As expected

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

Great wire

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

Are You Kidding?

This box is just amazing, perfect in every way(for the price)there is NO possible way you can buy a better box at this price(including shipping)! end of story!!!!!

Awesome

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

Pretty good and Great Price

Bought this to go along with my Alpine type r and it works great with it.

awesome

im very pleased with the 12'' sub woofer box i order quickly without really doing research on it and im happy i did its perfect and nice fit in my trunk without taking up too much space

Good deal

Good box for a decent price! Just wish I had gotten the dual box instead if single

excellent

Would recomend for anybody. Sounds right and looks good. Made very good

Great box for my type r

Box sounds great with a type r. I have mine wired to 2 ohms on a hifonics Brutus brx 2000.1 with a second battery and zero gauge wire and it sounds amazing

BANGER!!!

Bought this box for a 12" type r that i had in a sealed box. It hits sooo much harder in this box that i will never get a sealed box again. This box has a wider range than my sealed had with much more punch. I have 1 12 running on about 700w rms in a 08 camry and its a lot louder than people in know with 2 12's. The flush sub mount also looks great compared to the cheaper boxes on this site.

pretty good happy with it

I like it. It works for me with this box my one jl hits harder than both ever did with the old box had to take off the trunk latch to make it fit in my 2012 . Mustang

Good value

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

ESSENCIAL NEEDS

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

Decent speaker wire.

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

very nice sub box

For a prefab box it is nice, I put a sundown 12 there 600watt woofer, the lows isn't to bad it could be better, but it wasn't built for the woofer specs. Construction is top notch and it looks really nice, I would recommend if your not a bass head, and putting into a nice car. And it fits in my 2013 mustang.

Great value

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

Thick legit wire!

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

NVX VSW122v2 (VSW122 v2)

This subwoofer is AWESOME! I'm even saying this after trying both the XQW and VCW 12". I love the XQW but it is too big to fit in my Underseat, 1.85 cu ft vented Dodge Ram Fox Acoustics box, so I went with the VCW. I like precision and SQ, and the VCW wasn't responsive enough. It is DEFINITELY an SPL subwoofer and can move massive amounts of air. I was hesitant to try this one since it's a lesser model than those two, but I am SUPER pleased with it's tight response for rock music and it's booming sound for rap and electronic. For it's price it is a contender with models in the $200 price range!
BUY THIS SUB NOW!!

NVX VSW122v2 (VSW122 v2)

A good woofer for the price. I purchased two of these wich are currently in a sealed enclosure powered by a 1200 watt monoblock wired to a final impedance
Of 2 ohms.. (Pushing 600 watts to each woofer). So far i have no regrets about my purchase.
Sure you can spend alot more on woofers but for my application for my daily driver these are great.

Booooom...

I'm running this off a NVX NDA102 amplifier @ 1ohm in sealed box. Sounds amazing and slams so hard I need to amplify my door speakers now. Great subwoofer for the price.

Worth the price for sure

Good quality item and definitely worth the price. Definitely recommend

Great price

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

Very good subs

Was kinda worried at first when trying to make up my mind on what subs to get but I went with these because of the amp I have couldn't have picked a better set of subs they r way better then I thought thanks nvx and sonic for sailing a really nice sub.

Perfect Box

This box was suggested to me as a match for my NVX VCW12 and it’s perfect for that sub in my opinion...well built and sturdy

belva 8ga BBSW127

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

Good quality cable

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

NVX VSW122v2 (VSW122 v2)

I’ve heard these subs before and they are good quality subs for an affordable price.

Awesome Sub

I bought 2 and put them in a custom box with a used kicker 750w amp. These subs absolutely slam. The range is good and the bass is clean I would recommend to anyone looking for some extra thump

wire

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

By Danny on September 30, 2022 Verified purchase

Beast subs

I would recommend these subs if you want some great sound but I’m going with the Vcws so I can really feel the bass. Update I sent them back and ordered them this and they get down. Basket came completely off magnet

Awesome sub box

Haven't hooked it up yet but quality and construction look excellent. Shipping was super fast. Delivered in 24 hours from the time I ordered. Thanks Sonic Electronix. Will definitely be coming back

By James on January 25, 2020 Verified purchase

Bought for home subs

So I bought two of these 12s for use in my home surround sound. Both are powered by a Crown xli1500 amp. For the money they fantastic. I highly recommend

Great quality little box!

