasonable price. For $52.00 you can't beat it.
I loaded my 2 12" Alpine TypeS subwoofers in it. Mounted my amp to the back and they are still going strong.

Sound quality > Rockford P3

Title says it all although rockfords not the best sub. Hifi is 1000% less than what its value is.

Hifonics

I bought these as a gift for my girfriends birthday. And they are very decent subwoofers. Thanks sonic!

bangn

Love it nice size for my subs still banging the same system

Solid Box

Ok so I bought this box because I wanted a quick sealed enclosure for my 2 JL W3's. The box is made pretty solid, true 3/4 MDF but the caulk job on the inside was kind of off but that's nitpicking. Haha after 3 weeks though of pushing my W3s the top of the box is leaking air. So not the best made but definitely a good pre fab and pretty cheap. Can't really complain. It is nailed together tho so yea..

Great

Good pounding subs for a great price one of the best subs I have had for a great price.

It's a box without a hole

Solid sealed enclosure. Two of them barely fit in the back of my 02 Focus SVT 3 door. The binding posts are cheap, I tightened them as I would other posts but one out of eight wouldn't tighten because the thread tolerance is poor and it acts like its stripped, I can get some pressure on the wire but I worry it will come loose. Probably worth spending a little more money on a better enclosure but it works fine if you're on a budget.

extremely impressed

i bought a set of these to replace some blown woofers in my house cabinets. of course after reading reviews i was curious since a lot of people have great things to say. i'm running mine in some older sear's fisher cabinets with decent crossovers ( not sure on specs ) off of a technics 5.1/stereo and in stereo mode i get about 150 watts per channel.

first you have to rip the plastic magnet cover off the back cause i could tell it was going to rattle just tapping on it. i wouldnt compare these to my L5's in my 7 cube ported box, but wow they sound amazing! my wife was amazed, and my brother in law who thinks he's an audio engineer was thoroughly impressed. i can't speak for the sound in a car. if i had them in a car i wouldnt feed the pair more than 1000 watts at most since they sound so good at lower power. if you are reading this i would say do it. buy one or 2 or what ever cause they sound good and only cost 35 bucks. absolutely perfect for house stereo woofer replacement. i gave it a lower ease of use score since you have to rip the stupid plastic cover off right away

very good sub box

The box is very good at 1.25 cubic feet. I'm running 2 12's with 800 watts rms and it hasn't shattered. Wish it was 1.35 cubic to accommodate for subwoofer basket displacement but it still makes makes subs hit ridiculously hard. Polyfill helps make the box seem bigger due to mechanics and the "Q" point. I really couldn't be happier!

Great Value!

I ordered this item for my grandson and he loves it.

Good value, good quality

Bought the MDFD12 for my son. Installing the subwoofers was very easy and the enclosure looks great. Highly recommend.

Cheap kit that did it's job

Inexpensive kit that works great for the 300 watt amp I'm running.

good box

It is a good prefab sealed box. I looks good and is functional.

good box cheap but good

this box is deferentially cheap but i put my 2 kicker comp 12's in there makes the sound good but i am thinking of getting a ported box soon, box is made with good material and i like it have it wired down to 2 ohms its sound good

no words

I've been a car system fan for many years and had alot of setups. These Hifonics Subs are more than you can ever expect from a low priced subwoofer like this one. If you are looking for a setup of two or more speakers these are the best. Great looking, powerful, CHEAP(money wise) and built to last. I have 3 of them and let me tell you they hit so hard my ears ring. Oh yea one more thing Sonic Electronix - a super glue should come with these subs cuz my rear view mirror fell right off. :)) That should tell you (buyers) that these product is worth of money. Thanks for reading this hope I helped.

Belva MDFD12

Belva mdfd12 12" box is good quality and good affordable price really good size an make my subwoofer sound amazing... 5 star

WOW Great Quality

I purchaced your Dual 12" sealed sub enclosure and added two Alpine R's and fosgate 1000w amp and WOW does not even come close, it Rocks. The quality of the box is really really impresive. The carpet in not the junk material I've seen in my other buddies combo's.
When you buy this box you know it will deliver and last a long time.... Sonic, keep up the good work!

Dual 12" 3/4" MDF Sealed Subwoofer Enclosure

If you are looking for a quality made box this is it !! I was very impressed with this box the moment I opened it.

The WOW factor was at least a 10.5 on the 1 to 10 scale. I WILL BUY AGAIN .

great product

I bought these to replace the blown subs in my daughters jeep. Great sound! These speakers really have great responce. Great value. Highly reccomend.

quality product

This enclosure is a well built enclosure for sq applications. I purchaced to house 2 CV vmax 122 drivers and the sound quality was almost rubbery? not tinny, never a crackle....fluid almost..... call it a well dampened sound with minimal distortion. just clean bass all the way into the 20s. made sounds i diddnt know existed. if you dont care how your music sounds and just looking for loud, look elsewhere. my only complaint, 11" cutout is too small for the vmax and the black carpet is difficult to follow a line with the router.

Great Sound!

i have 2- 12 inch Memphis audio 15-M3124D's in this box each putting out 2000 watts max hooked up to a MA audio HK10KA amp rated at 10,000 watts max. i have the subs bridged and it has way too much power going to them but the box still stands up. i would recommend that when you install your subs that you put some sort of foam stripping underneath the lip so when you screw it down you wont have and leaks at all.

Sleak, Sexy, Soundiful!

Its cheap, in price. Yeah, we see that. But let your worries go to rest, this is a GREAT BOX. Its well made, and put together great. Although they did use nails instead of screws, if you know what your doing, it won't slow you down. I have 2 12" Kickers in this baby, and pounds like a mofo.

Get this box. You won't be disappointed.

Best box for the price.

Not Cheap Subs!

These subs may be priced very low, but they kick VERY hard. Almost as good as my friend's Kickers. Of course it's not broken in yet so, I think it can hit harder than the Kickers pretty soon. Bought 2 of these, maxxlink amp wiring kit ($29.99 here), Autotek 1000.2 amp, and a Ground Shaker box ($59.99)! All with $200! Cheap doesn't mean bad. Get a good amp, wires, and box and you're good to go! Trust me, these will not disappoint!

good box

I bought this box to house two Pioneer TS-W309D2 subs. Box has a solid construction. I could not feel any air coming from the seams.

AMAZING!!!

I purchased this sub not knowing much about it, but I have it hooked up to my Hifonics 1000d at 2 ohms in a ported box and it KNOCKS!, the bass is so crisp and clear, I really was blown away. Most people think I have a much larger sub. Great job Hifonics! If you are on a tight budget, do not hesitate to buy this sub.

GREAY BUY!

I put 2 P3 dual voice 12's in this box and they sound awesome .. cant beat the price.. the quality is there

Awesome.

First time buying, skeptical at first but like all the other reviews said i'm extremely happy. Running it at 4 ohm about 100 watts above rms and its great low and high.

Its the best bang for your buck

The hifonics hfx12D4 is the best subwoofer on the market if your on a budget, yes the price may scare you, you say well with the sub that cheap how could it possibly be true that it sounds to good, well take it from me, i was very unsure of the purchase i made with this sub, i strictly went off of reviews, however, this subwoofer i my home theater sub, it hits. i owned 2 alpine type R 12s, so believe me i know what it means when a subwoofer hits. but the cold hard truth is, this sub is amazing the quality is so precise you cant help but to be cautious. BUY THIS SUBWOOFER YOU WILL NOT REGRET IT!!!

Great box

Runs 2 Rockford Punchs in and no air leaks and bass is clear as hell. Any 12 would sound great in this box, would buy again if it ever goes bad.

Belva BAK82BL (Blue) Review

Overall this was a pretty good kit for the money. The one downside was I was missing the following and had to go out and buy these to finish my install.
One black rubber firewall grommet
One 8 Gauge Blue chrome plated ring terminals
One 8 Gauge Black chrome plated ring terminal
Three 18 Gauge Blue Spade terminal
Two 18 Gauge Black Spade terminal
One 18 Gauge Red butt connector
Ten 4" Black zip ties

great with one easy fixable flaw

because of the design or the cage. the plastic cage rattles against the metal right below it. at first i had thought i had messed up my friends subs. then i realized because of the design of the cage it made it rattle. its a VERY easy fix. just go to your local hardware store and get some all purpose silicone or caulk and put it right underneath the plastic cage inbetween the plastic and the metal. let it dry. hook up your subs. problem solved! these are great subs. for the price of the subs i think its worth spending an extra 5$ and putting silicone on it.

one of my FAVORITE subs. they hit NICE AND HARD. i would definitely recommend

Good product

Built very sturdy except for the terminals. Its easy to switch those out though so no complaints. Thanks Sonic!

