Customer Ratings & Reviews

BAK 82

Nice package, quality wire but could more end connectors for the larger wire.

Good product

It's exactly what you need for your car amp installation. I bought this kit with Kenwood KAC-1502S amp for 75 bucks. Good deal from Sonic Electronix.

Great kit for the cost

Very nice kit for $18.
Wire seems adequately thick. Good quality fuse (not AGU) and fuse holder. RCA's feel durable. Decent assortment of accessories. All together a solid budget kit IMO.

Don't know what the other guy is talking about.

This kit was awesome and included with my package that I bought. In comparison to others for the same price, there is simply not a comparison and the other review is just wrong on so many levels I felt compelled to write this.

The reality is there are a lot of real shoddy amp kits and wire as a whole being used in car audio in terms of cheap amp kits that have over-insulating wires and fake gauge ratings, huge amounts of aluminum, lousy RCA cables, fuse holders and other accessories. BUT and a BIG BUT, this kit excels in those areas where others fall flat on their face. I have bought a few inexpensive 8 gauge kits in my day and XScorpion, Raptor, Install Bay and others haven't even given me the 8 gauge of wire that I paid for, and in some cases gave me wire that heated up to a dangerous level due to the actual make up of the wire.

I also literally laughed when I see that the other reviewer was intending to use spade terminals to connect his amp power and ground wire... It is for the SPEAKER wire knucklehead :-). I am an installer and the smaller accessories work just fine when you use them correctly. Most amps will still work with them when used with the speaker wire. Of course one can be used for the remote wire connection to the amp and the other end with the butt connector being used to connect to the stereo. The funny thing is, if you do not need them, who cares? It is like ordering this kit for a compact car or single cab pickup. You will not use all of the power wire for these applications, so do you complain that the manufacturer gave you extra wire? That just made me laugh.

Now, onto the other accessories. The AFS fuse and holder that are included are so far superior to others in this price range and the amount of copper (albeit CCA) is much better than others in the price range. Lastly, the RCAs included are awesome for the price. I cannot find ANYTHING to complain about here for $21.99.

All in all, you will not get a better value for the money.

Good product for the price

Good wiring package, good quality fuse holder and wires, I would like more connectors on it and maybe some tube for the power wire, but overall is a good kit.

Good Purchase

I used this kit to install a 2 channel Boss amp. The quality of the pieces in this kit is five stars, but I'm giving it 4 because it is my belief that to do a clean install you need (4) 8 gauge terminals (one at the batt, one at the amp, one at ground, one at the amp), not just two. I had to spend an extra six bucks at Orchard for the extra terminals, but since the cost of the kit here at Sonic was only $20 at the time, it was still a good deal.

Good kit

Good kit for basic setups. Using it right now in my mothers system powering a simple 12. Could handle more if needed.

Pros: Handles power, Wires are HQ, More copper than rubber, Wires are good length, Fuse is HQ, Comes with lots of ties and rubbers.

Cons: None

I would recommend this kit to anyone who has a simple system. All around good kit.

Great wiring kit

works great on my MB Quart 2x100 watt amp.

Good Kit

Great kit for the price. the price is good. Long wires.

Belva BAK82

Worked very well for the money, great value for my system! Only thing that kept me from giving this 5 stars across the board is the design of the fuse holder and how you have to change/connect the fuse, minimal complaint.

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:)

good

Pretty well made box. The sub hole was a little too small for my 12" hcca but a little cutting solved that. I didn't have time to make my own box so this suited me realyl well.

good product

Sound really good and looks good. Made fairly good. Would for sure recommend

Very very nice, exact specs below.

Very nice box. The carpet is nice and seems to be glued properly, although it does look like it might rub off in time. Build quality is very nice, feels very sturdy. There are some globs of dried glue on the exterior but nothing I can't get over. It would have been nice to not have the sub cutout so close to the port but that's just nitpicking. Doesn't come with wires internally but the terminals are much nicer than I've seen on other prefab boxes.
Regardless of what Belva has published, this box is not 1.8 ft.

The gross volume is 1.97 ft, but after taking into account port displacement, it's net volume is 1.30 ft. It's also tuned to 34.4 Hz. Determined using the Torres Speaker Box Calculator.

well built box

For the price it cannot be beat. This box meets the recommended size enclosure for the single sub i ordered, which is the Rockford P2D4. Ported to trick the sub its in a bigger box with poly fill lining. Well built and carpeted in dark gray. I highly recommend it. Hits lows hard and loud.

