Belva bak42

This item works okay, easy to install, and good for price.

good package

Great value and worth your money as far as what you would need for an amplifier/subs system setup. Quality wires.

impressed

I ordered this kit because it was fairly cheap but I have to say in very impressed with the quality of the wire as well as the thickness of the insulation. It was much thicker than I had anticipated and was pleasantly surprised.

Wiring kit

Very quality wires and very pliable. Will definitely buy again

best bang for your buck

hooked up to my amp with ease subs bump all day long no problems installing except finding a good ground the ground wire could be a little longer but not a major problem.

Everything you need

This package comes with everything you need to install your amp and speakers. Great value.

Belva

Parts came fast, and seems to be a good quality for price.

Not bad

It was pretty nice the wire was a little bigger than i thought (wire is about as fat as a sharpie marker just the wire not the insulation), the grommet that came with it was way to big for the wire so i didn't use it the fuse seems ok the connectors are good didn't have trouble crimping. I had to drill out the ring terminals a little but wasn't bad; wire insulation kind of soft and easy to puncture.

Ok product

The product works. Not the best quality though. The cables are pretty lightweight. If I did it again I would spend a little more money and get a higher quality cable.

not enough

first the terminals are too small for the gauge wire for the power and ground and fuse. a lot of the things that came with the kit didn't seem to have a place with the wires e.g. butt end connectors, cable terminals, all were too small for gauge wire included. im having to run out and buy pieces from my local radioshack. the remote wire has nothing to even connect to my head unit making have to go out and buy more materials to complete my install.

great quality

I have this kit running a reaper series amp and the mofo 122x the kit is rated for up to 1000watts rms it has no problem with my application even though the amp and sub have a higher rms

Good Box

Great box does well with my subs would buy again

BAK42

Has everything you need to hook up a amp. Used it with a 1600 watt amp, works perfect never had any problems.

OK wire if you like red wire

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

Nice

Great kit comes with everything you need to set up your system. And its a really good deal for the price

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 kit

Great wire kit, the only down is its not OFC

Missing piece.

Took the cables out and noticed that the fuse was not included. Looked back at the product description and says the fuse is included. Have to go buy one now.

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.

Great Value

Instead of buying piece by piece, these packages are a better value if you are installing an amp from scratch, much cheaper way to get it hooked up.

Great wiring kit

I really love this wiring kit, it is amazing it is everything that the description said :).

belva amp kit

bought this thinking it was going to be a cheap amp kit but i was surprised by the quality. excellent in every way, most problems i've had in the pass were with the rca cabels going out but with belva no problems at all great company love there products and sonic prices!

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.

Amp kit

Nice thick wire but would prefer all copper but it works. Nice coated wire soft and maluble.

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

Exactly what it says

Wires are exactly as they are advertised, standard 4 ohm cable. RCA is a little short but I also drive a massive car so it's understandable. All in all, worth the money.

Fair price for cheap kit

I Have this kit because for a very cheap price it came with the amplifier. I know now that I would not spend more than $15 to buy this kit separately. Does not come with with enough connectors for the four gauge wires for a basic amp setup. And the fuse is meant for 8 gauge wires not four gauge so it does not fit. Overall wires are wires so the kit worked just fine. If you're running a basic setup without anything over expensive this will work for you. But if you spent the money on a nice system. Spend another 20 or 30 dollars and get a good wiring kit. Without the extra connectors wiring a capacitor with this Kit doesn't work either.

nice product

Every thing you need to run your gear..easy installation.

it is not 4gauge

It is nice and i wood get this set a gen butt it is not 4g it is good for the $$ but if u are looking for 4g this is not is . it will work for my 500 w amp but i wood spend a litt le more $$ and get the good stuff for 1000 w or more.

1st Kit

This is my first amp install so I only have second hand information to compare this kit. The power wire is very flexible which is nice if you're needing to snake through odd angles. The ground wirer is beefy. The speaker wires seem to do the trick just fine. My only real complaint is the connection terminals provided. Please do yourself a favor and go buy bigger better terminals. The eyes on the terminals is too small for any of the battery posts I've ever seen and the ground terminal (I grounded to my seat mount bolt) is way too small to fit. After a $2.99 parts run, everything else seemed to work just fine. Considering this is an entry level/budget minded install kit, I'd recommend if that is the market you are in. Much better kits are available, but the price jumps up rapidly.