A little trouble at first...

The whole was no the size it said it was. I happen to be a part-time handy man so I had a circular sander and was able to make the whoel bigger. Took about an extra 20 mins of work to mount the subs, but overall everythign worked out. No complaints about box. It is doing it's thing!

No complaints

Good amp kit for the price. Not sure if it is true 8 gauge but at this price can't complain. Plus it is everything you need

Worked great for the system I installed. It came with everything to complete the project. Sonic has great service and fast shipping.

HFX12D4

I am running 1 12" HFX12D4 and this product is in a sealed 1.75 cubic ft. sealed box on a DS18 15001 monoblock amp, and I am impressed! I spent right at $100.00 for the whole set-up including buiilding my own box and installation. I think I got over so far.

Good sub

Ordered to replace a MB Quart. Doesnt hit as hard. Sounds very full. Have it in a 1. Cut ft box it is to small. Think that could be the problem but it sounds good enough. Using Kenwood exalon single channel class D bass amp. @ ~350 watts @ 2 ohms. Could turn the amp louder but my highs are from the Jvc deck 22x4 rms

YEAH

these speakers are amazing and the price is even better. I bought two and thought they would so pretty okay since the price was so cheap but these things rattled the streets when I went to pc this and everytime I pull up at my house the walls rattle. GREAT SPEAKERS A MUST BUY!

DO NOT BUY!!!!!

Bought 2 of these and both blew out almost a month in.... Put them in my Maxima in a seal box with a mmats 250 amp. These woofers are junk!!!! Replaced them with 2 fosgates that cost a few more dollars and it was well worth it.... No more headaches.......

Cheap price! good quality!

Great deal!... bumping just as hard as some 130$ subs. Embarassing to see these overpriced brands like kicker and pioneer get thought of as the best when these "not so famous" brands throw out better deals with better quality. I have just one of these in a sealed box and it even moves my rear view mirror a bit. For the price you cant go wrong by ordering this.

good cheap starter box

i bought this box about a year ago for 2 of my infinity reference 1260w subwoofers. I have two more in a ported box. im pushing 350w to all 4 and I have to say I like this box more than the ported. you feel it more in the sealed box but lose a little on the db's but its worth it. the box is sturdy and hasn't showed wear a bit. its tuned in the lower 40's so you wont get stupid low with it but can get loud. I would recommend it to anyone on a budget or to lazy to build their own box. it comes with polyfill which is a bonus, the terminals on the back need calked but that's with about any box you buy. overall I like it and would buy again if I had to.

Hifonics HFX12D4

At first i wasn't so sure if ithese subs were good or not but after buying 3 and hooking them up to a MA Audio 1800 watt amplifier i couldnt be happier, just one of them makes everything in my chevy suburban shake and the bass is so clear if in the right box buy i would recommend these to anyone who is looking for good bass and not wanting to spend that much money!

Cheap Nice Subs

Man, let me tell you. These subs sound good. I have 2, in a ported box. Hooked up to a Boss audio 2800.1,turned up half way. It's jammimg, just the way i like it. Nice sub for a low pice. Get some.

soso box!

Nice and built! really small box, has nice and deep sound... but the 12in kicker crvs need more space I think

Great deal

Worked great for a 240 watt amp powering 4 6x9's in a custom built enclosure

By Anonymous on October 31, 2019 Verified purchase

great product

Could not believe the sound quality of this sub for the price.It is amazing what it sounds like for the price.

Great box

Great box for the price and it can fit in any trunk.

AMP. KIT

VERY GOOD QUILTY PRODUCT AND HAD ENOUGH WIRE FOR PROJECT

Not worth it.

This wiring kit isn't worth your money. Just buy a decent one for $50 than wasting your time with this piece of crap.

Kalamazoo mi

Not bad for the price. I have them in a sealed box being pushed by 1500watt Rockford fosgate punch.passive equalizer on sub. They bump.sound okay. Not like mtx terminators, but good bass for price.im just use to serious sounds. Grand prix hold good sound anyway.the bass is not deep enough even tough I can see everything outside the car shaking.

ok subs

i have these subs on a 2800 watt boss amp. 2 of them in a ported box. they sound good for the amount of money they cost. i fried them both in about 2 months. my next subs going to be some kickers cvr.

Great sub for the price

I got 2 of these and was surprised with what I got for under forty bucks each, they sound great, and look decent, however as some other people have stated, the plastic cover on the bottom is really annoying. I'd recommend using rubber cement or sealant to keep the plastic piece from rattling on the basket

great!!!!!

was just the right amount of space i needed for the 12's

ok so far

Installed this weekend, I did add a couple pounds of "pillow stuffing" since the box was a tad smaller then what I needed. I have noticed some flex already but im not suprised with the subs that are in it. I will add triangle shaped gussets and some "trim screw" to try and hold things together.

A sheet of real MDF (not the cheap underlayment) is $32, carpet and glue around $15 so for what they want for this its a good deal that just needs some minor tweaks.

Kick a**

The sub box was really good.

Okay

The box is leaking now. But the price and design was worth it all in all; it's just due to be resealed.

Pounds

For the cost you can't go wrong. On Rockford 1200.1, but did not like the wire terminals.

Perfect

Not much else to say besides great product. Shipped in only 3 days, and the pre-done polyfill is a great touch. My only comlaint would be that my car smelled like glue for a few days after I put this box in, but that's just nit-picking. Will definitely order boxes from Sonic in the future!

Cheap Price = Cheap Sub

I bought one of these subs just because I already had a ported box that fell within the recommended enclosure requirements. 1.8 cu ft tuned to 35 hz. First of all, the sub looks good from the front. the rear looks kinda cheezy. Its lightweight. OK construction. Installed in box. Noticed a rattling sound just moving box around on shop floor. Turns out to be the magnet cover. Tried it anyways. Powered it with a PPI Sedona 550.1 which should be perfect for this sub's rating.

The rattling sound got way loud. Immediately removed sub from enclosure and ripped the magnet cover off. That helped with the funky noise.

The sound output of this sub is pretty good for rock. If the box is tuned say around 40 hz, it should slam pretty good for the price. However, when the lows kick in, this sub falls off BAD!!!! Not good for Rap or Hip Hop. Sounded like it wasnt getting enough power, but I know it was.

All in all, not bad for the price, but not good enough to warrant purchasing again. Not really worth the time and effort to install these subs. Just a cheap experiment for me.

Sub Enclosure Review

Perfect size to fit my Infinity subs. Wish it came with mounting feet but can't ask for everything. Quality is legit for the price. Just your average rectangular box. Fit in the trunk of my 240sx which is pretty small.

Nice cabling

Product performs as advertised. Came with most of necessary hardware

pretty good for the price

I bought 4 of these. One: to replace a sub that I blew. 2: as an experiment to see how well these subs actually are. $110 for all of them, why not? Ill call these subs EXTREME BUDGET SUBS. Baskets are plastic chrome. I have them in a 4-12's prefab separate sealed chambers. I have all each pair hooked up in series/parallel for a final 2ohm load on a RE Audio ZTX 5000.1 amp. According to my amp specs, at 2ohms im getting 1700 watts rms. Using my DMM and OHMS LAW CALCULATOR, I set the voltage so my amp is only pushing out 1600 watts rms. After 2-1/2 weeks of being easy on them to break them in some, meaning keeping volume around 15-18 out of 35.I started pushing them HARD. Volume at 27-30. All 4 are loud as hell. my kids wont get in my car if I put volume at 30. Theyre older teens, NOT YOUNSTERS. My car is a 2007 ford focus 4 door. Playing DECAF/bass songs that have very low notes I dont recommend for ling periods if time. These things heat up quite a bit trying to keep up and I have smelled the voice coils a couple of times. Maybe because I only took it easy on them for 2weeks. I would not recommend putting more that the rms rating through them. ALL IN ALL....im impressed with them for the price. My review is based on the 1 month that ive had them so far and for the price.