Not bad

So I bought one of the "Sonic Boxes" a couple years back and it was similar to this box but gray. The sonic box was better build quality. This box has a hole cut that is nowhere near center. It's up and to the right a bit, but that's what you get for a 55 dollar box I guess. The carpet around the ported has started to come unglued and the box hasn't had any play time what so ever. It seems to be mdf and 3/4". The dimensions are correct. Port tune is around 35 hz and net box size is around 1.4 cubic ft. The poly fill probably needs to be glued down so I will stay inside the box. The port used to be rounded on the inside with the sonic box now it is not. It is a good box to get by on since it is built pretty well, but I would recommend getting a box built to spec for the woofer you have for optimal sound. For 55 bucks it's not a bad way to get by, just don't expect the best for that price point.

Great Prefab box

I would highly recommend this box it sounds like it is tuned between 34-36hz hits lows really good unlike i was expecting since it is vented. I had a rockford fosgate p3 and it sounded amazing in the box and now I have an Alpine type S in there until my new p3 comes back in and the type s even sounds great i didnt think a type s would pound like it did. Good box would def recommend and buy again if need be.

nice sound

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

great wiring package

Great wiring package for the price, everything you need is included. Sonic has the best prices that I could find anywhere.

Great product

Slim and powerful speaker that packs massive power for a great price.

Worth it

This one is good try the four gauge amp kit

Worth the space

I downgraded from a much larger box to this one and noticed no difference. Saved me some space, though it's still pretty big, and handles the sub perfectly. Feels sturdy and looks good.

Awesome box

This box sounds great coupled with a Pioneer Champion Series Pro and 1500 watt amp. Very deep bass tones and very loud. Definitely would recommend.

Price is right

This wiring kit is very good quality. Although this was my first subwoofer install, I consider myself an expert when it come any kind of stereo hookup. This kit comes with everything you will need for a professional install. I installed a MTX self contained in the rear of my 1999 Explorer Sport. This kit made eazy.

Exactly what you need

Comes with everything you need, literally. Ring terminals are good quality, insulation is very good quality on the wires, fuse is good quality, currently connected 2x 600 watt Pioneer 6x9 speakers to a 450 watt amp (250RMS) with this wiring kit. Plenty of length to get from the battery to the back of my car. For 21$ this is a steal! Does its job, does it well. Highly recommend this, you won't beat this price for everything you get.

get's the job done

This amp wiring kit did the job. Fortunately there was just enough wire to make it from the trunk to the battery in our honda civic sedan. A larger vehicle may have been a problem. The kit came with almost everything I need to install a self powered subwoofer/ amp.

Belva BAK82

The quality is good and everything I needed was there. All of the fittings were good. More than I needed. I would recommend this product because it delivers as claimed.

Belva

This cost more then the gray one but they both perform the same just that the black exterior looks way better then the gray

Cheap - And it is

The wire is fine, the RCA cables are fine, but the terminals they give you are worthless, not enough of the 8GA size for both ends of the wire, and there are a bunch of small ones that werent even needed.

Excellent product for the price

I'm not running a sub or crazy rms wattage. This kit is more than adequate for my set up. 60 watt rms fronts and 80 watt rms rear speakers. The amp is 75watt rms X4. I would definitely buy this kit again for any similar set up. Plenty of length for all wires except the ground. If you are mounting the amp to the back of your rear seat and it folds down, make sure the ground is connected as close as possible the seat. Other wise the wire will prevent the seat from going all the way down. Wasn't paying attention to this. Bent the ground terminal on the amp when I folded the seat down and it hung up on the ground wire.

Cheap and does the trick.

I bought this for my gf trying to save money, it handles power fine and doesn't distort. Very happy.

good quality

Used it in my truck for a small amp came quick and easy to use would recommend it for anything from daily to comp use

easy as

Bought this kit with the Pioneer TS-SWX251 sub/enclosure and the Kenwood KAC-1502S amp it includes more than enough cabling to run the length of the car and looks to be good quality cables.

Good deal for the price

this wiring kit comes with all of the nessary components to put in a small amplifier. great value.

Belva install kit 900 Watts

look like quality wires nice and heavy!! more rubber coted than plastic may last longer??

amp kit

Nice amp kit for the money. I have used this kit on about 4 installs and will keep using it.

Came free with Kenwood amp, works fine.

This wiring kit was included for free with my Kenwood KAC-1502S amp that I use bridged to drive my Pioneer TS-SWX251 sub. It is a decent kit. The speaker/power wires are copper-coated aluminum which is just so-so. But it does include everything I needed to wire up my amp (fuse kit, zip ties, wire terminals, etc) and it works totally fine and I doubt I'll ever have a problem with it. So while theorhetically the wires could be higher quality, practically speaking I doubt I could ever tell.

did the job

Had all the wiring needed and a little more. wiring feels flimsy but it works !!