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.

It's ok

It is what it is and does what it's supposed to do but if u are putting it in anything but a compact car u better buy more battery cable. This package barely reached te trunk of my Jeep Compass in a straight line from the battery.

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.

not bad for the price

Got this for a budget system in the wifes car. Going by the price I wasn't expecting much quality just the basics. Overall its a decent kit that contains all you need if you are on a budget. The wires, of course, are not true 4 ga but I already expected this when I bought it so no big deal. Zip ties are really thin so they break when you try to use them but that's why you get a bunch anyway. Fuse holder is nice though and wires are nice and flexible helping the install go a little smoother.

Belva kit

I had this kit hooked up to a Hifonics amp according to specs and wow. Coming from a guy who always wants to go the cheapest way, 30 bucks for this kit is perfect. More zip ties would be helpful, but this kit does provide great sound with minimal static interference. Wires are very flexible.

Amp install kit

This kit makes the install of your amp so much easier.

Best Value!

Very high quality ground, power, and rca cables for only $30! (or cheaper when bought together with an amp!) power and ground cable is made of that super flexible material, very high end, unlike those other cheap brands that you can't bend the cables, which makes the Belva kit an installers dream! Highly recommended if you need a good 4 gauge amp kit and don't have a lot of money to spend!

Awesome Price!!

For the price you really can't beat this deal. I installed this kit myself in my 1999 Ford Mustang Cobra and was able to run the power wire from my battery and completely hide it going through my firewall, along the side rocker panels, under the rear seat, and into the trunk with still three to four feet of wire to locate my amp where ever I wanted within my trunk. The amp turn on wire and RCA cable were sufficient but I chose to use a different fuse and fuse holder as I wasn't sure about the quality of the one supplied. I definitely recommend this product.

Not a bad kit

The wire itself is not bad quality at all. It's obviously not much comparison to true OFC wire but it still does the job. True to spec, very flexible. I have it powering my 500w rockford fosgate and it works just fine. Definitely a good buy for only around 30 bucks

Best bang for your buck.

This kit is impressive. Thick and flexible power and ground cables that are true 4awg. Very nice twisted RCA's. This kit even includes 20 feet of 14 ga speaker wire! For ** bucks? I would've gladly payed double.

The only con is that the fuse is a little difficult to hook up but you can figure it out pretty easily.

Works well

Good kit to instal an amp. I'm pushing a 1600 watt amp. Glad I went with the 4 gauge

good for a simple setup.

Did well enough to hook eberything i needed up but it was only a sub and amp. Used every last bit of length though to hook up to the back of an 02 intrepid. No problems with anything in the kit. First time doing this type of thing and had nonproblems.

nice sound

very good product at a pretty good price lowest i could find on net and sounds good

great product and price

Love every Rockford sub i have ever owned. Great product and great prices. I have had 2 p1 10"s, T1 15" , 2 12" p3s, and now i have one 12" p2 4ohm wired to 2ohms. Have a rockford fosgate prime 500x1 mono amp wited with a Belva 4 gauge wire kit. Sounds so good in the Belva vented box. Have this hooked up in my 01 frontier king cab. Also have my kenwood 6.5 running in here. I need dynamat asap. Also got my alarm from sonix. I have been ordering from here since 2005 i always recommend this company because of their prices and fast shipping. But this last order was the only time i had a problem. Shipping took for ever. Also the products that said they were in stock wasnt accurate. My amp was on backorder and my deck was discontinued. They informed me 10 days later !! But every other time i had no problems...

Great for the price

For the price you can't beat this 4 gauge wire! Came with everything I needed to hook up my system and everything included is nicely built and quality connections. Delivering 1500 watts rms to my Hifonics 1516 and haven't had any problems at all. Fried my old amp and there wasn't a single problem with any of the wiring after which to me says this is all quality stuff!

