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.

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.

BELVA amp kit

Not much to say, its an amp kit. Great value.

great product

Works great nice tight packaging and you get everything you need for your amp. Also it is true 4 gauge wire unlike some kits that advertise the wrong gauge wire this one is correct the correct size they say. Will buy again

Belva BAK42BL

Disregard the rating for durability because I have only had this product installed for a week. This kit is quality for the money. The wiring is a little sparse for 4 gauge, but it's definitely not 8 gauge in a 4 gauge sleeve. Loses one star for ease of use because the ring terminals must be crimped on by the user (which may be difficult if crimpers or a vice are not accessible to the user). Overall, I would recommend this to anyone on a budget or looking for a wiring kit for their first system.

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 kit on a budget

I bought this kit for a buddy of mine to do a small install in his 1999 Lumina. It's very flexible and more than enough for his little daily pounder setup.

Beat kit for the $$

I ran this to my 1200 watt sony amp with 2 1000 watt pioneer subs in a sealed box . And let me just say everyone in my neighborhood can hear me before they see me. I'm only at about 75% gain . I may but 1 or 2 more as back up for the future . People said the fuse holder dosent fit , I didn't use it , but all you have to do is back the set screw all the way out and slide out the inner holer and it will fit perfectly.

very easy

Bad thing is i had to buy extra gauging, metal pieces besides that everything is fine but if you want good cables buy(OFC) 1/0 gauge wiring itll save you time and 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.

Good Wire

Nice set. everything worked fine. Wire lengths were fine for installing in SUV. Would Buy again ... and have :)

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.

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.

Belva BAK42BL (Blue)

Good wires. Is four gauge wire and good speaker wire.

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.

my amps is west coast customs 1500 ccwith belva kit

I install my amplifier am the one one do it myself today I used terminator mtx dual 1200 watts tne212d very nice sound am so happy with it if you familiar with electronic stuff you can do it yourself cause best buy was going to ask me 400 dollars the more you learn the better you feel don't let nothing stop you from learning am very happy with west coast customs any of you who think of buying a amplifier you wont dissatisfied thank you sonic electronic and maxsonic who made west coast customs 1500 cc am out hiting the road cuise around with my Volvo xc70

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!

Well Built

Very flexible and not thin. This wire is the right size nothing skimped. RCA cables meet expectations, a nice fit. Dark blue as opposed to bright red. Hides well.

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

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.

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!

Beyond Happy

I was hesitant to put the VADM2 in my pristine all original 550i (E60). After replacing the factory subs they clearly needed more power, but, BMW being BMW leaves no room for typical after-market accessories. Therefore, space is/was a driving requirement for a 300W amp.

The VADM2 is perfect. Small enough to mount over the Antenna decoder and leave plenty of room for the PnP Technic wringing kit. ABSOLUTELY NO ALTERNATOR WHINE. Now the Logic 7 sounds like a rolling studio. Beyond happy. The VADM2 stays relatively cool and provides more power than my ears can handle.

If you have space limitations, want high quality gear, and are borderline audiophile that wants to maintain OEM look don't hesitate.

Curtis was a huge help in making recommendations and providing options. Top shelf customer service. Thx

Great box well made great value enough said ten word review

Awesome power for small foot print!

I needed to power up the 6 X 9's on my bike's batwing and with limited space, the NVX VADM2 fit the bill. I would absolutely recommend this product! Time will tell with durability.

Big Power Small Footprint

Power is great, especially when it's small. What makes this a slight bit better than the B52, is the standard speaker wire outputs versus the four pin molex style connection. Make it much easier to double up connections and go 2 ohm.

Small but Mighty

Nice amp works Great Really small but lots of power

By Kyle on April 24, 2020 Verified purchase

great sub for pickup truck

Works great for the application wired the coils in series for the bridged output on my amp and the whole truck shakes, sounds crisp too

Disappointed...

I had 2 of these hooked up to a rockford fosgate p300 running at rms power and within a few hours, both subs were out of commision. the voice coil went out on one, and the other simply quit playing mid song. I was only listening to them at about half volume of my head unit. but for the time that it did work it sounded excellent. i just expected so much more from rockford fosgate.

Powerhouse! Honest First Impression Install Review

I bought this amp to replace a broken Focal 2.350 2 channel amp installed in the fairing of my Harley Davidson Road King Classic. The amp powers two Focal 6x9s.

The first thing I noticed is the mounting holes on this amp are way too difficult to access for mounting onto a custom flat plate inside my fairing. There is just no way to mount the amp with that sized, tiny lock nuts and bolts. When I say small, I mean small. Then the other problem is limited access on the speaker wire side for inserting any bolt with lock nut because the speaker/power mounting is tight fitting where the holes are. So I drilled out the holes and used regular sized hardware, but even then it was difficult.

The instructions need to mention the speaker connection is removable for inserting the stripped wire with a tiny flat head screwdriver. It took me a little while, but I figured it out on my own. Remember to hold it upside down or use that tiny flat head to push the speaker wire tabs open.

I love that NVX included the RCA with molex adapter. I just plugged that in. Took 3 seconds.