Great wires a pain to cut

The length of all the wires was perfect for my VW gti to set up an amp. However they are a pain to cute and strip. The rubber coating is very stretchy. But they work great. I do recommend these for the price. The connectors for the ground and power wire are crap. They do not like to stay though. Once you get it then they are good.

Great

Greatest box I've owned sounds great in a smaller car I had it in a bigger car and would have needed two to get the bass I wanted outta them but then I bought a ford fiesta and it's smaller so it sound great and is perfect for my little car

Good enough

Overall, this is a decent enough kit for an amp install. Fairly run-of-the-mill kit - my main gripe is that some of the prong connectors are incorrectly sized (amp connection for ground and power wire), but all other connectors are good. Zip-ties are garbage, but that's pretty much expected as well.

great boxes

Great construction. Good solid connections for your speaker.If I needed another one. I would look no further.

Wiring 101

Pretty basic kit, I would recommend it but based on my application I needed some larger capacity connectors than what were provided.

Boa qualidade

Muito boa qualidade, e muito barato vale a pena, a qualidade é incrível

It Works!

Everything worked as it should and this kit had lots of wire to get the job done!

Install Kit

Very impressed with this kit, had everything I needed for a clean install. Glad I purchased it.

Nice Box

This box will definitely help the RIGHT sub put out some serious bass.

Great strong box

Great box, solid construction, easy set up. I personally prefer an exterior terminal connection that is a push type, but this screw type works just fine. I highly recommend.

Solid for a cheap option

I used this with a JL Audio 12WX sub powered off a Polk Audio amp giving it 200 rms. The box produced great output considering the entry level power and for a non-audiophile the clarity will be fine. Yes, a custom made box is ideal but if that's not an option for you then this is a suitable alternative.

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

Good Product

This kit seemed to me to be a good value kit. I felt that the connectors and one of the cables was of a cheaper grade than what I would prefer. But I feel that it was priced accordingly. The product met my needs, except for me using a better quality crimp-on connectors.

AWESOME BOX!!!

I dropped my Fosgate P3 into this box and HOLY CRAP!!! I had this sub in a sealed for a while and thought it was loud.....but now its insane!!!! LOUDER THAN HELL! GET THIS BOX IF YOU HAVE a TYPE R OR P3!!

Great Box

I bought this for my RE sex sub and sounds perfect. my sub is a 12in sub but i had to get the sub cut out widened. Local car audio place did it for free.

BEST BOX EVER

MY MUSIC IS SO LOUD NOW. I LOVE IT!! NO ONE LIKES TO SIT IN THERE WITH THE VOLUME UP. ITS AWESOME! AND SONICELECTRONICS GOT IT TO ME IN A TIMELY MANNER! THANKS!!! CARPET IS GREAT! PERFECT SIZE TOO! I HAVE A SWR12D2 ALPINE TYPE R. JUST ONE!

Perfect Specs for JL 12W3V3 Ported Enclosure

I searched for a decent sub enclosure that would match the JL Audio specifications for the 12W3V3 in a ported enclosure.
This sonic sub box was a near perfect match for specified enclosure volume (1.7 cuft) and port tuned frequency (31 HZ, after measuring the port size, length and using online calculators).
Shipping was a little expensive (30.00) but it arrived in a day and 1/2. The box is solid and well constructed- not perfect- it has a hand built appearance- but it is sufficient.
The JL sub fit in the opening with no issue. The terminals are light duty but also sufficient.
After much research and deliberation, I did add some layers of poly fill batting to the walls of the enclosure's interior. I bought some pre-cut 1" thick pads from the fabric store- they were sold as baby crib side cushion padding. I put one layer on the top, bottom and left and right sides, being careful not to obstruct or block the entrance to the port slot. I put two layers on the wall directly behind the woofer. now the woofer back wave sees a group of nicely padded walls.
Again, after reading the pros and cons of doing this with a ported enclosure, I took a chance and did it before listening to the speaker- I wanted to get it right the first time I put it together. I had a hard time with envisioning running the sub with no padding on the interior walls.
The results are paying off- I seem to have plenty of output from the 12W3, and it is absolutely tight and deep when compared to other ported subs I have heard, and there is zero unwanted port noise- and no muddiness or booming.
The sound is right on the money- absolutely perfect and exceeded my expectations.
My only issue is the size of the enclosure- it takes up about a third of my small SUV's cargo area.
In the future I may try to find a much smaller enclosure and go sealed, about a third less volume than the JL specs for sealed, and maximize the volume with a complete polyfill stuffing and see what that sounds like. Maybe not though, this one sounds like a winner with the JL 12 W3 and it isn't even broken in yet!

Best box I've ever bought

I can't believe I didn't know about his website before now.. This box was worth every penny I spent... Great quality and amazing support when I had questions.. Will definitely be ordering from them again

Banging

Good box for the money. Sounds great!! Feels durable. Nothing to complaint about. Always been the vented type guy.

great buy

Its a wonderful box, I'm enjoying it right now, it sounds good in my Honda Accord.