By Taylor T on April 21, 2015 Verified purchase

good value

This is a good product. It included everything you needed to hook up your amp. 4 gauge wire is flexible and easy to run through your car. Why spend 100 of dollars when you can get everything you need for the fraction of the price.

Best choice for your money

This wire is a rare breed. It's legit gauge at a much lower price than the flagship brands. Wire was flexible for movement but plenty of wire with a little plastic covering rather than a little wire with a lot of plastic covering. All the essentials for wiring up an amp are in the kit with plenty of wire for my extended cab pickup. Great choice for me at a phenomenal price. I just hooked it up so can't speak to the durability as yet but it looks to be very good.

Great value

This was the perfect upgrade for my system. It has everything you need except for one thing I would have changed about the product is adding another ground terminal. It has the two terminals for the amp but not one for the chassis ground so I had to go online and buy a pack of 4 gauge ring terminals. There's also plenty of speaker wire too! I like the design of all the wires, it's very easy to twine together.

Solid Kit

Solid durable kit with everything needed to get you up and running in one package. I would prefer a simpler fuse, but I'm no pro, and this may be better. The only other area that I would make a change is to add some fork style crimps for 4 guage wire that is small enough to fit the tiny terminals on the amp. Other than that, It is solid and for the price, will more than meet your wiring needs.

Great Bang for the Buck

Good kit for the price. Quality is good. I didn't have any true 4 gauge to compare with, but it is definitely thicker than true 8 gauge. I probably could have done fine with true 8 gauge or 6 gauge, so this kit is overkill.

Wires are nice and flexible and the feeling of the insulator is nice (smooth and soft, as opposed to hard and tough). Could get nicked I suppose, but I haven't had issues so far. You should be using grommets anyhow. Current have just replaced my accessory ground on the vehicle with this and it looks and feels great. I'd recommend this to a friend in second.

Does a fair job

Installation was simple does a good job stops lights from dimming other than that goodbye good price

Not Bad

I will agree, the best part of this kit is the 4g wire, and the RCA's everything else was a let down.

The speaker wire isn't quite 14g, its close but not quite.
The fuse holder will make you want to punch a baby (They don't tell you, but unscrew the allen screws and pull out the metal insert and run your 4g straight into the ends of the fuse holder, as per another manufactures instructions.)
Invest in a hammer crimper tool, or solder the ring connectors.

Basically it works, but there are better kits in the same price range that also offer true 4g wire.

Great quality not so nicely paired

Great quality but this kit was recommend for the 4-channel amp I picked up... I needed 2 sets of RCA cables not just 1. Or at least splitters.. It was a painting go track down a suitable set of RCA cables when your in the middle of an install.

Good

Great inexpensive wiring easy to install, red and black are good colors

Good setup

A little tricky to get the wire into the fuse block but otherwise, painless.

An okay product from an okay manufacturer.

The kit is a great starter kit, but not for the money. The cable is high quality, but CCA, not OFC. The connectors seem cheap, and I can seem them failing in the near future.

okay wire kit

The wire doesn't seem like true 4 gauge to me but it still got the job done for installing my second batt and the wire is very flexible

Everything good except RCAs

Everything in this amp works great except the RCA cables. One of the connectors seems to be damaged internally and causes the music to crackle when moved. It also picks up significantly more noise than the $4 amazon cable I bought that is routed right next to it.

Everything that I needed

The Belva BAK42 contained everything that I needed to install a sub in the back of my SUV. The only problem that I had was that the power wire (4 ga) could have been a little bit longer. The rest of the kit was good to go.

The whole package

I used this kit for an Alpine amp and sub combo and I am very pleased. The cables are very good quality and the kit came with everything required to install from front to back. Very pleased!

Excellent kit! Works great no problems at all!