Great price

My friends are happy, and that's what makes me happy.

Great bucks for your Bang.

Great subwoofers for the cost cant beat it. sounds good, hits hard just all around good quality.

Great Box

Subs fit great and the construction was sound. Thanks Sonic!

Yeah.

I got two of these and they're pretty good for the price. I've had them for over a week now and they do hit pretty hard. I have them hooked up to a cheap nitro amp and it's powering them but for the kind of music I listen to these subs can't really handle it. They're great for country and rock music but not songs with deep low bass.

Great subs

I have these in a 1.75 cubic feet per chamber ported and let me just say wow. These are cheap and give lots of spl. I have two Rockford Fosgates and these hit harder for less then 1/3 of the price! Overall these are wonderful subwoofers.

Amazing Value

I have 3 of these in a slot ported ebay box in my game den being powered via a Behringer EP2500 amp wired parallel / series for a final load of 6-ohms (meter reads closer to 5-ohms which is a plus). They only have a few hours on them so they are a little bit stiff still. They are the best value out there as far as I am concerned and Sonic got them to me within a weeks time well packaged and un-damaged. Although not a typical installation, they MORE than fill a 1,000sq.ft. room with authority and will do the same in a car. I am giving them about 1,400RMS and they take it all. My ONLY complaint is the connection terminals (spade style). A little bit of soldering is no big deal though, especially for the price point these are at. Very satisfied and would highly recommend them to anyone.

GET WHAT YOU PAY FOR!!

This box looked great and felt very durable. My subwoofers wouldnt fit at first so I had to do some shaving, NO PROB. It sounded good for awhile and I loved it. After about two weeks, it lost its sound, went to check out the problem the whole front of the box had almost came off, Box was sealed very well, too bad they used nails instead of screws, would have been a very good box.

Nice Box

This box is pretty clean...nice black fabric, enough to hold the subs and gives them enough air to makes the subs bump and bump and bump and bump! Good buy at an unbeatable price. Awesome.

Great Value!

Its a great wiring kit for the money. You cant beat it. Wires are nice and flexible, unlike other cheap wire thats stiff. Id buy again.

By Andrew on September 15, 2015 Verified purchase

Great box

This is a great box. I prefer ported but my trunk is too small for it so I had to go with sealed. I'm still happy though. This had the perfect size for my 12s. Also the measurements are a little off. The box is a little bigger that the description said.

Impressed X100

I thought being broke would suck, but after i bought these subs life wasn't that bad, I drive to my campus rocking the whole parking lot! I've never been so impressed with a product until I've invest my money in these things. If you're on a budget and you want loud reliability go ahead and click that purchase button because you wont be disappointed.

Better than previous model

I have 2 of the older HFi12D4 in one box and two of the HFX12D4 in another, both in parallel, so they took same exact power and the Hfi burned up at around 250W RMS (1000 divide by 4) while these remained unaffected.

They sound great, and even though the HFi12D4 looked prettier with the chrome on the edge, and the nice pressure terminals. This one is better because this HFX12D4 actually outperforms them very slightly AND take more power so they won't blow on you at higher watts!

The HFX12D4 are supposed to replace those HFi12D4 anyway.

These woofers are a good alternative to the expensive competition woofers because they SOUND good and they are LIGHTER so the weight won't drag your car down, especially if you have a sporty car you want to keep weight at a minimal.

They're not as loud as the loudest, but they are great for lower power setups as they sound deep.

I would say they are as loud as any woofers around $100 and below price range, and have a nice bassy hit to them.

wow suprised

this is the best sub that u have ever owned. i just recently had rockfords and these pound wayy harder and they way cheaper. pros- decent size voice coil for a sub and gets all the lows. cons- would be nice if it had push terminals

great subwoofers!

I have two of these running off of a 1100watt amp and they sound great! After a while of bumping in your car the subwoofers will give you a headache!

good bang

I owned some of these in the past n was hesitant of buying but I got them cheap so I said what the hell so I put them in a 1.25 sealed box with 225 watts RMS each n they sounded really clean and pretty dam loud for low end subs jus give them sum decent power n hook them up rite and u wont b disappointed especially if ur on a budget or get Powerbass PS-12s there on this site, they sound good i have 3 of them in a triple sealed box

Great Subwoofers

Everything was going perfect with the two sub woofers i purchased. Great price & everything. But then someone stole my car & the woofers were in it. Anyways, they were GREAT while I had them.

Great

This is a great sub woofer box for the price it is heavy 41 pounds and it is sturdy. I have 2 12 kickers 600 rms 1500 peak and they sound great in this box hits lows and highs hard. I would say to any one buy it.

Okay Box

had to trim the 12" hole for my Sound stream PCO.12 subs they wouldn't fit at all. once I trimmed the MDF I love this box. they could have used spring term instead of screw though.

Good buy

I would buy this speaker again...Mounted up perfectly and sounds just fine...

yea they bang

i have four of these in a 01 cadillac dhs and my s### bangs just crazy rattels every in my car and anything near it i putt these with a brutus elite 2500 dealers only model im pushing it at 1700 watts at 2ohm wich is 425 watts per sub man some people cant even sit in my car . it is crazzy there great and for the price so what if you blow one buy another one and keep on bangin

Great price for this box, very reliable. I put 2 lanzar 15s in here and they sound great, would highly recommend buying this and not wasting more money on a more expensive box

great box

this box is light weight. its made strong and fits every sub ive ever used in it.

Just what I was looking for!

I purchased this to go in the trunk of my 1966 mustang. I purchased it after reading another review of an install in a mustang. It fit perfectly in the side of the trunk and did not take up a lot Space. Sounds great.

nephew

My nephew loved this product along with the Autotik amp and Kenwood subs for Christmas. I even upgraded my old amp with a 4000 watt PZX Crunch amp to keep up with my nephew and his system lol

nice & clean

I replaced my old box with this 1 & man what a difference. My old box was 11 years old & I didn't realize it was falling apart & with this new box I noticed an instant difference. Its a great box for the price, it holds firm & can handle the full pressure of 1100 RMS

I did have to spray a little adhesive inside for 1 part of the foam & terminals were screwed in & not exactly straight & I also had to poke holes in the foam for wires but these things are no problem. The box is awesome & I will by more in the future

Great Price Good Sub

Have had everything from W6,TypeR,Comps,CVR,IFINITY,VEGA IT,MTX 8500,ECLIPSE,RF P3,TypeS,TypeE,Coustic, W3,and more, got these ones on EBAY $48 pair and a Boss 1600/2 As I was unemployed and needed my bass fix on a broke man budget was a sceptic.I had them about 1/3 gain to break in at 2OHM. They have better than impressed me for price.Only issues as most people have said on here is crap terminals and plastic dust covers.I Put two in a Obcon labyrinth dual slot port box with 3/4 spacer for extra Cu.ft they Hit HARD. Almost better than CVR'S. EITHER remove or glue plastic basket and DON'T over power & take time break them in. I now have them mostly up on gain just trying to fine tune the bass on my Kenwood Excelon 397 is at -6 and they RUMBLE THE S*#@ out of my 2001 TAURUS. I order another pair so I can run a triple and at $75 for three it will out perform setups TRIPLE in cost. my deck cost more than subs/amp. If you Take time hook up right break em in and tune I have no doubt they will perform beyond expectation.Would probably be best uf have extra $$$ run RF 400/2,KICKER 400/2, Alpine Mrp 500,JL 360/2 OR 500/1(not slash), other wise a cheaper 1500-2000 watts monoblock or 2ch will match best for 2 of these. Watch EBAY AS WELL can get Boss/Power Acoustik/Planet Audio Etc. in that wattages around $60 and the other Namebrands Around $100. I just scored a power acoustik BAMF 2000/1D @ $93 to run three of these should push and not overpower giving a long life(longer than I will have them)

Excellent

Not only does it look cool, but it sounds great. Put it in a vented box from Sonic with correct recommended volume spec. I am powering it with an "old school" Hifonics "Odin" amp with 75 watts per channel. It produces "vulgar" bass......For that kind of performance, with relatively little wattage, it is very efficient. It is similar sounding to my Alpine single coil 12 inch. Without a scope, it is hard to tell which has lower frequency response.

