As expected

Could have a better way to decide which wire to use as positive or negative. Only has spaced print on one wire.

Good Box

Great box does well with my subs would buy again

Great wire

This is some great speaker wire looks good works good and you get so much for so cheap

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.

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!!!

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.

Awesome

Great wire, for a great price! Love the color and looks very professional.

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 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.

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..

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.

Good value

It’s listed as (cca) which is copper clad aluminum wire and is cheap and doesn’t hold up good to high wattage. Aluminum isn’t the best audio wire, but it is copper clad and electric signals travel on the outside of the wire and that’s where a multi strand wire would come in handy. I think it’s a judgment call, but I wouldn’t buy it.

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.

ESSENCIAL NEEDS

WOW HOW VERY FLEXABLE AND THE RED
REALLY GAVE SOME KILLER LOOKS. WIRE
VERY GOOD.

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

Decent speaker wire.

Speaker wire is good. It works as speaker wire should.
My only grief with the wire is the thickness of the insulation. It's really thick, and in my opinion, too thick.
I have a very high quality wire stripping tool, but the thickness of the insulation made it next to impossible to center the speaker wire and my stripping tool always cut a bunch of strands of the wire. Not a real big deal in the grand scheme of things, though.

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 add-on!

Always nice to get freebie with purchase. Belva is always making quality stuff!

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.

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.

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

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.

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!

Great value

Definitely get your moneys worth! Would be even better to receive complimentary gifts.

Thick legit wire!

I use the wire for my ground and my 12v wire! This is good quality wire.

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.

soso box!

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

Great box

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

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.

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!

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.

Great Box

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

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 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.

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.

By James on June 1, 2015 Verified purchase

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.

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

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.

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.

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.

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!

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!!!!

Loudest and Toughest for the Money

So I bought this sub back in October of 2012 for my first budget sound system. It is in a slot ported r/t 300 box and powered by an infinity 1300a amp. I have to say that just one of these by it self gets really loud, especially in a smaller car ( I have a Corolla). Loud enough to rattle the car, and mirrors, and if you're sitting in the backseat, you can definitely get a massive headache, haha. With that said, they will not hit the absolute lowest notes in rap songs, nor do they produce the cleanest bass. But for the $49.99 I got it for, my Comp has been an excellent value. I will be putting alot of sound deadening in my car in the next few weeks, which should help improve the sound quality even more. Honestly, even though Kicker rates this at 150 watts rms, it can take 200 safely. Thats what I've been powering it at for the last near 6 months. From the inside of the car, this is really all the bass you need. If you're one of those people who wants to be heard down the block...well you might wanna spend some more $$$ on a Kicker CVR or an Alpine Type R. But for me for right now, this speaker dominates on the bang for buck meter (literally). And I have to admit, the design of the woofer itself looks pretty awesome compared to the generic looking subs offered by brands like Kenwood or Pioneer. When I pop the trunk, alot of people look at it and say "dang!" followed by nervous laughter. No joke. All in all, this is about the best budget woofer that you could buy and I would recommend it to anyone!

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

300 bangin!!!!!

I got 2 of these in a pro box with 1000 watt amp in my 300. These things beat up the block!!!!!!!!!!!!! best money i ever spent. Highly recommended. Only thing is guaranteed rattle but nothing a little dynamat cant fix.

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

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.

noise makers

yo wat up ppls they call me the crazy cuz I have 8 of these subwoofers. LOL! I have had my whole neighborhood call the cops on me at nite time becuz of my subs. if anybody wants low pice subs 4 a gud amounts of noise i would strongly recommend these. if u wanna check them out come 2 springbreak nationals in Daytona Beach,FL and come support my truck. Please and thank you.

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!

title

Great box well made great value enough said ten word review

great subs

Great sound quality if you connected with a kicker amp.

Straight Monsters :)

my very first system were Fusion audio audio 12's (CRAP) but i sold them and bought 2 kicker comp 12's (2010) model. and wow these things slap. i got them wired to a sony xplod 1000 watt amp. with a ported box. WOW KICKER ALL THE WAY!

Speechless loud kicker

Put these in a probox theyll knock hard makes alot of bass sound around inside your car

Great Product Highly Recomend Kicker COmps

I currently have 6 of these in my truck on 3000 watts rms doing 150s.. believe me its all about the box :) in 6 months I have only ripped the surrounds on 2 during a competition once... I replaced them and backed off a bit now its GREAT.. have 2 more waiting to go in.. 8 comp 12s should be fun

Decent for the price

I was actually disappointed these kickers. I have them wired into a 600w amp and it just doesn't hit hard enough. If I turn them up to high distortion comes into play. Although, I listen to deathcore and there is no real need for loud bass hits; I was still hoping for some mirror shaking. IN CONCLUSION: for the price I paid these subs do just fine for a starter set.