Bought this kit needing something good on a budget. For $30 you really can't beat it. I wanted to go with the Kicker kit but I couldn't get myself to spend $90 on a kit. So I bought this Belva kit thinking I'll just rewire my car again in the future when I possibly upgrade my amp and add another sub. But so far it's been working really nice! Hasn't melted or heated up. Delivers the power a 4 gauge should. Wires feel quality and not cheap like every other $30 kit out there. I'm very happy with it. It's been 1.5 months now and no problems. Wire is nice and flexible so it was easy to route it through my car and get a nice clean install in my trunk. The kit comes with 17ft and that was just barely enough to wire my Volvo s70 with a capacitor too. So if you have even a medium sized car, you might need to grab an extra foot or two of extra wire. No big deal though. Overall I am very happy and will definitely recommend this product and buy it again if I ever need another kit.

By Jonah on April 7, 2015 Verified purchase

So much better than those cheaper kits.

I've used plenty of discount brands in the past, even some a few bucks more expensive than this one. This is by far the best set I've used!
All cables are very nice. They're flexible unlike their cheaper counterparts. The speaker wires contain a solid amount of wire! Very uncommon.
I can't recommend this enough!

Great !!

This set was great ! Easy to install and had everything ready. I love it

Belva bak42 amp wiring kit

Quirky kit, however they should offer a longer amp cables for larger vehicles.
I have an Armada , battery is on the right. Firewall access is on the left.
The 4awg poistve amp cable was too short, I needed 22'.
Hard to find 4awg that's a fexible braid. Home Depot had 4awg with heavy strands that were too stiff. Had to buy cable in a specialty auto shop.
Best bet if you need longer cable get it a West Marine.
The radio to amp RCA jack cable just made it.

So if you have a compact or regular size vehicle, I'm sure this would work fine for you, just make sure you measure first.

Other than that , it is a great amp wiring kit for the money, and wold recommend.

Bang for your Buck

Holy cow, This kit is way more than I expected!
The quality and craftsmanship put into this is amazing.
I would recommend this kit to anyone who needs a 4 Gauge kit.

Cons: The fuse holder connections are a bit small, But an easy fix is to cut some wire off.

Nice wires

They are good thick wires and deliver good power, haven't had any problems with them and I got them with the amp I bought and sonic gave me 20% of the wires so I got an awesome deal

Not true 4 AWG

Bought this to replace some 8 AWG in my mustang and found that the actual wire inside the insulation was the same size as my 8 AWG that I was already using. Better quality wire than what I had, but not bigger. BEWARE!!!

Not bad

This kit has true 4 guage and flexible wires. It sounds great, however, the ends to the wires are almost impossible to crimp so I had to buy other ones. The fuse is also very hard to hook up.

Great savings

I saved money by purchasing it on line plus free shipping.

belva bak42

Works good so far. Connecter came off power wire but no complaints, ol lady did it.

Good

Good power cable set. The remote wire is way too fragile but i can deal with it. Had everything it needed for me. Perfect size too just barely reached.

everything you need!

Not bad, but the cables are barley long enough to run, extra 3 foot would be great. but figured out a different way! you have to open up connecter to crimp to the power wire, seams to thick for it!

Perfect budget

The 4ga amp it was perfect for my 1000w PPI amp and was surprisingly high quality for the price. I have purchased kits that were two and three times the cost that were made cheaper. I will most likely continue to buy their kits because I was more than happy with the products craftsman ship

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

Just what I needed

It had everything I needed and it sounded great when I was done. I would recommend this to anyone who needs to hook up an amp.

ok

it gets the job done but the outer jacket on the power and ground are to soft and get cut easily and the remote wire is too thin used the speaker wire for the remote rca is probably the only wire i liked but i wouldnt by this product again

best bang for ur buck!

It matches up with what i got n does the job.

beau produit.

belva fait du beau travail.
ressemble aux produits STINGER.
donc très sérieux.

All parts needed are included

Everything you need to install an amp and sub is there. Wires are well made, but the 4 gauge power wire wasn't long enough for my car (2001 pontiac grand prix), but all i needed was a foot which you can get at a hardware store.

Get the job done

Decent wires. Got them installed and everything sounds good. Would recommend.

Perfect Fit!

Works perfectly fine! Plenty of wire length for my 2006 Honda CR-V.