Good bang for the buck

It's tough to build a box for the price you can buy one of these. They are solid. I haven't had any issues with mine.

Good Quality

I would definitely recommend this box to a friend, Nothing like a good old professionally made box, I love the material that they put in it, it really adds to the sound.

suprized

I looked at these subs for awhile now my cousin got one i hooked it to my 800 watt rms legacy amp no gain in a sealed 1.25 cube foot box and it hit just as hard and my 2 duals do in a bandpass i was amazed on how great it sounded. So i bought my self 2 today will be switching out the duals for these. Get these if you are tight on money they will hit harder then kickers if you know what you are doing.

Impressed!

I was impressed by what this sub can do its definatly worth the little price tag!! Also it being a dual 4 ohm voice coil sub is very nice!

Unbeilevable!

A real review.. This sub is amazing! it is built good and looks pretty cool. I have it powered by the kicker dx250.1. I am giving it about 280 rms and it sounds awesome! Hits the lows and mids like a monster but doesnt really hit the highs. Well worth over 100 bt only paid 38! If youre on a budget this is the way to go, you cant go wrong. I recommend it 100%

Must Have!!!!!

This is an awesome enclosure. The price is very competitive as well. I am running 2 Rockford Fosgate R2D2-12 and there is no distortion at all. It is a very tight, clear sound. I highly recommended for anyone looking for a high quality low cost setup.

holy shnikies

these two in a sealed box in a miata with 375 watts rms total input made the thing sound like the car was rattling to pieces. bought another box and put just one in there and even that is a bit much! very clear great value!!!!

Great Value!

I have two of these subs in my car and i am running an 1100 2ch amp into them and they are so loud i have a headache after like 1 min of bumbing. They also unleveled my trunk too.

Ok Buy.

I ordered this subwoofer for my friend to put in the back of his civic. The sub is just ok its neither good or bad it works as it should and sounds good, definitely does not shake the doors of his car, Good subwoofer for someone just getting into car audio.

good quality

I just bought four 12" subwoofers and they play exceptionally well and they hit real good for the price of them. If you want to get some speakers for a low price and good quality hifonics are the way to go.

Good Sub Box

I like it, I think the covering looked good but I ended up messing it up trying to screw something into the outside. Otherwise i liked the box, my subs hit good in it.

Worth every penny, and then some

Right out of the box and into another box, lol.
I have it hooked up to an alpine mrp-m500 amp with the gains corectly set then pulled back a little, as I want to have even amounts of bass in comparison to the other speakers. This sub sounds excellent, I know you get what you pay for but this is too good! The sub hits hard and clean and can handle the s*** I give it. I have the sub wired down to 2 ohms at 500watts, which is the happy max of my amp. It handles the max power without issue.
The only drawback is that poorly affixed cover on the magnet, some frequencies make it vibrate, but it can only be heard when my trunk is open and I have my volume past 70%. Solution? Tape wrap your favorite tape along the gap between the cover and the chassis of the speaker. Viola best speaker ever! You don't get this quality at this price anywhere else.

great value!

These are affordable and an awesome product! They sound great in our vehicle!

Great for the money!

I bought 2 of these to go in a ported box. They are currently under powered by about 150 watts or so, but they still hit pretty hard in the back of an 07 Aveo5. Would definitely recommend these to anyone looking for some pretty good bang for the money.
Only one small complaint though, One of the dust caps on the sub started to come off shortly after the break in. Fixed it with some thin compound hobby glue. Other than that I love em'. Also would have been nice to have some different terminals than the ones on there but no big.

ELW1214.2 BOX

Superb Box! Tight sounding bass, and best of all deep rumbling bass. Excellent for an audiophile like me.
Easy to install and use!

Great Value..

The reviews don't lie, these are great subs once you remove the flimsy back cover that rattles, put them in a 3.2 cu ft 4th order enclosure and it's a match made in heaven, they pound the ground..

Amazing, especially for the price

My life is littered with Subs of all sizes and brands. I've probably owned 20 different ones, and currently have 4 or 5 sitting on the shelf in the garage. To me, the mostly sound the same, and I've spent $30 to $500 on subs, and they still sound mostly the same. I always like Hifonics stuff, either old school, or newer (Maxxsonics) era, especially their bass equipment.

Built a box for a friend, and decided to try this sub. WOW, just WOW. A great solid sub in general, but for the price, HOLY COW. The thing just slams, and is responsive enough that it can be subtle too. And its not even broken in yet. Powered by a Hifonics Gladiator 1000W amp, the combo is simply awesome. I can't imagine there being a bass section that is better than this.

Now mind you, this is not built like a competition sub, with cast aluminum baskets, 30 pound magnets, and spiders made of space age materials, but it also cost 35 bucks.

You basically can't go wrong with this product. Anyone who complains about the Hifonics HFX12D4 just has expectations that are completely misaligned with reality. Its a bargain, it sounds amazing, it has terrific texture and can handle subtle, as well as earth shattering bass, and it even looks decent.

good value for an entry level sub

I think this sub is a good entry level sub with a great price...it does a decent job of producing bass frequencies providing its in the correct box.

wonderful addition

I have a 15 inch in my Yukon and wanted more db's to pound my chest. After reading many positive reviews about this sub, I decided to give it a chance. I purchased it with the 1truck12 box and added about 6oz of polyfill to the box. The sub does not come with push terminals but I do not mind. It looks good and is built surprisingly well for a $30 sub. I wired it to 2 ohms and have the whole circuit wired to 4 ohms. Boy oh boy! I feel it in my chest now! I have significantly deeper and louder bass! 2 or more of these sub's will shake your ride and make you smile. Thanks Sonic :)

good subs

I received these subwoofers last week. Have them hooked up to a planet audio 1500.1. The subs are nice, i just need more power. Next week I'm getting a boss Audio 3000 class d amp. Then I can beat them. I'll let you know how they sound next time. But, these are some good subwoofers. Buy them.

Recommened

I would recommend these not bad at all for the price $30 can beat that, but if your looking into being loud and rattle other cars these aren't your subs. These are nice for little setups to have some thump, so far I ordered 4 of them blew them within 10 minutes, but I have to say nice sound quality came from them, nothing in spl loudness range these came no where close.

Extremely good for such a low price

I have 2 of these in a sealed box, wired parallel/parallel to the HFi1500D at 1ohm, tuned to 780watts. These things slam for the price they are at. I was surprised! I now plan on using until I can get a chance to upgrade more.

Hits Hard Enough

I have one of these in a sealed box and it's getting 600 watts RMS. It hits the lows really good, sometimes the highs hit hard, but it could be a little cleaner. In my single cab truck it fills the cab with nice clean bass. Just the highs could be better. Haven't tuned it properly cause I havent had the time, just wanted the system in quick for a long trip. I'm upgrading to two 15's so then I'll take the time to tune it. But even for how it is quickly tuned it sounds great.

GOOD SUBS

These subs do pretty good. Gives a nice sound.

Not bad

For entry level subs they are very surprising, good bass response. Have them on a 400.1 amp so I'm powering them by the recommended rms power and they sound great.

Belva 2 12" sealed enclosure with my 2 12" Infinity Kappas

Great box, holes were perfect sized and nice mounting depth! My triple voice coil Infinity Kappas with the 1600w amp SLAMS!!!!

DIY Sub

I owned the HFI (previous model) and loved it. This new version is cheaper... and I can tell. I installed one and it buzzed like crazy. Ordered a second one... also buzzed like crazy. It's the plastic cover on the back. Totally pointless. Pry the cover off to fix the buzzing. Then you have a non-buzzing, crappy subwoofer.

Definitely worth the money!

Just got two of these this week. I was looking for good cheap subs, and Hifonics always seems to be there. They hit hard with the autotek atx1600.2, but i think once i break them in im going for something bigger. Owned some older hifonics subs a while back and they lasted forever until i sold them. Not the best subs in the world of course, but if you are on a budget go ahead don't be scared, they are definitely worth the money and sound much more expensive.

these subs are a great buy for the price

I have 4 of these subs in a 10.6 cubic ft ported box tuned to 32 Hz powered by a NXD5500 and they hit hard for being a cheap end sub. They have an awesome look to them, but Hifonics could have made a better basket, and changed the terminals. Overall, it is a great buy.

