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.

Quality Product

Works very well with my Rockford Fosgate sub system in my car.

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.

good deal!

Pretty decent value for the price. Worked out great, thanks.

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

Usable

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

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.

price is right

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

Accessories for product

Just what I needed and made installation so much easier. Thanks

awesome products

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

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

good wires

I like the wire kit I got with my amp it seems to be holding up goo it handles the power of the amp I got but I would of gave it 5 stars all the way around but I wold of like the ground at less 2 more feet for good use but over all its a nice kit

Good stuff

Great product last a long time good value for the money.

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

Cable

Good product fast shipping awsome seller... keep up the good work.....

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.

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.

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

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 .

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!

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.

Perfect kit

Comes with everything you need. Works good with my 800w system

By Chad on May 14, 2020 Verified purchase

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!

shaking my head lmao damn...

well kicker has always been a well known brand and made loud efficient subs but me and my girl had purchased 3 of these cvr 12's and have them running on a hifonics zues 2400.1D at 2ohm and they sound super weak mind u I have them set at 2ohms at the amp; is the amp is pulling half its power but still they should bang like the old cvr's. I had recently bought 3 hifonics Hercules and had them running at 0.67 ohm at the amp subs ran in parallel. and they banged but eventually they blew after only 2 weeks of running them here and there they literally were smoking lol.instead of upgrading to the cvr 12's I should've went w the new hifonics brutus subs they prolly would've sounded way better than these kickers horrible im disappointed really ima put them at 1/2 ohm and see if they pound a little better and can handle that zues amp or their goin back...I guess what im saying is if ur gonna ever go w a kicker sub id recommend the solo baric L7 they have always quaked.!!

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.

Better Than Expected

I saw these subs a while ago but looked at the specs and didn't want to purchase them. My audio guy recommended them to me so I decided to give them a shot. I have them in a custom box in a Caddy truck and they quake. Good, clean, bass. Reliable subs, no complaints here. I'm not sure of the wattage handling because I'm not using for competition purposes but I've ridden 3 hours blasting them with no probs.

bad boys

Kicker says it all they will rock you world trust me ive had a lot of kicker products and still do they hit so hard and clear on every note i recommend these.

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 buy

These subs are great i ordered 2 of them. the hit hard and have great sound quality. I would buy again

good sounding subwoofers!

These subs are nice looking I have a 03 Buick century. Furthermore these subwoofers hit hard most people say that you cant have good sound quality with kicker subwoofers however you can it is all in the control settings of the headunit and the amp whatever you do try to keep your gain as low as possible and bass at reasonable level and you will do just fine kicker cvx can take high excursion and most important hits very hard

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!!!!

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

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

Clean sound while getting pretty loud!

I installed one in my Supercrew powered by a 400w Kicker amp, and lets just say, I'm more than happy! It sounds so much cleaner than my previous pioneer 12. I would definitely recommend this!

Amazing

I have 2 of these hooked up to an Alpine m-500 amp and they sound AMAZING. Could not be happier with the setup and the sound quality. I definitely would recommend this to anyone looking for good quality subs.

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.

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.

Worth the extra $$$

I have owned 2 of these 12" cvrs for almost a year now and they continue to impress me and my friends. I have had no problems with the subs whatsoever, they are hooked up to an 850 mono block amp and that pushes them just fine. I have even had a small dent on one of the subs and it hasn't effected the production of hard hitting bass that anyone taking the time to read this would find awesome. Overall there's a reason they are called Kickers.

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

i used to like kicker until i owned two of these...

I used to be a kicker fan i thought kicker were decent. My friend had two of the previous model cvr's and they hit hard so i figured the newer model would be as good. I was wrong. Let me start by saying yes i have them running off 500 watts rms a piece but i have the amp cut down and within a minute they start getting really hot and smell awful and they hit nowhere near as hard as the previous model if i knew i would have used the money i spent on these and got a set of type r's or the new type s's for the same price or cheaper. People if you want cvr's get the previous model (the ones with the silver cone) ill never buy kicker again.

Good deal.

I purchased this for the value. Everything you need for a simple single amp install in one package. Good quality with good value, thanks.

Great Value Kit!

I would highly recommend this package to anyone looking to do a cheap install, i have friends who got these before and its nice, simple and cheap!
Never had any issues, great value!

12'' cvr's

Had 2 12" cvr's running on a jbl gto1201.1II. These subs sounded very clean and hit really hard. For sure would recommend these subs to anyone looking for a nice clean sub.

Ok. not the best kit.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

By Lloyd on December 10, 2015 Verified purchase

Ok value

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

Great value

Does the job does what it needs to do. It was packaged nicely.

You get what you pay for....