Amp Intallation

the is a good value for what you get. Only wish it had two RCA connection cables

awsome

Its a good in expensive kit. The only thing is I wish it came with more wire end connecters so your choice isnt buy boxes of what you need or just smash the wires under the clamps in the amp. But this is most wire kits good value and product just a wish.

got the job done

Thickness of the wire allow for a lot of durability. not easily crimped though. Good power transfer. The ring terminals and fork terminals look a little cheap.

Belva 4 Guage amp wiring kit

The kit is ok, I had trouble crimping the 4 gauge wire myself. I thought I had it crimped, It just pulled right out. I had to take It, and get It professionally crimped. It's good now. When I say crimped, I mean the o ring metal part that goes to the battery, and the other goes to the amp.

Everything you need

Easy to hook up and install everything, haven't had a single problem and came with everything i needed for my sub and amp.

Just got it in a combo. Nice.

Surprised at the quality of wire and RCAs given I got it included in a bass package with an amp, subs and box. Everything wired up easily and my bass is great so no complaints here. My installer said it is a really good buy too and was surprised that it wasn't like a cheap one that has all plastic and no wire.

True 4 gauge

Recommended to me by someone from Sonic Electronix directly. I had another 4 gauge wiring kit in my cart, but the representative alerted me that it wasn't a "true" 4 gauge wire. He hooked me up with this for the same price and I'm loving it!
Provides enough power to everything, comes with tons of connectors and everything else you need for an install.

A huge pro I found with this wire is that it's very durable, but not super stiff like most wiring kits. The power and ground cables can be bent and formed to curves easily, which made my install SO MUCH EASIER!

Good Wires!

Good set of wires. I like the colors. I also have the 8 gauge kit and they both work great!

Can't Beat the Price

What can I say. You can’t go wrong for the price. Try to buy such a wiring kit at this price locally. Good luck with that one. I’ve purchased several wiring kits through Sonic and will continue to do so. The quality of everything in this kit looks good, most importantly the wire itself. I recommend buying it.

Great amp kit way less than most big box stores

Great wiring kit without spending 90 like at most shops. Comes with all the connectors.

Great Buy

I bought this wiring kit after a employee recommended it to me and let me tell you I am more than pleased. The wire is true 4 gauge and I would recommend this to anyone that needs a solid kit on a budget.

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.

Not a bad value

I purchased this on a budget to install a kicker 400.1 amp. Over all not a bad kit. Installing the power cable in the fuse properly takes a little patience but is doable. The remote wire for the amp seems a little flimsy but the cables are easy to work with. I have used this kit twice and am happy with it. If you are going through the firewall on your installation like I did, I would recommend purchasing a good weather proof 4 gauge bushing.

Best Amp Kit Ive Ever Used

good amp kit this is a true 4 gauge kit i would recommend this product to everyone that is hooking up a system

Good quality!

Almost all amp wiring kits that you find these days feature nothing but cheap, Chinese junk and under spec wire. This one though.. is different. Nice quality, flexible, TRUE to spec 4 AWG wire. Good quality twisted pair RCAs. An actual mini-ANL fuse holder instead of a cheap AGU. Very nice and worth it just for the cable alone! You can't go wrong with this kit. Do it.

bangn

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

Not 4 gauge.

Received this kit and its definitely not 4 gauge. It's at the most 8 gauge. Barely even that. I didn't even use the power or ground wire. I went to advance auto and got some 2 gauge by the foot. I used the rca cables which seem to do the job but are low quality wires. The speaker wire does alright. It's got a thick coating but not much wire. Not impressed at all. But I guess that's what you get for paying 30 bucks. But really don't lie. Just advertise 8 gauge. I

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..

very well put together kit

all the items in this kit where perfect for my install well worth the money

By james on June 9, 2015 Verified purchase

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.

Use to purchase this all the time

Belva brand is good affordable material when starting out but through out time cca corrodes if you have the money buy ofc cable

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!

Terrible wire

It's just cheap wire would not recommend for ise as it breaks very easily, the remote wire is almost unusable

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.

Does it's job

The power should be 20' and ground should be a foot longer but other than that this is a good kit. Does what it's supposed to and is as the specs say.

By Anthony on August 16, 2015 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!