Good for the price

This sub sounds really good for the price. It hits pretty good.

great subwoffer

i own 2 of them for 2 years huckd up to 2000 watt amp briged 800 watts going to them and they pound worth the money recomend them

Good Budget Subs

Got a pair of these to hold me over until I can afford something bigger/better, but these performed beyond my expectation. They sound great out of my slot-ported box, the only downside is they will overheat if you let them, but with a slot-ported box it is very easy to smell the heat, and turn them down. Longtime Hifonics fan, great subs for such a low price!

Great 12's Box

This box is designed well. It is assembled, sealed, and carpeted very well. Speaker terminals are nice inside and out. Couldnt be any happier with this enclosure. Will use box with various subs.

Excellent!

Cheap and effective! This is truly one of the best boxes that i have bought for the price it is. Sounds great and made very well!

best box 4 the buck

Don't let the skimpy price fool you. This box is made very well and it's ready to go. The joints are already caulked and glued - so there is nothing more to do than mount you speaker.

It's not MDF(medium density fiberboard) like all the others, it is made from HDF; high density fiberboard. HDF boxes are typically stronger, stiffer, and lighter than MDF enclosures. The box does not require any additional bracing because of its density. It has a high an undetectable high frequency resonance and doesn't color the sound of your bass with unwanted buzzing or flexing. The HDF box is lighter than MDF because it has smaller fibers that when pressed and heated require less glue and resin to bind the fibers together.

The speaker terminals are screw type gold plated binding posts that will hold 12 g speaker wire easily. They screw into the enclosure for added strength and a tighter seal.

Just make sure that you do your math and pick the right sub for the cubic feet and stuff with poly fiber fill.

Awesome

Bought this for some 12" audiobahhn subs I bought 2 years ago still brand new in the box and hooked everything up in my 91 civic sedan to my
Hifonics BRX2000.1D Brutus Mono block and pure awesomeness. The box makes these subs slam. Highly recommend this box

Impressed

I got these a month ago and I'm very impressed with them for being cheap subs. That sound really good and hit pretty hard. Can't complain about these subs.

nice item! !

I really love it!! how it sounds fantastic can't complain great value

very impressed!!

This is a great value for a good tight bass 12" sub. I own a 97 lincoln town car. I bought two of these subs and a Belva lined box. They really hit hard!!!! I don't do sound competitions, I have hard hitting street cars. I plan on ordering two more.

no complaints

i got these for 35 a piece and they rock...i have 2 of them in my wifes car wired at 1ohm on a boss 2500 mono amp..and these hit so hard..if you are wondering about getting them based on the price if they are cheap...DONT..get them you will not be disappointed they are worth double the price..

hittin hard

These subs it hard.I was surprise how hard these subs hit. Buy these subs put in a ported or sealed box , hook them up and watch how hard they hit. You can't beat the price. Get this sub.

bosinas

Muy buen bajeo muy buenas y baratas buen color diseno y la marca ni se diga.

Amazed

I have this sub in a ported box about 1.7c ft per sub and they sound great for the price, ive had rockford, diamonds, american bass, memphis, mtx, XXX, and a few others and im not saying these are better than those but price to what you get these are worth it they sound really good but im not pushing them because they can't take the power lol. For someone just looking for bass here is a good choice.

Extremely well built

Insanely well built box.

Carpet job is top notch, Good quality carpet stretched perfectly over the box. All joints are glued and caulked well. theres no need for extra bracing here but you may add some 2x4's to reduce the airspace if needed. The gold push terminals are well sealed in place.

Hits low and hard with all sub's I've thrown at it (JL Audio 12W04's, Rockford Fosgate P312D4's, Kicker CVX12's and finally Alpine SWX-1242D's)

Don't be afraid of the price. It's a perfect price for a box of this caliber. Would recommend it to anyone.

Tuff Stuff

Nice heavy, good sounding box. I would reccomend putting some polyfil to "cushion" the backfire of the subwoofer, really helps w/any sealed box and totally makes a valuable difference considering it only costs about 5-10$ more. The box itself is well sealed and well made, the connectors on the inside and out are really easy to use and once connected your wires will stay put.

Good Product Good Box

This box is great for the low! I don't have nothing bad to say about this product.... The sound quality is awesome with this sealed box.

By alan on June 18, 2015 Verified purchase

great budget speakers

By kris on April 26, 2015 Verified purchase

BIG BANG FOR A SMALL PRICE

i bought 2 of them no lie they hit hard i have then in a box thats .27 too big but none the less they are still hitting hard if your on a budget and dont want to go over it then these subs will get the job done

pretty good subs

I bought these because I wanted to try a new brand. Never owned Hifonics before. I bought two of these and a Hifonics 1000d amp to put in my 98 GMC Sierra ext cab. I haul my kids around sometimes and had to buy a dual 12" Pro downfire box. I also bought 1" spacers to get a little less depth, and stuffed it with polyfill for more airspace. I still think the box is to small for these subs. The set up sounds pretty good, but obviously not as loud as the 3 MA Audio 12"s in a triple box I had to sell. That thing was a beast. Anyway, not bad for the money. I will say, try and get better terminals for the subs, the stock ones are crap.

hi

I buy 6 of them and i put with planet audio mono 1ch 4000w on my town car 95 and i blow my trunk. I really recommended to anyone.

Good Subs For The Price

I bought these about 6 months ago at a retail store, i was scared at first because of the flimsy packaging. Anyhow, these subs run at about 400w rms each, i have two of them. I am running them at about 350w each because of the amp i have and these babies hit hard! They are a good buy if you are just starting out with audio electronics or simply if you just want a cheap reliable product! :p

Best Bang for the Buck

These subs BEAT! I mean wow, its amazing how cheap these subs are in price compared to the sound they are able to produce. I purchased these subs awhile back as I was waiting to build a box. BUILDING THE BOX is the KEY to making your subwoofer perform at its best. Get the right box and a good amp and these subs will not disappoint.

Take the chance and you won't be sorry

I purchased 2 of these subs, and when i unboxed the subs, i noticed good construction and impedance was correct from the factory on both VC, cone felt pretty rigid, and the overall design was good. I wired the subs to 4 ohms using the supplied handbook with the subs...oh and by the way, if anyone from Maxxsonics happens to read this...please for the sake of humanity just put regular push terminals on the subwoofers. Spade style connectors work but are very annoying to say the least!! In any case, i put the two subs in a ported box i bought off of Sonics, the dual ported box, sounds great, very pleased for how low my budget was of less than $250, i have the 2 Hifonics subs running off of an 1800 watt max Boss Audio Onyx series Amp (Monoblock), 4 ohms-900watts roughly to both combined. I still need to find the right tuning on the amp to get the best sound but overall, I am very happy with everything and I would definitly recommend these subwoofers to anyone looking to get a GOOD not amazing sound from a small pocket, hope this helps!!!

Hooked on Hifonics? Count me in!

I just replaced a Memphis Power Reference subwoofer with this one. If you don't know about Memphis, look them up, they make quality hard-hitting subs. Well this Hifonics HFX12D4 sounds just as good and may actually even hit harder. It's only getting maybe 200W RMS if that from my 250W RMS amp that's turned up just a notch over half way. It hits very hard, it's not broken in, and it's missing out on 50w+ RMS that I will be giving it after break-in period is over. I can't wait to hear how hard it sounds when I can give it real power. I have it in a generic 1.25 Cu Ft sealed box, it's being powered by a Directed 250d amplifier, and I have it set to hit up to around 125Hz and it handles the high notes just fine. A more than formidable replacement for the old Memphis PR sub that I was running. Hifonics was the right choice.

let me see

I bought 3 of these (under $100) and put them in my car on a SoundStream Rubicon 2500.1d wired in series/parallel and im starting the break in now for the next few weeks before i put the amp to work on these subs. Looks good mounted, don't like the input terminals on the subs very rinky. And the plastic dust cap is just for looks. But it doesn't take away from the sound they produce now. But the shake i feel in my car just tuning the amp: wow. Had 2 cerwin vegas and they didnt shake me outside the car. But these will work till i can upgrade again and for the price buy as many as you want but keep the 4 ohm at the sub, it will burn it out if on a lower independence.

best for the price

I have 2 of these hifonics wired together to a 4ohm load briged to a hifonic zeus 500.2 and it hits hard. it also sounds very good. this is the very best for the price, especially if you are getting more than one.

this is a solid box

when i bought this box i wasnt really expecting much, because of the price an all but when i put my rockford fosgates's in it, it did sound great, and let me tell you im gettin 2 12 alpine type r next and im for sure going to be getting this box again.

so dont let the price scare you trust me you wont be disappointed

Good Box

I have this box with two hifonics subs, hooked up too a hifonics 1600 wat amp. Its a very good box and hits really good. Would approve to anyone.