Awesome box, BUT DON'T buy thinking your going to hit low notes

Really good box but don't buy thinking you are going to hit the low notes. Way better then sealed!!!

All i can say is WOW

Well, i bought this box with a 12" rockford t2d2 to place in it. I noticed this box was around 40 pounds and my sub was around 70 pounds.

I was a bit skeptical at first when i placed it in, thinking the box would break. I have been pounding the living hell out of that sub and it has sounded clean, loud, and incredible... Perfect amount of air space, 1.8 cubes.

Def would recommend this to anyone...

nice enclosure

This was a very good enclosure not cheap made at all I got a jl w3 12" in it and it sounds very good better than my 2 12 inch pioneer in a seal box

Great value

I bought this boxes wondering what it would sound like I put my candy red audio pipe in that box Ty really gave my the boom i was looking for overall great box i would recommend it

nice box

Nice box,good bass tones,Great price,thinking about getting another for the car,

Just got it all installed, love it.

Pros, loud as hell! Cons, its a really deep box. Got the Boss phantom subwoofer installed into this box, and couldnt be happier! I only just got it installed, but so far, it's been unbelievably loud. Recommend it for sure.

Worth the price for the convenience.

Made installation a snap without having to build something. Sounds great.

It is a good box

It is a really good box the only problem i have is with the terminals and the terminal cup. For one thing you might want to put some silicone around the inside to seal it off and the other thing is that the terminal nuts get lose and the terminals touched each other and blew out my sub. So if u buy this box make sure that the nut are TIGHT!!!! If not it will losen up and the terminals could touch and blow your sub.

nice

Pretty good box mine was broke but it was probably a rare instance

Belva 1SV12B

This box is well vented.. Made professionally, looks nice, and bumps HARD with my Rockford Fosgate sub. It pounds the hell out of my big car. Fantastic and well worth the money.

Great Value!

I ordered these items for my grandson, to go along with other items. He loves the system.

good deal

everything you need is in this kit and for me there was more then what i needed.

Sonic Sub Box: 1SV12

Forget for a moment the price. The house system has a separate low end amp as such powered base cubes were not considered. (These became parts of a replacement).
Loaded with Fosgate P2s they work excelent.
Modifications:
Egg crate foam added inside except for port area.
1.5" wooden feet added for appearance and getting the cone area out of vacuum cleaner "range".
Suggestions.
Although the price was great I would gladly have gone a few more bucks for wood venear.
Down firing seam to be better. Would be nice if ther were that version even if somewhat larger. Size increase depending on driver characteristics.

All in all................
Good price and low hassle. The best recommendation is they need be heard, or do I mean felt.

Best box for Alpine Type R

I saw a lot of other boxes for all around the same price and the reviews were so mixed. A buddy of mine has two type r's in the basic Alpine boxes and it doesn't come close to how loud these boxes are. Personally, the 3/4" MDF/polyfil combo produces a much deeper, better bass than all of the other boxes. GET THIS BOX IF FOR TYPE E/X/R or any subwoofer that it fits the Ported Enclosure Volume range!

It is 27 December 2014 and I installed my Type R in this box with an Orion CO2400.1D amp and SoundQuest 2F Capacitor around Thanksgiving of 2014. It sounds amazing!

enclosure

for what it is the enclosure is well built and worht the cost. but for the application it ws recomended for its acctually to small. way to small for the sub but still worth the money if nothing elese for the quality of the build.

perfect kit

Made the install happen much faster. Everything was easy to work with . Very good quality. Real happy

This box works well

Paired with an alpine type r it works very well and adds much boom to my system I have no issues with this box at all not a custom but solid sounds good and much More easy to come by if you don't have time or restores to build your own, before this box my bass was loud after this box my bass was a bomb

Great!

Ive had no problems with this box.

pretty solid

I had a 12" Alpine Type X in this box. For the first year it slapped pretty hard and I had no complaints about the level of sound it would put out. I would be pleased but after a little more than a year my sub ripped the faceplate off of the box, or whatever u call the wood that the sub attaches too. All in all, this box would be great for a sub that is around the 500 RMS range, just be careful with big subs.

sturdy but bad port design

I put a alpine type r in this in my 2000 ram ext. Cab on the back seat and I can hear air rushing through the port I wish I would have went with a sealed box and the hole was off center this box would be good for a trunk of a car

Boyfriend Loves this box.

I purchased this box for my boyfriends Xmas present. He absolutely loves it. It's built strong, good insulation, love the look and overall it makes a speaker sound wonderful. His Planet Audio sounds 10x better than it ever has. Only complaint was the wiring area. Complicated to wire through so we ran them trough the port. Just as easy works just as well.