When I finally got the whole thing installed and powered it up, I was absolutely flabbergasted on how crazy loud, crystal clear, and powerful this amp is with two high quality speakers rated at 150w RMS power handling @ 4 ohms. Ridiculous! Probably the best I've heard in a long long time. i even realized my Focal 6x9s are probably not good enough, if I want the bass to pound even better. Treble and Mid-range are spectacular loud and clear as a bell. I maxed out my Aquatic AV to volume level 40 and I could have kept going forever with this amplifier. I couldn't do that with my Focal amp, which cost more than double, is double the size, double less in quality, and isn't marine certified.

Now let's see this amp last on a motorcycle. Most can't and are vibrated into premature shorts on the 12v main power inputs. Time will tell.

Because of the mounting holes/tab situation, I subtract a star. If NVX makes little tabs with bigger holes for mounting and throw in the bolts with lock nuts/washers, this would rate a 10 out of 10.

Great work, NVX!

Compact power

This two channel amp produces good power and is small. Can hide amp easily with no one seeing it

By Justin on July 16, 2019 Verified purchase

throttle out

Put this on my bike to power my handle bar speakers and it offers plenty of power to still sound good even with the throttle open

Dubs

This little amp rocks. I accidentally fried my old MVPA4 amp. I had already purchased another amp to replace it (Soundstream 4ch.). This little amp is going on a bicycle with a couple of PRV 6.5" speakers. It is beyond stoopid loud/clean/clear/etc. Gets just a little warm after extended use. Currently have it on a motorcycle powering (2) 6x9's. Super loud/clear/etc. It would be a great motorcycle amp for 2 fairing speakers! VERY happy with this amp. If you are looking for a great, little 2 ch. amp, definitely give this one a try! I've been very happy with the NVX amps I've had (the fried one mentioned above was from 'driver error'!)

Sub box

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

pontoon sub

I needed something that would fit in my pontoon under a seat so it was covered. this did the job. got it powered from a old RF amp and it did the trick. nice little thump for the money

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.

Terrible design

I bought this amp from sonic almost a year ago and it’s been nothing but trouble. I have a very high sq system and needed a strong midbass amp. Very quickly after the initial install I began to hear crazy noise. The rca input leads have a chinzy connection to the amp and I was able to move it around and temporarily cure the problem. It kept getting worse and eventually makes a LOT of noise no matter what.
I emailed NVX asking how to order a new rca harness and got nothing. I said it would be nice to have one shipped for free but I didn’t really care about the couple of bucks, nothing. I rarely have the time to get into my system and this is a huge problem that I’ve given up on. Sure Covid and short staff but there’s been ample time for a response, nothing…
I would’ve bought more amps if they gave any support whatsoever on their products. So now I have wasted $200 on a garbage piece of equipment and need to make time to order a different brand and install. I can’t speak for the other NVX products but I would think twice about investing in the brand.

Solid Kit

Really solid wiring kit for a good price. It has everything you need to hook up a subwoofer.

great amp Kit

I really enjoy this amp kit with my kicker sub.

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 :)

Good wiring kit

I would recommend this kit. True 4 guage, actually good speaker wire. Rca longer than what I need since I have a single cab truck but no big deal. I will purchase another in the future..

Good value

Although the wires are made of CCA, I have no complaints. For the price and the contents of this kit, you really can't beat it. It works great for a non-competition audio system.

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!

Good kit for small amp

I have owned this and the red version of this and I'm happy with both installs. My one complaint is the power needs to be 20' and ground should be 4' other than that it's a good kit just a bit short.

By Anthony on August 16, 2015 Verified purchase

good truck sub

I installed 2 of these in a 99 chevy 2500 4 door they sound good for such a small sub. Depending on where and how you mout em ported/sealed depends on how they will sound in my case they added that extra low end fill i needed for great sound quailty.

Great value

Worked out great for me. Will be ordering a second

speaker

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

Good Power - good price

I got mine discounted due to some other issues with NavAtlas but still for the retail price not a bad amp at all! 150RMS @ 4 ohms x2 is very nice. Running 2 JBL X towers 8" with out skipping a beat!

I wish they would include a small screw driver though for the speaker connections as if you dont have a tiny flat head you better get one.

By Jonathan on April 5, 2022 Verified purchase

Its a cca wire kit...

Came free with my package and honestly didnt really use it for its intended purpose.... i used the 4 gauge cable to do my big 3 upgrade (4 gauge was better than the 8 gauge from factory) i used the rcas to run from my l.o.c. to amp. And the speaker wire cable to run my remote turn on (the gray turn on wire is garbage tiny tiny wire) decided to use the 14 gauge speaker wire instead for remote wire. Over all a good product except the gray remotw wire...

Does the job...

If you're looking for a quick and easy installation kit then I'd recommend this...contents in kit look nice and feel is premium although I would have to say the wires (power, speaker,and rca) are a bit thin but not too bad. Everything was easy to install and works rather well. No complaints here

Carries the load for a great value

This cable set is not pure copper but carries my 1200 watt Fosgate SUBS well without breaking the bank. I dont tax my factory charging system with too many amps and cant detect any loss these cables my cause.