Good extra fine wire

This is excellent speaker wire. One wire has round insulation while the other has square insulation making it easy to identify hot and grounds. My only installation problem was I didn't order enough. I needed a quantity of 2 just to wire a single cab pickup.

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.

Good wire

This wire is great speaker wire. I like the way it looks and works great.

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!!!!

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.

Excellent value

The speaker wire is a good price for the length and gauge.

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

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!

This kit is just fine

It might not be "oxygen free pure copper" but as always, don't expect $300 quality for $30. I'm using it with a 500 watt Rockford amp and it's great. Good complete kit too. For the record, it's twice the quality of anything you'll get for this price off the shelf somewhere.

Great price point for a great product. Everything worked perfectly

Good kit

Good kit with standard cables and length. Fuse seems to be good quality and cable isnt bright so it blends better in engine bay and trunk. Was included with a JBL sub and amp kit.

well worth the money !

The belva bak42. Amplifier wiring kit is a great value for the money " the fuse holder is well made " looks nice an the kit includes everything you need to do the job " it even has a firewall grommet " the wire is very flexible an easy to work with " all in all a very nice kit so go ahead a grab yours " you will be glad you did !

Great product....Great price!

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

Wire to short of full size SUV

I own 2012 gmc Acadia and this wiring is to short. If you have full size SUV I would recommend getting longer wires. Power and ground were OK because battery is behind passenger seat not under hood of car. RCA and remote wire had to be extended.

Not bad

I didn't care for the fact that the set did not include enough connectors for the entire project. Since the kit includes a Cap you would think the kit would take this into consideration.
I guess you get what you pay for

Works as said

Great little kit works just fine. Was a fill in till I could afford the nvx 0/1ga dual amp kit to clean up my wiring. Nice thick ca wire. Better than most other cca wiring kits heavier wire and better quality. More copper it looks like.

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

4 ga amp kit - Belva BAK42

Let's start with the basics:
The primary power and ground wire seem to be of good quality
The RCA cables I have used before and they seem to be of decent quality
The fuse holder with the mini ANL fuse - a little difficult to work with but of good quality.
The remote wire included in the kit - total garbage. Throw it away and don't bother running it and wasting your time. Ended up rerunning a remote wire that was a true 18ga and better quality. Anything you did to this remote wire would break it.

Great, all-inclusive Amp wiring kit

I didn't have any/enough battery cable lying around, so I decided to pick up this kit rather than buying components separately, and definitely can say I was not disappointed.

High quality power/ground wires, speaker wires and even the remote wire (a usual failing of wiring kits like this is a cheap/fragile remote wire). The RCAs are nicely constructed too, as is the fuse/holder. And quite honestly, everything looks nice to boot.

All of that for a great price. No complaints here at all!

Reliable Amplifier Install Kit

I've used these Belva BAK42 kits for installs on 3 separate occasions, and they always seem to do the job, and hold up very well over time. Be careful with the in-line fuse, as it is quite fragile. Also the included wire intended for the remote input is junk, do yourself a favor and just use speaker wire or something of better quality as the included wire will strip right out with the insulation. Overall reliable and will get the job done.

Fantastic Sub Box

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

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

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

Sturdy enclosure

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

Best Value!

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

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

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

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

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

Very Happy!

I have a Power Acoustik MOFO-122X (2700w 1500RMS) 12" sub hooked up to it running a 1ohms and it never shuts off. Also it ran with no problems in -15F weather.

Great Amp

for under $100, this amp is a solid buy. it's 1 ohm stable and pounds my mismatch subs. i have it turned up 3/4 and bass boost is up all of the way @ 1 ohm. the bass remote is extremely precise, more so than the more expensive brands. it only gets warm @ 1 ohm, cold at 2 ohms and freezing @ 4 ohms. it does suck major voltage and i would recommend a second battery or extremely good cap. i currently have a 2 farad cap and my voltage drops to 10.9 volts sometimes. my lights dim. my alt is rated at 145 amps and charges at 14.2 to 14.7 volts. i mention this because i had doubts about it's power output. looking at my lights and volt meter, i no longer have any doubt about it's power output. i took a chance and it paid off. i wanted to feel it in my chest, now the ground feels it. my Yukon is on another level with this amp. i might have to get new subs soon :)