Well built

I purchased this box for a 12' kicker cvx. First of all this box was built well and very sturdy. However, the sub I installed needed a little more air space. I would recommend this box for any subwoofer under 600 watts.

Best Sound Quality

"BEST" Box ever. I have a JL Audio 12W7 on JL Audio 1000.1 and this sub hits HARD. MY friend asked why my sub hits harder then his 2 12" Audiobahn Immortals. I Would RECOMMEND this box for serious Bass

Nicely built, sounds great.

The box is very nice. It has polyfill in it, the polyfill is not secured very well it is probably best to go through and glue it down, and is built very nicely. The box will (more than likely) splinter when you try to screw holes into it but its MDF and that's what MDF does. It sounds great with an Orion XTR PRO 12 4 in it and hits lows very nicely.

I would definitely recommend to anyone who was looking for a relatively cheap but nicely built box.

Great Box

Would definitely recommend this box. Put a Fosgate T1 in this box and it sounds really great. Didn't think it would have enough volume for the sub but it is awesome. One of the cons when I received the box the carpet was comin off on one side, but nothing some good old adhesive spray can't fix.

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.

Cut out (inches) was not accurate

I used this box with an RE REX 12" and the hole was not big enough. I'm too lazy to go back and dig up my measurements, but the hole was a tad bit smaller than advertise.

Decent kit

This is a decent kit for a budget stereo system. Only one issue though, I was hooking this up in a Ford expedition and wires were too short to put the amp were I wanted it. Will pay more attention to wire length next time.

Awesome box for the price

Great price. This box is constructed well and looks great. I put a CVR12 in this box and it sounds a lot better than my old small sealed box setup. I would definitely recommend this box.

Um Yeah !!!!

If your questioning the quality of this enclosure. Question No More. It is built sturdy, solid (not dry) MDF, all corners are properly sealed, last but not least they even took the extra step in making the Tuned Port Wall with a Rounded Edge!!!! I don't care who you are thats A GREAT DEAL!!!!

Perfect for the EARTHQUAKE SOUND Tremor -X124
P.S Remove the Terminal Box and throw a bead of silicone around it. It will eventually allow air to escape.

Great bang for buck

Had this box with an RE Audio SEX, sounded great for a week while breaking it in then speaker fell apart lol. Now I got a Sundown SA12 and this thing slaps. Very nice for a prefab, can't beat the price. But shipping could have been better. Speaker wire terminals could be better also, but whatever it works.

Great box

I put my Pioneer TS-W309S4 sub in here and it sounds fantastic. Just as good and clear as my friend's 15. This box was relativly inexpensive and is quite sturdy. It looks great as well. The only con would be there is i tiny chunck of carpet missing on the port, it seems like they made it quickly. Either way, this is great box, you should buy it.

Good wire

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

Good vaulue

I have type r in it . Works for me

Good tasty box

Great box. Have it with a 500 rms watt Alpine type r sub and an alpine mrp 500 amp. Sounds great in my jeep patriot suv. I bought some bananas clips in order to remove it with ease when i needed cargo space and mounted my amp in the spare tire compartment. I would recommened this sweet box to anybody.

cost the same as 3/4

This box was way more than I expected for twice the price. Shipped very fast and the carpet looks nice. Had a alpine R type in a 1cu ft box sealed that I was very disappointed in. I was gonna stash it in a corner till the end of time but I saw this box and come on 35 bucks. Pdx 1.600..........R type.........this box.........= loud clear and hits all those bass notes that you know should be there. We all have our two favorite CD's that we turn to every time you turn on a new system. Anyway my cousin is now gonna get two of them and why he wants it that ear splitting loud is way beyond me. Or is it?

Excellent value

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

Absolutely Great!

These are good quality boxes with tons of space for larger subs! Have 2 of these and each one has a RE Audio SEx V2 in it. Although I had to sand the edges of the boxes to fit those monsters in they hold up to the test and make them both sound really good! Love the black carpeting and its probably weird but these things smell great! Definitely recommend these boxes

By Taylor T on April 21, 2015 Verified purchase

Nice and inexpensive

Good little amp kit for the money. Wires are flexible and it comes with everything you need to get an amp going.

By Kenneth on August 13, 2015 Verified purchase

Good starter kit.

This wiring kit is good enough for the basics if you don't want to spend more money or chase around assembling the wires you need for a basic system hookup.

Excellentt

Product is real good and have used for more than 6 months still working really good.

Well Built, As Advertised

This kit was included with a MTX package that I ordered. It was as described and is a well made wiring kit. Installation was quite easy and delivers adequate power to my system with proper grounding.