Worth the price for sure

Good quality item and definitely worth the price. Definitely recommend

kicker

i have two of these and a 1500 watt boss amp and they rattle the peoples rides beside me. i would strongly recommend these subs. Only get them if you want to be heard!

Great price

I would recommend this product because it gives great protection from the elements and makes a nice enclosure for the speaker.

Sub box

Good product I would recommend this sub box to anyone that is looking for a cheap n quality enclosed

Good quality for the price

I have 2 12 pioneer ts-a30s4 and it's working great inside this box

good value

I bought this to put some ID Max's in for my daily. Build quality is good and the price was right. The box was good enough for me to buy another for some first gen JL Audio 12W3's that I was selling.

Good solid box

Its a great box... small compact and puts out great sound...A+ on this. Carpet matched my existing carpet turned out pretty great im happy with it :)

loud

I got two of these and they are loud. Only 150 rms each and on a 400.2 pioneer amp, my neighbors can hear me coming down the street. They are loud but have terrible sound quality. If your looking for sound quality i would not recommend these.

great product

Comes with literally everything you'd need, fits perfectly in my 2014 dodge charger rt. Only think I had to buy in addition was a gauge to be able to lower the volume on the bass. Other then that I love it!

Great value

Worked out great for me. Will be ordering a second

The item did not live up to my expectation because it arrived empty and damaged.
But for the price its a pretty durable box.

belva 8ga BBSW127

I liked the quality very much and the cable was very flexible which made it easy to run.

Good quality cable

This cable which I got for free with the purchase of a Belva Sub-woofer box is pretty good. Nice 12 ga. cable with a very nice outer insulator. Nice and flexible.

Insane quality

I have ONE of these 12 inch Kickers and it is awesome! Dont let the 150w RMS fool you. that is all you need for these speakers. I have a little MTX amp that pushes this sub at about 100w rms per channel and it hits harder than most of my buddies 1200w systems. It hits the lows amazingly. although its not that good on the highs. But these kickers are one of the best speakers to by for this price.

AMAZING Subwoofer

Best subwoofer I have ever heard! HIGHLY recommended. This subwoofer has made me a Kicker customer and fan for life. Handles bass excellently and sounds amazing. And with the great price it is unbeatable!

great entry level sub.

I bought these subs and put them in a badpass ported sub box with a fosgate amp powering them and to tell you the truth they put off a decent amount of bass for a new basshead. I would very much recomend you spend the first 2 weeks just breaking them in. you will get a much better outcome.

Awesome Subs!!!!!

I would definitely recommend these subs to any first time buyers. They are the best subs in the price range without question. using the kicker zx300.1 to power them in a custom sealed box. I had neighbors a block down call me and complain of the noise inside there house!

Just what the product description says and it does it. No complaints here!

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)

i have 4 of these all in sealed boxes, in a truck, hooked up to a memphis 1000 watt amp (halfway turned up) and these things slam hard. one of the best systems i've ever owned.

BEAST!!!

This thing is a machine. I just got this thing yesterday. I love it. It whomps, and i only got it on the kicker zx200 amp. Can only imagine it on a bigger amp. Highly recommend!!!

Great Budget Box!!

Ordered my box and had it at my front door in 2 days! Great box. Its very well built and pure mdf and thick mdf wood. Nice carpeting. Only down fall i see is there was no poly fill and terminals are on sides instead of rear. I thought it was suppose to be this one pictured and both are the same numbers but different box but i am still very very pleased!

By Norman on November 29, 2017 Verified purchase

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.

Awesome with my dual JL 12w6v2's

Purchased because I needed a new box for my JL Audio W6v2's. Sounds great! Great solid construction, nice that it's already lined with polyfill, no air leaks and the black carpet looks great. Can't beat it for the price and sound quality with my subs in it is excellent. Guess it would be nice if the terminals were pre-wired but I soldered my own wires in. Love it, would buy again Box fits perfect in my '13 Accord trunk

These are my first subwoofers. I have them in a sealed box paired with a kicker zx 300.1 amp. They give great bass inside the car and enough to shake my side mirrors no problem and not that horrible sheet metal rattle you hear on some cars. I would go for the ported box package kicker has on here if you really want bass though.

Great value

Great box for the price I have two 12" pioneer champion series 1400 watts speakers in this enclosure and they sound great thanks sonic for another great purchase.