Amazing for the money

This amp is one of the best amps I've had I was scared at first to buy it bc it's a boss and when you think of boss it's not very good stuff but this amp is so amazing it pushes my one 12" at 2ohm so good it flexes my sunroom,front windshield,doors,mirror ever moves my hair it's truely a good amp for the money I'm sure there's amps that are better but if your looking for a cheap amp that will push your subwoofer good I highly recommend this amp

Great amp and cheap

Very good amp for 100 bucks shipping was very fast I order it on Monday had it Wednesday

Boss R3400

I was a little hesitant in buying this amp because I read that someone had one and it overheated. I read other reviews and decided to go with it and for the last month I'm glad I did. I have it hooked up to a Alpine 10in R type and it does what I want it to do and my daughter loves it also

Bullet proof amp

Have two Boss 3400s slaved on a pair of comp Soundstream 15s tuned to 34Hz with 6" aeroport. Gain on master amp about half way. Have them in a Toyota RAV4. Windshield flex as well as rear doors and rear hatch. Can get downright painfull on some music. Amps running on 2ohm load and never have a problem delivering. You can spend as much money as you want on a much more expensive amp, but for what these can actually do, there's no need to.

awsome

sonic did it again . we love them

Works great!

I bought this amp to run two 10" DVC 200W rms Cadence subs wired to run at 2 ohms, housed in a downfiring box in a Jeep Wrangler. Amp never gets hot, drives the subs perfectly with nice clean sound. Very happy!

great amp for the price

Better than I expected. Would recommend it to anyone on a budget. Thinking about getting another one

Great budget amp

For the money it's a great amp that I would recommend to anyone. I ran this amp for a few weeks and passed it down to my wife. I bought a Orion amp to take the 3400 watts place. Boss is a good amp. Orion is a great amp!

Boss R3400D

I got this amp as part of a Sonic Electronix bundle when I was 16-- it finally blew and I'm 24 years old! For a low budget amp this thing puts out some serious power with some serious durability. This was in a convertible mustang, an X-terra, and a jeep wrangler with at least 3 different woofer setups paired with it over the course of its life, and I couldn't be more impressed. It saw long term sun exposure, off-road dust, clipped wires, corroded grounds, and plenty more without a hiccup. This last Montana winter finally kicked its butt though! My only complaint is that the sound quality wasn't comparable to higher quality brands, but you get what you pay for... and then some with this one! Would highly recommend to a beginner or someone hard on their amps.

Great amp for the money

This Boss amp is great for the money. I'm using it on one 12" and it does great and has never had any problems. I would recommend it to someone not looking to spend too much but wants some good power.

fried in 11 days

one alpine 10type R at 4ohms. figured i would run it at 4 ohms, not to use all the power the amp can give, to be safe. sounded great, hit hard, then 11 days later amp started switching back and forth from protect to good, green red green red green red. amp will not recover from this limbo state..in the amps defense, i did have the level all the way up,and was listening to Knife Party..maybe i was pushing it too hard? amp is prlly good for a basic 150w rms sub. i would recommend spending more for a well known amp if you're tryin to power an 800rms dvc sub. just bought a Belva, sounds and hits 3 times better.

Boss Auto Amplifier

This item is truly outstanding. The price was excellent, it arrived in good time, great packaging, unfortunately UPS delivered to the wrong address, but they brought it to us. We had it installed professionally and it is working outstanding. It was installed on the back side of a fold-down back seat, which makes it easy to get to and allows for plenty of air space for cooling. Great product works excellent with two 12" sub-woofers.

Great for my setup

Using this amp for Bass. So far so good. I dont think it really puts out the power it claims but passes for clean crisp moderate bass. Bigger magnet speakers will absorb this amp.

Pleasantly surprised

Wow, this boss amp really pushes my 2 15" kickers subs like crazy. I am very surprised people always giving, boss brand a hardtime but, WOW! THIS AMPLIFIER IS REALLY OUTDOING ITSELF AND DOESN'T GET OVERHEATED.