Great Box

This is a well built box. Great quality carpet. If you want a good box without paying high prices this is perfect.

Your basic sealed box

Great box. Quality carpet job, all seams sealed correctly and well, and the terminals are strong and functional. Perfect basic box to make two twelve's hit perfectly. Just remember this is a sealed box, so it will have a differnet sound than that of a ported or bandpass box, but if u want a tighter hitting bass, this box if perfect.

Poor quality

I had ordered a Kicker pk8 amplifier wiring kit and these were part of a package that only Sonic had offered. To put it shortly, one of the jacks was grounding out when I plugged it all the way in the RCA jacks in the headunit. It was causing a lot of doubts in the equipment in my system, but I got down to the root and these were the culprit. I contacted Sonic and they gladly replaced the with a set of StreetWire RCA's that worked just fine when I installed them. Thanks Sonic! But as far as these go, I wouldn't recommend them. Spend a little more and get some better ones.

Take the good with the bad

As the other reviews say, loud sub that makes decent bass for the money. Low end signs off (makes weird noise) so a subsonic filter would be handy with these subs. Bass drum kick hits hard for two twelves though. Quality leaves a bit to be desired as the terminal post on one was not attached right out of the box. Surround let go of the basket on one sub as well after about 10 hours. Nothing a zip tie and some cyanoacrylate glue didn't take care of. As said, for the price I guess you can't go wrong considering I've had similiar issues with high end subs before.

damn good buy

I orderd mine from eBay. All i have to say is wow. These things pound. I have them in a prefab box with a 820 watt spl amp in my 1993 blazer and these things really beat. I have all my bass and subwoofer gain on the deck turned down and they still hammer. Haven't even broke them in yet! A must buy for any budget system!!! Or anyone who wants beastin cheap bass!!! Good buy!!!

These woofers bang!

I purchased these woofers mainly because they were DVC and my previous woofers, JL audio's were not. I needed 3 so they were perfect and the right price. These speakers are the truth I have 3 bridged on a 1500 watt 2 autotek amp, purchased right off of sonic electronics. Even with the bass knob turned down and with the factory radio I have a rumble with the radio on anything past 5. I've only had them for 2 weeks so I cant speak on durability but reading the reviews helped me make my decision and I hope this review helps someone make theirs.

Best buy for the money!

Bought 2 cause they were cheap and this was by far my best decision yet. Running them off a 1600w 2 channel amp they get louder then most of the kid's several hundred dollar systems at school. I would recommend these to anyone, just make sure they are in the right sized box.

Easy, cheap price, great quality

I bought this box for some Rockford Fosgate P1's and I couldn't be happier. The box is solid and produces some really good sound in my Audi.

Good quality

I was very surprised with the quality of this box. It was well made for it being a prefab box. The polyfil definitely gives the bass a deeper sound.

Excellent!

I bought this for my husband for his birthday and he loves it!

1 month... still going

linked parrallel at 2ohms in a 1.9 cu ft per sub rt enterprises vented box $55 on the bay, pushed by a pyle pla 2378 amp 250 watts rms at 2 ohm ( from sonic) these subs really shake my kia soul . Magnets are not huge maybe 30 to 40 oz, not competition subs by any means but for cost conscious they thump. Save yourself some headaches and take a flat head screwdriver and pop the wack caps off the back. Held on by a dollop of glue on the back of the magnet. One of mine was already off upon arrival. I've got $200 total in the amp, subs and box and am very satisfied... included booklet has good info... on cu ft for both sealed an vented boxes plus several easy to understand wiring diagrams

good for the money

I used two of these in my car in a box that had .98 cuft per chamber. These sub's call for 1.5 cuft per sub. Needless to say these subs didn't hit very low with my setup. I guess it also didn't help that they only have 6.5mm of xmax. In my particular setup the lowest note they would hit proficiently was about 40hz, loudness topping out at about 44_45 hz frequencies. At these frequencies these sub's actually got pretty loud. Just as loud if not louder than any other budget sub's I've tried! Needless to say, these subs are definitely worth it for the money, don't expect super low bass but they will definitely get loud. Only thing I did not like about these subs were the bare flat terminals to hook them up, I guess that's what you get for a budget though.

REALLY GOOD DEAL!

I bought 1 12" HFX12D4 and a 400w amp for the back of my 78 bronco for some cheap bass and I must say that I am very impressed with this woofer! My sub hits every bit as hard as most guys lower end systems with 2 subs! This won't blow the glass out of your vehicle but for the price, you absolutely cannot beat it!

Great product

I recommend this product for its power and reliability.
Very good report quality price.

title

Great box well made great value enough said ten word review

great value

I would recommend sonic electronix to anyone the prices are right and the product's are great and another good thing is they ship fast...

Great RCA Cable

I used this with a 5 channel kenwood amp and a pioneer head unit. worked like it should.

Amazing deal for the price

Wow is all i could say. Got them from a local dealer in my town, pulled them out of the box, and started beating the crap outta them. Got them to add to 2 Kicker CVR 12's, and was a little skeptical at first. But as they started getting broken in, the more surprised I became with them. Seem to be handling the power quite well. Entire setup is powered by an MTX RFL 600rms, all getting the same power. Amazed at how well a $40 sub handles the power. I don't know what the RFL 600 is actually capable of, but it's pushing the CVR's and the HFX's to their limits. BUT, the only complaint I have about this sub is the dust cap, seems a little flimsy. But other than that, a rock solid sub ready for whatever you can throw at it. Will be buying again for my 8 12's setup that I plan on doing in my F-150.

Great subs!!!!

Well to start off I bought these subbs kinda on a whim because of there price and was more than pleased with what I have got. I would recomend these to anybody looking for a system that could beat kicker and stand with jl I have only found one problem with them and its my girlfriend has a hard time breathing so she doesn't like them as much as I do but they have handled everything I've thrown at them not to mention that there rated at 400 watts rms and I broke them in rather well by running them at about half for a month (hard I know but well worth it) now I'm running 500 watts rms through them on a daily basis

amazing for the price

For the price they are the best on the market I think there around $** now. These sub have and amazing sound and clarity for what it is but it can only handle about 500watts as a pair as I had them.but if your on a budget get them

robbie_d_355

I am little disappointed with the quality. It didn't produce bass with my Hifonics 500 watt amp and popped hard(not a bass hard) with my Kicker 300 watt amp. I eventually put the speakers in a real small box with an Old School Fultron ME50 amp and achieved mid bass at medium levels. It is what it is for the price. They will produce bass, just not clean, responsive, as a sub should to maintain a companies reputation.

Better than previous model

I have 2 of the older HFi12D4 in one box and two of the HFX12D4 in another, both in parallel so they took same exact power and the Hfi burned up after 6 months While these remained unaffected.

They sound great and even though the older model (HFi12D4) looked prettier with the the chrome on the edge, and the nice pressure terminals,
This one IS better because this HFX12D4 actually outperforms them very slightly AND take more power so they wont blow on you at higher watts!

These woofers are a good alternative to the expensive competition woofers because they have a good SOUND and they are LIGHTER so the weight wont drag your car down, especially if you have a sporty car you want to keep weight at a minimal.

They re not of course as loud as expensive comps,
but they still hit hard for lower power setups and they sound deep.

I would say they are as loud as woofers 2-3X their price,
but the key to most low cost woofers like these,
is to not overpower them .
So listen for their "hit" and back off your gain slightly from their,
for longer listening sessions .

great subs

i have these subs and they beat hard i have a 1000 watt autotek amp 2 channel. My co-worker like them.so buy these speakers, if you want good slap at a cheap price. thanks sonic eletronix .