So for its been great

Sounds better than I thought it would I have two 12 rockford fosgate p3 and they sound great and the price was a great deal

Great deal

The box fit great in my trunk and sounds great

Tight Bass

I always try new subs in a sealed and then ported box. This Belva is a great value and a solid , sharp looking sub box.

beats good

I have 2 of these subs and they sound great. Would tell anyone to purchase them good bang for the price if u on a budget.

awesome product

i have 2 of these in a sealed box with a ken wood kac 8105d mono block amp. i have it wired at 2 ohms and its barely turned up all the way. i gotta tell yuh it slams really hard and after a hard days of work its nice to get a massage while driving home. highly recommend these

Decent Sub for a Killer Price!

I have 2 of these wired down to 2 ohms each at 225 RMS on a Kicker 450.2 amp and they do hit pretty hard for being so low in power, but both of them flex my doors, mirrors, etc!

great for the price

put two in a sealed box powered by the kicker zx 300.1. I was amazed at how loud they got because they are in a soft top jeep and my friends say they can hear me driving a block down the road. they are good for anyone that wants to add some boom to their system without spending a lot of $$

booooooom

These things are loud I had two in a Kicker spec box and i had police come to me at street lights and told me to turn them down

Very well built box!

Nicely built and good for breaking in any subwoofers. Highly recommended if you like that nice clear sound that cam hit that tight bass.

Great bang for my buck

I have to LMFAO at all those bad reviews bet they never realized 3 weeks. At lest before you go n turn up amp. Today is Aug 19. 3 weeks ago I bought n installed (DIY). My amp n remote were both turned to 2 gain will EVERYTHING ELSE was set 0. Yes at first could not hear it. But in long run worth it. By 5th day at 2 gain was raddling my mirrors. I only got one these bad boys. Due to out stock. I can't even fathom 2 these. Guys going.BTW I still haven't messed with amp or any settings. Pounder on that for awhile.....

Box

Looks good and easy to install speakers in. Made heavy for durability

beats beats beats

Ordered two of these to go with the two I already had. I must say for the price I can hang with anybody 4 12's hitting like a sledge hammer.

Budget bass

My buddy had a pair of these in a Sebring on a zx300.1. Sounded pretty decent. Definately one of the best bang for your buck woofers. Good spl.

sweet

I have these subs in my 87 gmc sierra and its loud!!!! Shake everything my steering wheel shakes. for the price its a great started system i love them

Subwoofer box

It looks really sealed and no air will leak and it looks very durable

Good value

I would reluctantly recommend this box. The one I received was already slightly damaged in the corner with carpet coming away from some of the seams in the corners even though it was brand new from eBay.

Great value

This piece of equipment is great. Makes my Dodge shake and I only have the one 12" in it

Awesome subs

I had two of these in a ported box with a kicker kx450.2. I have owned/intalled car audio systems for about 5 years or so and these were amazing for entry level subs. They hit close to my 15" l7 did. When hooked up right in the right size box, they are monsters. Definitely recommend to anyone looking to add a moderate amount of bass.

12" kicker comp

two of em are adequate for my full size caprice in a box's built to SQ specs. most everybody i have listen to it can't beleive it's only 300 watts... eh. the only thing i dont like is the wire terminals are spring loaded not the best design.

great sub for the price and power

Hard to beat this sub for the price when you get the 2 for 1 deal. If you want good bass without breaking the bank or worrying about low gauge cables, caps, or upgrading your power system this may be a great sub for you.

Wow...

These subwoofers bump hard. I didnt think they would because of the 300w max power but they do. I have them hooked up to a 600w kenwood monoblock in my 2005 Ford Escape and they sound amazing. I would definitely recommend this for people looking for cheap subs that sound great without having too much power.

Great buy 2 for 1

Great speaker very nice deep bass...and u dnt even have to have a good amp on them! i would recomend them to anyone!!!

wire

Pretty colors. NO issues with this wire but how bout a kit with the nice bullet ends so they can go into the AMPS real perty like and I don't have to hunt and peck for them and/or some colored heat shrink wrap so you know which one is + or - easier.

good woofer

Very good woofer for beginners sounds great i am going to buy one mere to have the pair

Amazing subs

Kicker is awesome. The subs look great and sound great.

Great Value.

This box is awesome for the Price. A little heavy and you must have enough room. It will fill a trunk or back of a SUV. I have two JL 12's ,which makes this a combination that beats. Low, long, stretched about bass that lets the neighbor's; who live a mile away, know you're coming.