My only complain, I drive a 1997 Buick Park Avenue, and the 17' of cable for the power line wasn't nearly long enough for my installation. As my amplifier is currently mounted in my trunk due to limited options for locating it elsewhere, I had to go to a local electronics store and purchase another length of 8ga wire, an in line fuse block to splice the connection, as well as an additional fuse to ensure the line is properly protected.

For those of you will small cars, or who chose to mount the amplifier somewhere in the cab of the vehicle, this will be more than adequate. For those with larger cars, or luxury vehicles who are mounting their amplifier on the box or in their trunk, be advised you will need more power cable.

By Jeromy on July 23, 2016 Verified purchase

Good Product

Good Product it could be better if it included ground , power , and turn on connectors for better connection to amp.

By Jency on January 17, 2016 Verified purchase

GREAT VALUE

I WOULD RECOMMEND THIS PRODUCT NICE BOX WELL MADE FIVE STARS

you get what u pay for

Do not try to put a sub that can handle a ton of watts in this box. I have an re. xxx12 and blew the joints out of this thing...other than that I'm sure it is good for subs putting out less than 1000 watts...

Gets It Done

I like this box. It's simple, plain, sharp and clean. It was just what I needed. I have a Type R in mine, and it's wonderful. Does its job well.

Great place to buy

Awesome system easy to set up and ridiculously cheap! I love it

Great box!

This box looks and sounds amazing! Its so loud and definatly worth it at this price!

By Andrew on June 12, 2015 Verified purchase

Awesome Value

I bought this to hook up amp, everything I needed came with this kit
Worked great!!!

Came with bundle rated too high for these cables

I bought a bundle that included these cables (1kw) along with an amp (1.5kw) and 2 subs (1.3kw). Didn't make sense to include these cables, since their recommended throughput is much lower than the other components, so I never used them. They look nice, though.

By Ken on April 19, 2018 Verified purchase

Good deal for the price!

Kit has what it says. Most of the wires are of good quality, but the remote wire could have been a tad thicker. It broke every time I tried to attach it to anything. I ended up using some leftover speaker wire to complete the job. Overall though, you can't beat the value.

By stormyknight on September 8, 2016 Verified purchase

Great Price

This amp kit works as needed, it has everything needed for a basic amp install, I would recommend it for anyone needing a lower priced kit. Just make sure you get the correct gauge wire kit for your install.

By Chad on February 17, 2020 Verified purchase

2nd Kit I have Purchased, Still Can't Find a Better Deal

I had a 500 Watt amp and sub installed in my old car, and sold it with most of the wiring in it for the new owner.
I installed a new 500 watt amp in my new car with a new sub, and bought this same wiring kit as I still could not find a better deal anywhere else.
It's a simple kit, has everything you need, and makes installation of an amp/sub a breeze. Tonnes of wire length, I still have lots leftover thanks to a trunk-mounted battery. My previous car had a battery in the hood, and this kit still have plenty of length.
The RCA's are very nice, and all insulation is great quality especially for the power/ground. Ring terminals are easy to crimp, and were the perfect size for my battery terminals/main grounding junction.

By Vincent on March 6, 2016 Verified purchase

Everything you need

This is a basic kit that has everything you need and is pretty straight forward. No issues so far for the price who can complain

Outstanding kit

Loved it. Nice flexible kit. Good clean power! I would buy again soon.

By Sound dogg on November 8, 2020 Verified purchase

Great product for price!

Plenty of wire, all connectors were there. The flexible wire makes running it easy.

Great product

The product comes packed with polyfill sheets which I didn’t expect (though it’s probably in the description). The wood is cut at sharp angles which is expected but the carpeting is very thin which I wasn’t a huge fan of. I also have a B-Box and it had thicker carpeting giving it a much better feel. The terminals are nicer than expected, accepting banana-type connections as well as screwing down on the ends if you don’t have banana connectors.

Good Quality

Very good quality items in this package. Thicker than average insulation on all wires. Well worth the price.

12" MDF slot port box

Great sounding box!! Strong 3/4" mdf construction. Deep bass and the added polyfill is a great touch. Best box for your money

Great product!!

I like the products i ordered because they are tough wires and high quality

Very Nice Kit

Sonic recommended this kit online to use when I bought a Kenwood Amp. At the time this kit was on sale at 50% off. Glad they did. It would have cost me much more to buy the wire and connectors and fuse separately. It came with plenty of everything to hook up my Amp.
Thanks Sonic!

big black box

sound awesome with my 12" nvx speaker my truck now shake. the box was build with 3/4 wood very nicely make.

Belva Vented Woofer Enclosure

My NVX VCW 122 fit with ease in this enclosure. The enclosure has a nice black carpet covering it and has polyfill to really bring your woofer to life. Not to mention this enclosure survived a hard wreck due to a drunk driver hitting my tail end. It currently is dinged on the exterior a little but works phenomenally.