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

Was surprised with the quality of the copper and actual size of the wires compared to other cheap brands like Schoshe. Worth every penny.

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!

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

Great wires!!

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.

The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.

Thanks again Sonic!!

Works very well, wish it included longer zip ties but overall a good kit that has true 4 gauge wire!

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)

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

great box

Perfect box just what I was looking for. Fast shipping

Very well made products

For the price, this installation kit is great. You can spend 4 times the amount for killer connections but if budget and functionality are key, this is the best.

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.....

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 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.

A Bang for your Buck!

This sub-woofer from Kicker has not failed to impress. I have this particular sub-woofer in a ported box powered by a 1500watt amp, and I must say the sound quality and power is excellent. For a single 12" sub, it sure has great sound output. I have had no problems with it thus far.

Pros: Sound quality, range, output, LOOKS!

Cons: Peak/RMS rating (wish it could handle more)

This sub-woofer is worth the money.

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.

Very happy

Great upgrade choice for me. Had some issues but were fixed n now sounds fantastic. Boyfriend said you wanted boom you got boom. Lol

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.

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!

Subwoofer enclosure

Good quality would buy again
Good prices
Always love sonicelectronix

Great Subwoofer

I have this 12" Kicker in a sealed 1.25 cu. box and the sound, sounds great. The first initial install of the sub sounded weak when trying to go high volume and the bass could not hit any hard. But this was due to not giving this sub a couple days of low volume break in periods. I am using a 300.1 kicker amp and what I can say in my opinion is WOW! I can get low volume full stereo bass and now high volume long bass boom. All in all, I am happy with my purchase! (I can only imagine how much more bass I would get if I had an amp 400 watts or higher...)

Decent entry level subs, good price!

These are good, entry level subs. I had a set of the 2007 versions, then upgraded to these when they came out in 2010. 1.2 cubic feet per sub with some acoustic filling in a sealed box sounded great in my 300M, wired to a Kicker KX600.1 amp @ 2ohms. They were getting about 300 watts each, and that suited them just fine. I upgraded to a Hifonics BRX2100.1D amp and a slot ported box to try to get more output, and my friend warned me I was gonna smoke the voicecoils. No way I thought. Turns out he was right. I was bumping loud as heck one day and I noticed it sounded funny. Smelled something burning, pulled over, popped the trunk and sho nuff I had magic smoke pouring from the left speaker. Long story short, run these in a sealed box with moderate power and you'll do fine. Want something much louder, upgrade to CVX's or L7's.

Still Running Strong

From my previous review about the WOW factor on this 12-inch subwoofer. It still amazes me how much bass still thumps from this subwoofer using my 300.1 kicker amp. From my 2015 review till present (2020), I am still a happy camper for buying kicker subs!!!

Everything I Needed

Used this kit to run an amp to the trunk of a 2015 Kia Optima. Ended up trimming about 1½ft of excess to help clean up the install. Everything seems to be good quality. Ran the power wire down the driver's side and RCA & amp signal wire down the passenger side to avoid any interference. Plenty of length of everything for a full size sedan.

Excellent Amp, Price, and Performance

I purchased this amp about a month ago. I installed myself and it's hooked to an older RF T1 Dual 4ohm sub (equivalent to the current RF model P3D4-12) and wired into a 2ohm load. I built my own 2.25 cu ft vented box. Man does it pound! It's in an Accord and I've never had anything perform better! I'm the kind of guy that always seems to push the limits of my equipment. For the first time in 15+ years I have an amp that I don't have to turn up all the way. With the bass knob set at 1/4 to 1/2 I can be heard up to a half mile away! I LOVE this amp!

Great Amplifier. Recommended.

Pros:
-High RMS power rating.
-1-Ohm stable.
-Runs cool to the touch, luke-warm when pushed hard.
-Relatively small footprint.
-Remote level control w/cable included! Yay!

amazing for the money!

This amp is a great little amp!! Powers my sub with full potential and is cool to the touch!

Great Amp

Bought this amp a couple months ago.
I installed it myself.
I use it to run 1 JL 13tw5-3

It is enough power for my purposes, but I don't think it pushes my sub to its limits.

Great amp for the price though!

Incredible Buy

I was very cautious when i went to buy these subs with the package, but for the price, i couldn't find a better deal! i have heard many subs ranging from jl's to visionik, and these, (BY FAR) hit harder then any of them. the sound quality is good and this package shakes my entire car! i've owned them for about 3 days, but i wanted to write a review right away so people have something to base off of. Incredible package, i highly recommend them!

Best thing ever!

When I bought these i knew buying a package deal probably wasnt the best thing to do and i figured it would hit okay and sound alright, but I was so wrong. I got these installed only yesterday in my 03 jetta and I couldnt be happier! The 850.1 precision power amp was my biggest concern and I thought it wasnt going to supply enough power but once again I was wrong. Cant wait till these really break in. They hit super hard!