Pretty Nice

I'll be straight forward I only bought these as a quick replacement after I blew my old 12s , good sub for the price well built looks decent and pretty light. I have it in a 2.0^cube ported box on around 400 true rms amp and its demanding more power. However, at 400 rms they seems like they are almost maxed out as far as I can see they are moving like crazy and the excursion is so violent the subwoofers look like theyre going to rip apart and i smell the coils getting hot at about 1/2 gain on the external gain knob I never back off of them until the amp cuts off..they draw alotta power surprisingly! They dont really get as low as other 12's I've had but I also was running a 900w rms Soundstream amp on them. I'll update once I throw my batteries back in the car for the amp and change to my Db Drive 1250. Im just not so confident that it can take a true 800 watts.

Good Product Good Sound

If any one is looking to get a subwoofer and you want something for the low with great sound. Get these! The reasons why I got these subwoofer because I'm a college student.... I'm not worry about the price. All I worry about is how much I want to spend.

I don't really care much about super loud system. I just want a good system with good sound quality. I've always have my bass on low while cruising down the beach or highway because I wear hearing aid. To be honest.... The sound quality is awesome! I don't regret getting these. I don't really care what other people think or say. This the best product I ever own. I'm looking forward to shop at sonic again in the future!

I used this kit to install an NVX Quick Bass 8" self-contained subwoofer system in my Ford F-250 SuperDuty. The wiring overall is a good quality for the price and the length of the kit gave me plenty of options as to where to mount it in my truck. For the $15 I paid, it did the job and the subwoofer sounds great. The kit was well-packaged and had absolutely every terminal, zip tie, etc that you will need when installing. So in short, hard to beat for the price!

Fantastic Sub Box

A very well-built and nicely carpeted sub box, that looks great, and should prove to be very durable, as it is constructed with 3/4" MDF instead of thinner material of many other boxes costing more than this.

The black carpet makes more of an impact than the typical gray carpet, and the 5-way binding posts are much higher quality than the typical plastic spring connections normally found on sub boxes.

Very happy with this purchase, and would absolutely consider another should it fit my needs of enclosure volume. (It's not worth the extra time/effort to make a custom box, when this does the job just as well, and comes pre-lined with poly-filled and pre-carpeted)

Sturdy enclosure

This is a very well constructed box, well sealed and solid. However, mine arrived new in the box and every corner had the carpet worn off and bare wood showing. Also, mine was not lined with poly-fil and the terminal cups were on the sides rather than in the back as it appears in photos- no biggy but that did influence my decision as my install would have been a little "cleaner". All in all it sounds great and seems extremely durable.

Far superior value than other kits

I am not normally compelled to write such a lengthy review, but felt I had to given my "TOFTT" attitude with the 1 star review I had read.

The thing that drew me to this kit was the price and reality that the other inexpensive kits look like a joke (see Boss Audio KIT-2 or Install Bay AK8). I am really happy with this kit as it provides way more wire than the two aforementioned kits and provided plenty of throughput for my set up. On top of the quality, it matches my blue theme so I am happy with the aesthetics too.

One personal note on the reviews of this kit versus others: I considered the other comment about $50 kits (and looked at the NVX XKIT82 and Kicker CK8). I put thought into those kits (Pure copper vs CCA) and watched the Sonic video, but the reality is I am running a 400W RMS two channel amp (Rockford P400X2) and for not that long of periods (never more than a couple of hours). The wire never gets hot, it's still made up mostly of copper (confirmed with Belva tech support), and it saved me a ton of money.

Reality check time: Save yourself $20-$30 and get *this* kit vs others if you are running less than 500W RMS.

Budget sub that hits the lows.Used as a shop subwoofer. Read review for details

I was looking to take on a simple project: Can you build/assemble a dual 12" subwoofer box for use on a 5.1 channel home theater receiver/amplifier system set up in my shop. So I purchased two of the Hifonics HFX12D4 subs and a prefab dual 12" vented box. Powered with an external class d amplifier that pushes 300 watts I had it together in less that an hour and mounted on a shelf in my shop at home. The subs are still breaking in as I do not listen to music in the shops except for the weekends. I am very pleased with the increase in output and lower notes as I get more and more play time on them. It is a great sub for what you get dollar to "boom" wise. For my application they work great. Service and shipping time was fantastic from Sonic - only 2 days to my door.

Sounds good (for the price)

The main thing I want to say in this review is; make sure you know what you are getting. With plenty of air space (2 cubic feet per sub) and no where near the peak power (around 100 watts RMS) per sub they sound great and should last a long time. Buy you cant over power these things on a cheap amp and expect them to last. I built a 8 cubic foot box ported at 34 hertz and ran 4 of them on an Alpine MRP-500 and they got very LOUD. http://imgur.com/3pw384k I would also expect them to last a long time at this power level, but don't know for sure as this was a build I did for a customers vehicle.

This is my third HF dvc 12 inch subwoofer. Not because they are blown or quit working but because they work very well! I have them in a sealed box and listen to all types of music.
Great buy for under 50 bucks.

Best Value!

This was already the best deal for a 3/4" MDF dual enclosure I could find, everything else in this range is 5/8".

For the price I wasn't expecting much.
However When it arrived found it is of good build quality, with decent carpet.

They already lined the inside with polyfil, more added value.

Then to top it off, found it has really nice gold plated screw type wire terminals. Better connection and added peace of mind that connections will not come undone.

This is probably the best deal/value on the internet for a dual 12 enclosure. Probably why it's backordered at time of this review.

Very Happy!

I bought 4 these subs as a temporary replacement. My old subs finally went out. At first they sounded ok but i had to slowly break them in. I was smelling the voice coils but after the break in i don't smell them no more. Currently running a Hifonics Brutus 30 year anniversary amp pushing 1700 at 2 ohms. I built a vented box tuned to 35. I can listen to all kinds of music from 70's music to rap. They hit pretty hard but i think it comes to how you design the box and setting your gains correctly. The only issues is the plastic cover on the bottom will rattle on the low notes so i took them off. I gave these subs four stars due to not having push terminals.

Theyre power hungry woofers and im still shocked how good they sound

for the price not to bad

For the price they knock pretty hard you're going to need 3-4 to get the job done tho

AMAZING SUB DIRT CHEAP PRICE

I was shown this woofer by a local car shop here in Memphis I am into car audio and we were having a conversation. I bought 2 of these woofers and have them wired in parallel to a 600 watt 2 ohm amp and boy it sure does BANG in my truck. You guys better order these woofers while they are still at this bargain of a price. I highly recommend this to anybody who was the best "bang for there buck" pun intended. I am completely satisfied with this purchase.

Cheap

Gets the job done at a fair price. Easily double the price in local stores

RCA Audio wires for Car Amplifier

Highly recommend. It was worth paying the extra price for these wires which made it easier for the installer and makes the system work great.

Best BANG for the buck!

I ordered about 4 of these subs. So far they have been fantastic! For the power to price ratio, you cant beat them!

AMAZING SUBS

i just received a pair of hfx12d4 subs, and they hit really hard, i conected them at 2ohms in a kicker cx600.1, each sub is getting around 300rms, and they hit really good, i had own punch p3, jl audio w3, kicker compvr. im very impress with sound quality, they hit almost as good as the kickers compvr, i reaally recomend them, the only thing that i dont like about this subs are the old connections.

Happy happy

I am very pleased with these subs they slam and it's a very good price highly recommend these subs!!

Complete kit

I ordered the kit with an amp. The install kit was complete. Seems other kits never have all the pieces. Great value!

decent entry low budget sub, for a lil boom

These arent really that bad if you just need a lil boom added to your ride. i had them in a sealed box with about 1cft each and on a 600 w amp. sounded decent for what you pay.. i would suggest these best in an open cab environment, not a truck.

Hard hitting

I would recommend these 12s. Because of value and how hard mine keep hitting

Great value

Great product..soundz good , lookz good , kant Complain about pricez..

Awesome subs

One of the hardest hitting subs I've ever owned. Great sound and bass!!

Nice for the price

Bought this sub to hold me over until I save up to get the sounds I really want. This thing hits pretty hard for 30 bucks. Not too bad. I have it in a ported box. For the money its worth it for any budget sound system. Will recommend.

By Derek on February 1, 2018 Verified purchase

One was good the second blew in the first hour :/

I would recommend it if you plan on using them for high notes

Over rated

This is by far a good sounding sub. My issue is with the power ratings. It says it can do 400 watts rms. I played the sub only 2 days, and it blew. If you underpower the sub to only about 300-350 watts, you may be in a safe zone.