Amp kit

I have bought different amp kits from other brands and wasn't satisfied with there products because of certain things.1 was price and 2 was the power amp wire where the fuse goes. The plastic part where the amp goes was crap and fell apart over time. I like the sonics amp kit because of both awesome quality wire amp the red power amp wire was awesome quality as well. I would recommend this product to anyone who buys this!

Well built, excellent value

I was surprised of the quality of these sub boxes when they arrived. For the money, I doubt you could do better and I've purchase other similar boxes at twice the price that don't measure up to these. The acoustical damping material is also a bonus, although it would be nice to have a little more "stuffing" for better damping. But you can always add some fiberglas insulation if needed. I will be using these again. The only other suggestions would be to add another small cutout hole for the additional of a tweeter, which is what I did on 8 of these. I am not using the box as a subwoofer, but a two way full range system and Eminence drivers.

Great box!

The boxes are very well built and priced very well.

Very pleased, appears to be very solid!

Overall very pleased, especially at this price point. The box is solid and installing the sub went perfectly as planned. She’s heavy, and big, but boy oh boy does she boom!!

Single 12" Vented MDF Subwoofer Enclosure (Belva 1SV12B)

I like this box. great box for the money if your on a budget like I am. it bangs really hard for what it is. it's not really good for the low low freqs but for the mid lows it does its job well! I get compliments everywhere I go. it gives me a lot of trunk space. which is a must have for me

Would recommend it if your going for something small & space saving..

Bang for Buck

This box is simple, nice, and it works. For the time it would have taken me to build a box this was a no brainer. I would recommend it to a friend.

By Briggs on February 18, 2020 Verified purchase

Solid investment. worth the money

This is a great subwoofer box for someone looking to add some decent low in punch to their system. I used it with a kenwood kfc 12 (400 rms) sub and it works really well. The tuning of this box is lower than most in this price range. Polyfil is a added bonus. This is for standard 12 subs. Would not use for anything serious (800+ rms) as the box will easily start to fall apart.
This does not mean its a bad or cheap box. Its just not designed for higher spl type subs.

Great box

Good sound can't beat the price for this box
I would buy again and recommend it to others

Bang for Buck

I was on the fence about building a box, but after seeing this at the price point and exact dimensions it was a no brainer. This box is perfect and the quality is great. Would recommend to a friend.

Great for my RE 12" Sub

Nice box. Well built and very sturdy. I like the binding posts, too. I had to file the opening just a bit to fit the RE SEX V.2 that I put in it. No biggie. I also pulled back the poly-fill that was covering the vent opening and stapled it to the vent board so air could move more freely.

By EdP on September 8, 2016 Verified purchase

Great value

This kit is much nicer than most in its price range. Even though the wire is CCA, it looks to be full 8 gauge. The fuse holder and RCAs look to be of decent quality, and the separate remote wire and extra speaker wire are nice.

Amp Kit

The amplifier kit is real good quality….
But didn’t need it in the bundle. Good price for both though!!

By Donnie on September 14, 2022 Verified purchase

Insane difference!

I have a P2 Rockford and I have had it in the same box the stereo shop that sold me the sub included in the "great package deal". So the whole time I've had this setup I've wanted to get a new sub cuz it sounded like a "Rampage" brand from the local auto parts store.
A friend of mine recommended I get a more properly sized enclosure. So I ordered this box and when I got it installed and turned it up I couldn't believe my ears. It sounded amazing! Great quality and performance for the price I 100% recommend this product!

Great box

I bought this box for a 250 watt Rockford woofer. When I installed it to the box and tested it, sounds really good. Great size not to heavy.

By Anonymous on September 29, 2019 Verified purchase

Great Value

I bought this for my 12” Alpine. Sounds awesome. Cheapest price and quality is super.

Free Box

The box was free with the purchase of a 12 inch infiniti Kappa sub. I read a review stating that it perfectly, that is not true. I had to widen the hole so the sub could fit flush. Why include a box when its now made for it?

Anyways it seems to be durable and do not take up much space which was a plus for me being a family man. It do look cheap though. I can't speak on sound because the kappa is weak compared to my 15 P3 so I'm not sure if it's the box or the sub. I think it's a good box for an overall cheap set yup. I plan to go sealed

Major air leaks

I got this free with a sub (IDQ12)
The box seems sturdy and well constructed but the air leaks were so loud that I couldn't fully enjoy my new subs. Not sure if I can do anything to remedy it on my end as I don't wanna go thru the hassle of doing a return. I'm sure it's a great box. I just happened to get a defective one.

Cannot be beat for the price.