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Perfect fit for my car.Love the carpet cover.Would recommend you carry gray carpet covered boxes.

Great quality

For the price is a very good quality enclosure, very solid and well made

Really nice box

I put 2 mtx sub and the bass is really deep,the best, the price is really good.

By Mag80 on November 6, 2016 Verified purchase

Worth every cent

I have installed 8 of these subs in different vehicles, they slam in the right box (2cuf a piece, and with a good clean 200w rms. if ur runnnig sealed in your trunk these may not be for you but in a suz or truck in a ported box you will be happy that you bought them
-brandon

Great Value

This is a great subwoofer! I had two of these in a ported box and they hit extremely HARD! My neighbors hate me because of these subs. They say they can hear me from a mile away!

Great purchase

The speakers sound really good. I have people ask me who I got those speakers from. I tell them Sonic. The employees are very helpful.

Great Value

Product works and sounds great! I reccomend anyone to purchase this brand (Kicker) at an great price from Sonic Electronic.

Great Sub

Before I had a Boss Audio 10, now I have 2 Kicker comp 12's. They are loud as hell, they shake the walls all over the house, my mom is always making me turn them off. I bought a 1000 watt kenwood amp to go with them and its perfect. Great for the price. (i got them buy one get one free)

cant beat the 2 for 1

Good sounding subs, definitely worth how much I payed for them. I have 2 of these in a ported box and they hit nicely. The highs and mids are nice but i have heard better lows out of other 12s. If you are looking for a budget system that hits hard then go with these

GREAT SUB BOX

SLAMS THE BASS FOR 2 12" SUBS HARD AND GREAT. WELL WORTH THE MONEY AND THE QUALITY THAT ITS MADE FROM WOULD BUY AGAIN FOR DIFFERENT CARS.

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Made out of high quality mdf nice tight bass highly recommend this box

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Solid product. I wouldn't put a subwoofer heavier than 30-35 lbs each in it thought. It's lined with polyfil so you'll have to cut a small hole where the terminals are but other than that it's a pretty good box for the price.

It's alright

I've had it for about a month and it is breaking in and sounding better and better , it replaced a lanzar that was 20 years old and that I paid $300. For back then . Even though it's not as outstanding as the lanzar , I'm getting used to it and it sounds good! Also it isn't as power hungry as the Lanzar , I have half a ADS Pq 20 bridged powering it and that's all it needs(200-400w) yes the amp is over 20 years old too , seen many rides and still bumps!!

A real kick in the butt.

Incorporated the sub woofer into my car from the trunk through the rear seat. Removed the extra padding in the center of the back seat to really feel the thump. Wife hates it, great selling point. She will not ride with me!

Beast

Hits harder in a ported box instead of the sealed. I've got sum decent excursion and they are not broken in all the way. This is kicker's entry level sub and is still a beast.

Nice Product

Install this on a 2010 VW Jetta n all I can say is that people turn there heads. Price is good and, any body that wants some bass this is it.

Awesome Transaction!

I received 2 of these subwoofers through a buy 1 get 1 and received them extremely promply. The value was incredible. I have wired them to 1 ohm which allows them to hit significantly hard and produce good levels of sound.

great subs

I bought the two for one deal on here and they arrived a day early. Great subs powering them with a kicker zx400.1 sounds awesome . gonna let them broke in then its gonna be sweet.

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Purchased this enclosure for my son's first system in his '16 Cruze. Great alternative to building a custom enclosure. Great match for the ID12s I had leftover from a previous system. Also, as always, Sonic Electronix has the best prices and ships fast.

By Anonymous on January 30, 2019 Verified purchase

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!

sweet subs!

These bad boys are awesome for the price. Great for anybody. They really knock. Highly recommended.

Good sub.

They alright jus needs more rms power.

c12

Good built sub and good for the price I own 2 can't beat the price I push these with a Kicker 300.1 after 6 mons still pound. I do recommend a Kicker or RF amp for these.

bang for the buck, and thats it

well i had these in my Jetta Wolfsburg. they were 50 bucks each so i thought it would be a good deal, but I highly regretted it. They do not bump or pound. It is a noticeable bass increase that you really cant hear from outside the car unless its quiet. They are not very loud and sure wont rattle the car fi thats what your hoping for. all in all it is good for adding clean bass to your system, but they are not hard hitting subs by any mean

Nice subs

These subs produce clean sweet bass. I have a Rockford Fosgate Prime 250 hooked up to two of them and it adds the perfect amount of bump in my Grand Marquis. Together the subs are 300 watts RMS and my amp puts out 272 RMS according to the birth sheet. So I'm not really pushing the subs too hard. You won't win any contests with this set up but if you want some extra bass these are a great choice. If you have the room, get this set of subs in the Kicker box! Sonic has them and I wish I went that route but that was my fault. ;-(

Dope

I got two of these wired down to 2ohms in the kicker loaded enclosure for 300$. Best money ive ever spent. For the price of these subs and a 500 watt amp, i couldnt be any happier. Literally these subs almost broke my rearview mirror.

good price....good speakers

If you want to add good sounding extra bass in your vehicle for a good price, these are the speakers to get. If you want to win competitions, get higher wattage speakers.