Worst Sub ever owned

I bought a pair of these for the wife's truck and a month and a half later they were done. I tried to return these but Hifonics stated they don't accept returns unless it's a defect or shipping damage related. The "dust caps" are really there to cover up the pathetic size magnet. My uncle was impressed with the size of them when they came in. I had to remove the covers to have them fit my sub box. I sent a picture of them to my uncle which read "It's a small world after all" shocked on how small the backside was. He thought it was the funniest thing ever. These are cheap for a reason and I would suggest passing on them. If you are on a budget; there are other subs around the same price such as Boss which in my opinion are superior to these.

By Manuel on September 29, 2017 Verified purchase

Awesome

Love the subs, love the price. They sound awesome in my Honda CR-V but I think the ported box I have them in is crap so I will be trying a sealed box real soon.

Great Speakers!

Great Speakers! Awesome bass! Will most definitely buy from you guys again and buy more Hifonics products!

Hifonics HFX12D4

I have read some good and some bad reviews about these sub's, but mostly good so I decided to give them a try. And I can say that these sub's does not handle wattage. I had them wired at 1 ohm on a 1500 watt mono block only giving it about 1100 watt rms, since they rated at 400 watts RMS each which should be good but they start distorting quickly and losing bass my amp is not even half way up. I even wire them at 4ohm and it's the same situation, good at low volume and losing bass at high volume. Wouldn't recommend to anyone wants good bass for cheap

Hifonics HFX12D4 Subs making it go boom!

i was planning a budget build for my sisters first car and didn't want to spend to much money doing it. I knew of these subs from awhile back and never really gave them a double look until i heard them in a car at a local shop. I was impressed how they sounded for low end budget subs, but that's just what im looking for. so i did a price research and found them here on SonicElectronix.com and said heck ill get these and im done. well move forward a week later, i installed them in a ported box to specs and used an old kenwood amp i had laying around, feeding them about 275-300 watts rms each, oh man it was very impressive and im glad i chose these lil bad boys. i would use these again and would recommend these for anyone looking to build a low power budget system that ll be perfect for a daily driver or for your first timers. these guys drop some nice boom for the price.

Just try a pair.

I needed a pair of entry level subwoofers. When I checked out the price, I was a bit skeptical. I installed them hooked up to my 2 channel amp pumping 375 watts RMS and they handled the power with ease, sounding like most high end setups. I really did not expect these subs to perform so well. They can thump so hard. But always break them in slowly. These are the best you can buy for the price!!!

A++

These are great. If you are looking to enjoy your music and not looking to set off parked car alarms from 20 ft away then these are perfect. Especially if these are your first buy. They have great performance for the price. Respected brand in my book for over 10 years.

By Brandon on March 20, 2016 Verified purchase

decent priced entry level sub

got 2 of these along with a sealed box. broke them in like you should with any sub woofer. sound very good for such a cheap sub. never had any problems with them. dont know if they will truely handle the full 400w rms power or not. only ran about 300w rms to each of them. very pleased with how they sounded when playing rock/metal (METALLICA) nice bass drum hits. sounded pretty good as well on pop and rap music. overall a good deal! id recommend them to anyone on a budget that wants some decent bass.

By michael on July 29, 2015 Verified purchase

I've bought these before they take a beating unbeatable for the price good bump for the buck

Having owned these before I knew what to expect and for the price is unreal best bump for the budget buck.

By Barry on August 18, 2023 Verified purchase

Good for Entery level

For a 12 inch subwoofer, If you expect competition performance out of this sub, don't get it, if you want just something for the low end of your music, this works well for just that. This is entry-level, so don't expect to blow the doors off with this, however it does have good sound.

By kenny on June 12, 2021 Verified purchase

Great sub for the money

This is exactly the subwoofer you could hope for with the price tag. Decently punchy and has fairly good lows. The sound is gonna come down to your box size on this one IMO.

By Angeline on October 22, 2020 Verified purchase

Cheap price, cheap subs

Don't buy cheap these cheap subs, If you want to install them without amp you'll be fine. I hook up with a 600 watt amp hooked them up to 2ohms. Subs only lasted 2 minutes into song and then burnt out. They look good but speakers suck.

By Anonymous on December 14, 2019 Verified purchase

Great product

Exactly as described and more. Loud deep bass without rattling noise

Decent for the Price

Subs hit hard sometimes, I feel that they have a decent frequency response as they only hit some bass notes hard and others not so much, seems good for the price, it's pretty good.

You get what you pay for I'd say! I may need to run a better amp or better EQ though so who am I to say.

Best Budget Subwoofer

Best subwoofer in this price range. Got one of these as a temporary sub, hook up to a Fosgate R1200D wired to 2 ohm, gain half way (400 rms). Great flex and deep bass tone for the price. Do not run over 600 rms as this sub cannot take it's peak power.

Ok

They sound really good look ok so I would buy them again

HFX12D4

You can’t beat the price . They sound great in a ported enclosure

Great little sub for the price

Good little sub for the price. I purchased it for a home powered subwoofer setup. And it preforms pretty well in a 3.4cuft@24hz enclosure on 160w. Missing a little bottom end, but overall a great sub for 25 bucks. Only thing I hate is the ugly plastic magnet cover

Sub Dual set

Picked these up as a Duo.. who doesn’t like duo’s ;) if you know what I mean.
Anyhow they kick quite well. Doesn’t feel cheap or anything. Fairly easy to install.

Awesome bang for your buck! Great basic sub-woofer

Great Value for the money, sounds great for the price, however for the price obviously its not going to blow you away, you get exactly what you pay for a good basic sub-woofer.

I had these in as a temporary solution, and i ran them way over powered, all the time.
I was amazed the abuse they handled and for an entire year!

Great Sub love them

I bought 2 sub. I was surprised at how good it sounds. Im running it off my 1000watt Bose amp with the gain up about 3/4 of the way. It pounds....Great value for under $60. I would recommend this sub to anyone on a budget and wanting a good sounding sub.

Hifonix HFX12d4

If I want just a little bump in your trunk..this sub is the st inexpensive way to go...miss and highs hit great buy u won't get any lows...good sub for hard rock/ metal music..hits the annitial beat...think if you were gonna build a wall in your Tahoe or suburban..and put like 16 of these in...that's 16 for under 500$ !!!

Subwoofer enclosure

Good quality would buy again
Good prices
Always love sonicelectronix

great speakers

This speakers sound awesome with amp inside homade box I would recommend others to order from this place great products

Good Sub

I bought this sub to replace my Alpine R12 in my extended cab GMC 1500. I was surprised at how good it sounds. Im running it off my 500watt Memphis Audio amp with the gain up about 1/4 of the way. It pounds....Great value for under $50. I would recommend this sub to anyone on a budget and wanting a good sounding sub.

Great Set

Some friends told me about this brand of speakers, as a professional installer, i never had the pleasure of physically encountering a set of them. Decided to purchase a set for a display in my truck, Could not believe the sound quaty, would recommend top anyone

Excellent from product to shipping

My 3 Hifonics HFX12D4 12's look great and sound great. Thank you sonic electronix.
I would recommend sonicelectronix to anyone looking to purchase quality stereo equipment. Shipping was very fast even during the holidays!
More than anything, the prices were most outstanding!

Love it

Only had it for about a week now, and its really powerful, only have it hooked up to a 200 watt amp, it pounds really hard in my jeep. only using it at about half its power and i couldnt ask for any more. Sounds as good as my brothers rockford fosgate

Awesome

I installed these in my 2004 Jeep Grand Cherokee, they needed to have holes in order to fit my application. That being said, they sound great and are an extreme value.

By richard on July 1, 2023 Verified purchase

Surprised by performance

I had always been a JL guy at heart. I've owned mtx,fosgate,image dynamic and the list goes on. My budget is tighter than it used to be. This sub competes with those guys and at about 1/3 the cost or more. Deep sound crisp sound but can hit fast too if you like that double petal bass sound. I will buy more for my other car.

By Barrett on January 17, 2020 Verified purchase

Excellent sub for the price

Blew up one of my mtx so i tried out 2 of these with a rockford prime r500-1 and immediately noticed quite a difference. Very nice at low to mid volumes. For a low dollar system that still pounds these haven't disappointed.