Heavy construction with heavy duty speaker terminals. Very pleasing to the eye with good quality carpet.

Single 12" Vented MDF Subwoofer Enclosure (Belva 1SV12B)

Box is correct size carpet was scared when I got sound is good overall price is ok

Amazing quality

This box is incredibly solid, my 12inch Alpine mounted no problem. The port on this box is nice and had a really good tone, excellent sound, sounds like a 15inch slamming I'm my trunk. Will fit in a 1994 Ford Mustang with no modifications if anyone needs to know.

Nice Box!

Well built and stands up to my digital design's 712 hits highs hard and picks up some lows overall great frequency output! Definitely worth the money and looks good with my car interior I'd highly suggest.

Nice box

Strong nice box. Put a Cerwin Vega hed 12 in it and it sounds amazing.

Hole too small for p3

I just received my sub box and the hole is 1/8 of an inch too small. I have a Rockford fosgate P3D4-12.

Solid!

Nice solid enclosure my infinity kappa hits very nice in this

Great value

Box is sturdy and nicely build. However the speaker wire attachment wasn't to good.

Great box for being a prefab!

If you are just getting into car audio and want something ported and have an entry level P2 or something along those lines, this subwoofer box is amazing for the 12" subs!! I upgrade my sub a week ago... Unfortunately it's choking my new sub like a mofo!! But it's also a custom built psi platform 2 with hd upgrade ????. Overall I'd recommend this to anyone who wants to start off car audio with ported boxes

Weak terminals

Terminals are weak. At 1 ohm 800 rms they melted. Other then that sub sounds good. Nice strong soild box

suprised

I wAs surprised when it came in the mail how heavy and greatly built and sturdy it was out my Memphis in it and was blown away 50 bucks sounds like a lie but your won't be disappointed

Decent box

More than a decent box for it's pricepoint.For subs in range of 150 to 500 watts, it's good.I can't build an enclosure this cheap.Like most prefab boxes,it lacks bracing(which I add myself from mdf scrap leftovers of previous builds)which shouldn't be needed if not pushing serious wattage.Great box for budget or beginning enthusiasts!

It bangs

What a great banging box I dropped a vcw122 and am pushing about 900 rms and it hurts to sit inside the car with some songs.

Wow! Made to last

By the description I figured this would be a decent box but when I actually got it I was blown away! This box is the best made box I have seen! I’m very very happy and will never buy another brand! I also have to say the shipping was unbelievably fast! I’m a happy customer, from the quality of the enclosure and low price to the extremely fast shipping, I have nothing but positive things to say about soniceletronix! Happy happy happy!!

ported enclosure

Well made and padded inside. Looks good and sounds good too.

I have a 12JlAudio W3. Recently went from 2-12w6 to the 1-12W3. This Box was worth every dollar! This W3 sounds amazing in this box! Plus I save 25% of my trunk space not have 2-12s. This box definitely exceeded my expectations for my W3. Great quality at a Great Price! Don’t hesitate on this box just buy it!

By roy coffey jr on August 4, 2024 Verified purchase

It's a cable. It works.

Cables all work and ties keep everything tidy. Plenty of extra length in a Mazda 3. My 5ch amp RMS power draw with volume all the way up should be under 360w (realistically under 250 when not trying to go deaf) so this should be more than sufficient.

Pros:
Cables all sufficiently long for my installation.
Everything included made the install quick and easy.
Only 8ga so the wires aren't super stiff allowing for easy routing.

Cons:
None so far.

Other:
Hopefully never need to test the fuse 60A rating.

Great value prefab enclosure!!

A while back I purchased the skar audio single 12" SDR bundle with the 800w RMS amp and loaded SDR 12 vented enclosure and it sounded great. The problem was the skar enclosure was too big for my older car. So I put the sub in a small sealed box and it sounded like garbage. Fast forward a few years and I purchased a new car that could fit a larger enclosure. So I purchased this Belva vented enclosure and I'm so happy I did. I immediately got my bass back. It's crazy how much a box with the right volume and port measurements along with being tuned to the right frequency helps. Sounds as good if not better than the Skar audio prefab box. And the best part is this box has just the right specs for the Rockford Fosgate P3D2-12, so when I decide to upgrade to a better subwoofer, I won't have to find or build a new enclosure. Overall, it does the job and does it well. Just check the user manual of your sub and make sure this enclosures specs are exactly or close to what the subwoofer manufacturer says will make your sub sound best.

Great Box!

I had ordered a different box and when it arrived I knew it would not fit. I returned it and got this one. This thing rocks with the Kicker CompVR 12. I have it wired to 1 ohm with the HiFonics 1950 amp I also bought from here. If you own a 5th gen Camaro this box is pretty much the largest you can go. Fit by 1/8 inch.