Great Amp for the Price

Just bought this amp, and so far am loving it. Have it hooked up to an RE Audio SEX 15 at 2 ohms running in a 2 cubic ft sealed enclosure, and it pounds.

Definitely impressed.

Bought it for the fact that it had the speaker level inputs and remote volume knob to integrate with the factory stereo in my wifes SUV (she is not into car audio at all...)

Was the perfect compromise for us (satisfied my obsession while not breaking the budget)

Don't let the off brand throw you off!

I was very scepticial about buying this amp for it being a class d mono block. After hearing good and bad things about them I went ahead and ordered it to power 2 12" kicker CVRs and let me just say that it supplies more then enough power to handle the 2 subs just fine and the extra bass knob really is handy for adjusting the subs amps output. It has gave me no problems at all and has never even over heated. The only small downside is that the amp does not receive the high frequency bass tones as well as normal mono blocks or 2 channel amps. Overall very satisfied!

beast of an amp

This amp is the beast of all amps. I've owned a lot of amps and this is the greatest. Pushes my JL Audio w12 perfect, great sound does not get hot, just a little warm. If you are looking for a great amp at a low buget this is the one that out performs all others.

Budget Amp

I've owned this amp for two different sets of subwoofer setups. The previous was for 2 12" Kicker CVRs wired at 2 ohms. I had that when I barely knew anything about a system. I gave that amp hell for an entire year, and it never quit. I even mixed up the ground wire and power wire once and turned the car on (blowing the inline fuse). It was still a trooper.
Now I have a single 12" Kicker L7. I have it wired down to 1 ohm. I had the sub lying around, and decided I wanted a cheap amp to throw on it. So I decided to go with this. And it'll definitely push it. I have the L7 in a ported ground shaker box, and it'll slap. I have a 4 door Tahoe so there's a lot of air it has to push. I tuned the amp with a digital multimeter, and I believe it can put out more than 850 watts RMS @ 1 ohm. It does get warm to the touch, but I also don't have it where it can optimally ventilate. The most I've ever played is about 2 hours straight at 3/4 of the max I tuned to.

PROS: Solid amp for the money. If you're on a tight budget, this is the amp for you. Does at least its rated amount. Nice exterior design.
CONS: A bit larger than I'd like it to be. It does get a bit warm, so just make sure it can ventilate a little.

Good kit for the price

The power and ground wire are fine , speaker wires are interesting. One side has square and the other is round which makes it very easy to know what you hooking up to what. Came with everything it was supposed to.

By Daniel on September 12, 2024 Verified purchase

great budget amp - does rated power

got this hooked up to a Alpine S 15" at and it PUMPS. Measured 34.6V into 2 ohm with no clipping, thats a true 600W at 2 Ohm

Amazing

These are fantastic. i am a 16 year old boy, and would recommend these to any one. They hit HARD. Extremely impressed

Worth every penny

Though I never heard of precision power, the amp and subs do go well together and they hit HARD. Don't hesitate buying these. Kicker is one of the best brands out there and the amp powers them fine.

Love there stuff been back several times will order everything I need form them

LOUD AS... !!

Just had these installed in my 2007 Hyundai Entourage with its stock 13 speaker Infinity 660 wt system . The Kickers and Precision power amp just pound the crap outta my van .

I only turn The Sony head unit up to 25 or so with amp control on half . This unit goes to 50 but that would blow my speakers lol . Nice deep bass too .

My sister inlaw had 2 JL Audio and a 1200 wt Zapco in her durango but i think these hit almost as hard and her system was 2500$ lol .

Thanks for the great deal Sonic ! I couldn't find this big of a deal anywhere else . The sub box was very well built also .

Good Package

I installed these in a 2012 Chevy Cruze, and they are awesome. The subs sound great when they are working. I've had trouble with the amp overheating after 15-20 minutes of hard playing. Also, the bass knob hasn't worked correctly from day one. I need to contact Sonic Electronix about these issues. Overall, this is a good package.

Kicker

The price for this is phenomenal, you cannot get a system which kicks harder for the price. Sub woofers are also good quality, something you would already expect from kicker.

nice

Money well spent. I highly recommend this product and the price is of the hook. Killer bass if this is what you are looking for.

WOWWW!!!!1

Wow..... let me just say wow. this bundle was great had no issues insatalling everything and once i figured out the best wiring on the subs let me say wow!!! Very pleased with the kicker comps very satifsying. Was thinking original about getting a ported box but no need i can barely breath in the car when i have them beatting at full power. If your still learning like i was this is a for sure recommended kit!!! No complaints at all from me!!! : D