Nice

It's a good starter sub. My bro had 2 of them in his car with custom boxes and they hit very hard. He only had about 110 RMS going to each and they slammed good and hard. The highs and mids were excellent, but the lows weren't as good as they could have been. Maybe that was due to the sealed box they were in. But overall, they were good subs. Simplicity can be some of the best stuff. Get 2 of these and you won't be disappointed.

great deal 2 for1

i got 2 kicker comp subs and they sound great, i know people with higher wattage subs and they dont sound as good as the comp subs. they sure dont sound like entry level subs.

Awesome

Best sub for the price. I'm running 160 RMS into it in a 2.25 ft^3 ported box tuned to 33 hz. It rattles my station wagon pretty good. Definitely would recommend this if its all that's in your budget. However I've had it for about 6 months and looking to upgrade. Seems like there's a tendency to always want more. I listen to a lot of bass heavy music and it just pounds... But more is always better. Cant speak for durability much but I've been pushing it a LOT and its goin strong. This is definitely excellent for the price.

amazing bass, low power

I have one of these in the trunk of my 92 accord in a ported box i made and its paired with a 150w rms kenwood amp. When i turn it up, my mirrors are just about totally useless, just a blur. People can hear me over a 1/4 mile away (me and friends have tested this). I bought a small spl meter that maxes at 125db, and well, it gets maxed when my bass hits. I would like to find something else to see exactly just how loud this is. People always guess i have at least 2 subs with some big power, but nope. Just this one kicker 12 and a small amp. If you are looking for some serious thump on a very low budget, this is for you. You wont be dissapointed.

Cons -
Neighbors dislike me
bolts coming loose on car
broke rearview mirror

WOW!!!

Best kicker Subs I've owned. The push really really hard!!

Great Subs!!!

If you have a cheap deck, amp and wiring then these subs aren't going to sound very good as with any system. With the proper quality equipment these subs sound amazing for a low RMS unit. I have a Clarion comp deck, planet audio 1500.1 amp (at less than 1/4 power) and 8 gauge wiring kit with these subs in a sealed box and people with JL W3s and kicker L7s are asking me how i get them to hit as hard as i do. It's all about your setup. Don't put these subs on cheap crap! These are excellent subs and at a good price!

great deal

Speakers sound great. My 17 yr old loves them. He out hits everyone at his school.

great price

these are cheap and sound great

Subwoofer enclosure

Good quality would buy again
Good prices
Always love sonicelectronix

Great subwoofer

Let's just say I bought if for my girlfriend and its still kickin hahaha great speaker.

eh

I have two of these wired up. To get good bass sound you have to turn amp settings down. Yes they'll slap, or pound or whatever these people are saying, but it will be distorted if they do. If your just looking to add a bass concept to a bass-less system, go ahead its worth it. If your looking to bump, go elsewhere.

Great highs

These subs are by far the best for the price but only offer a high frequency range of responce, if paired with other subs that reach lower to contrast then these are perfect.

Amazing subs!

I bought two of these subs for my son and they hit hard. Way too loud for me I can hear his music 2 blocks away! Using a Kicker ZX 450.2 amp. The sound is amazing. Best bang for your buck!

good for the price

I have 4 of these in my blazer all at 1 ohm being powered by a lanzar 3000 watt amp an no one i know bass comes close to mine. I definately would recomened these subs to ppl who are on a budget.

12" Kicker 400w

I have had this sub for 6 mounths and it has been great! It was also a good price on this web site, it got it for cheap with 3 year warrenty and so far not one problem. It sounds great and i recomend getting it.

Great subs!!

These subs came in very fast as advertised and they pounded from the second i got them hooked up. This is a great deal for the price and EVERYTHING came as advertised. I had my whole system within 3 days.

Great Product

Just got this sub as an early christmas present and it BEATS HARD!!!!

Love this speak I have 1 single 15 powered by a 2500 watt earthquake class d and it absolutely bangs can't go wrong with this subwoofer it has clean sound and can take power well