Nice amp kit for systems under 1k watts

Good quality wires and at a fair price. The inline fuse is pretty solid as well. Can't go wrong if you are going with this for a modest-sized amp.

Great value box

Budget-friendly box great build quality has 2 12 at 600 RMS power the woofer box holds the pressure would recommend this box.

Good wiring kit

This kit came with plenty of everything I needed to install my amp and sub in my car. All I needed to buy were butt splices and a self-driving screw for connecting the ground. The ground wire was not super long but I think still ought to be more than enough for any kind of trunk or backseat amp and sub setup.

I would buy it again.

Great quality kit. Has everything you need to run an amp. Very solid pick for the buck.
I'm not a fan of the mini anl fuses cause if you blow one, you'll have to order one to replace it unless you are lucky enough to find a store that has them.

Not a true 4 gauge

Not a true 4 gauge. I compared it to my Rockford and kicker cables and it is alot thinner. But if you are on a budget it will do.

BAK42BL Belva review

Over all all the cords have worked out great for me. Only thing I would have liked to have seen is some kind of instructions on what everything was, as there were many unnecessary parts included for the amp that I used. Other than that, everything seems to be working great.

its awesome but

has every thing you need but the speaker cable is not long enough

So far so good! Used this to wire AMP installed into 2016 Jeep Wrangler JKY Sahara

Kit was straightforward and not complex.

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)

Love this box worth every penny really solid box everyone should buy it

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!

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

This amp kit gives you more than you pay for. You can’t get a 4 gauge wiring kit of this quality for less anywhere. I usually get oxygen free coper kits only but was on a budget for this install.

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.

By Tom on August 19, 2017 Verified purchase

Not too shabby

Definitely a really good step up from an 8 gauge kit, I bought this after I got a 1000W RMS HiFonics amp and noticed a huge gain in sound quality and definitely getting the power it needs a lot easier. However, some of the wire seemed to be a little brittle

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.....

great price and product

Product works great and for the price you can't beat that

Average

Got the kit for half off when I bought an amp so I can't really complain too much. I was a little disappointed that it didn't come with clear cut instructions or a list of everything in the package. It was my first time doing an install by myself so that would have helped a lot but I managed to get it done. I like the look and durability of all the wires as well.

great quality, budget friendly

i got this amp kit as a bundle with an amp, and worked perfect for my application.everything needed is included, nice flexibility

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)

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.

Coolest amp tiny and mighty

So I've been building systems for a long time in cars and trucks and never had to worry much about space for my amp to fit. Let me say this, on my custom motorcycle everything is tight. This little amp not only delivers ridiculous amounts of power but it handles it with no issues. So small it fits in my fairing on my cruiser and so powerful I decided to buy a second one. It's about the size of a smartphone and packs a punch of a gorilla.

I've recommended great products many times but I say 100% this will not disappoint you in any way. Unless you DO NOT WANT power lol!!

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!

Nice Modest Sub!!!

Purchased this Sub to put in my 09" Tundra. I've been running 300w @ 4 ohms to it four about a year in a sealed box. Sounds great for an entry level sub. Just remember, GOOD IS RELATIVE TO YOUR APPLICATION!!!!!. If you want bass below 40HZ this may no bet the sub for you. It has difficulty with most modern RAP music because of all of the 30Hz notes. However, this has been a good reliable sub and sounds great depending on the music your listening to and the environment you are putting it in!

Great value

Good product high quality everything you need is their complete and good

Brought my new boat speakers ALIVE

I recently put four 8" coaxials in my boat, running off the head unit power. It sounded alright but was underwhelming as expected. I wired this VADM2 up with two speakers bridged to each channel, and the thing ROCKS now, as you'd expect going from 17w per speaker to 110w. I wired the boat with power distribution and space set aside to add a VADM1 to power a subwoofer, but for the time being, I am going to hold off on that because of how the 8's perform now!

Surprising size

For the size of this amp, it is easy to put it practically anywhere. And it’s simple to use and set up. This little box packs a punch, and is worth the affordable price tag.

Bang for your buck

Put this kit on my hifonics amp on a solo baric 12 inch and works wonderfully

Works as Promised, sounds clean.

If looking for a modestly powerful 2 channel amp that fits into small spaces, this is the one. Easy to install.

Great For The Price

This micro amp is a great for the price! Installed this in my '23 Highlander Hybrid, powering a 10" JL Audio shallow sub in a vented box and it sounds great! I have the amp installed under the rear floor panel without any cooling fans or extra ventilation and it's never overheated even after 2hrs+ of continuous music. Gave it 4 stars only because it's has basic controls with no extra settings other than gain and frequency selection, but it really is a great amp for the size and cost. Highly recommend, especially if you're trying to save space.

Awesome compact amplifier

Great little amp, I have it bridged powering a single Kicker CompRT shallow mount 12" sub & it sounds GOOD. Very compact & fits into tight spaces, if you don't have much space to work with this amp is the perfect solution.