This is surprisingly better quality than i expected. The size is not that big which is exactly what I was looking for and the carpeted part looks very nice and NOT cheap. The front glossy trim piece looks very nice as well. My JL W3V3 sub fit snug and perfectly in and it sounds deeper and cleaner than my older box for sure. The only thing that I actually was not expecting was that the box did not have wires attached to the terminals inside the box to attach to sub but good thing I had the ones from my old box and I just swapped it out.

By Robert on March 23, 2016 Verified purchase

Great Box!!!

This box is amazing for the price. It has a nice, sleek faceplate and an eye-catching design that I like. It's also filled with polyfill to cut out the port noise, which makes an awesome sound. The box is a little on the big side so with my Pontiac G5 i had to take out my folding rear seats to put it in my trunk. Even doing that, it was a tight fit getting it in, but once I got it in my trunk it was a perfect fit. It also has a flush mount for your subwoofer. It is a perfect box for my Power Acoustik 2500 MOFO 12inch subwoofer. I would buy again.

By Anthony on June 18, 2020 Verified purchase

Can't beat for the price

The box is well built true spec on MDF. A little smaller than expected but that's ok it's pretty heavy compared to other boxes around the same size. It does not come wired and you will have to find terminals through white polyfill to tear open a slit to run wires. Don't really like the terminals on the back but they work fine. Its a good looking box mine shipped fast and no tears or dents. as others said doesn't hit the really low lows that great but not enough to where id return it. I'm running an r series alpine and it hits HARD for what it is.

Belva ported box

Perfect size fit for my T2 12 sub sounds awesome would recommend solid box.

Great value, decent sound.

Bought this enclosure for a NVX VCW122, it sounds decent, plenty of bass, but crazy amounts of port noise. It would work well in a sedan or coupe, but in a hatchback or wagon, you can hear the port noise in the front of the vehicle. Overall, very clean box, very nice sounding.

By Buck on October 2, 2016 Verified purchase

Solid box!

It looks great and the materials used are of good quality. I have a 12" Kicker CompR in mine and sounds really good!. I would recommend. It is truly a great value for a great product.

Belva Box

Belva ported box works great paired with a Polk 12 and 1500 watt amp in my BMW, it's a bit larger than I expected but sounds great.

Great product

Great box Sturdy comes Insulated look stylish and look perfect for any 12 inch.. if you go with this you would be Satisfied with the box

Well made box

This box is perfect for the price. Durable, heavy, and it comes with filler. Makes my pioneer champion series pound hard. Some people thought i had 2 subs.

Bella BBX112BK

Very nice enclosure. Looks great. Very nice construction. I really like the recessed look where the speaker mounts.

Love it

Purchased this for my NVX VCW122v2 subwoofer. Finally gave up on finding the right sealed box and got this ported box which basically fits the subwoofer like a glove. Good construction, easy to set up, has spade ends for the interior connectors. The exterior connectors are banana or exposed cable. Belva sells a set of banana clips, clipped together by a red plastic clip, excellent, adds a little bit of a professional touch to the install. Get them, they're like $12 and worth every penny. What can I say, its the right box for the install. (Side note) The rubber ring that comes with the NVX subwoofer does not fit under the current piano black faceplate on the box, don't use it, its a headache.

BBX112BK

this enclosure came as a package with a Polk DXi1240DVC, it did really well in my wife's BMW for a little extra bump without stressing the stock speakers. would definitely recommend for the average commuter who wants a little more

Nothing much to say, it's a nice looking box. My Rockford Fosgate T1 sounds really good with deep bass..

Awsome sub

I have 2 vcw's 12's I am over watts in rms and have been for over a year they have held up very well and pound like hell.

awesome subs

I have a 10-inch dvc nvx and it is awesome! I use it in my suv. I decided my 12" Kenwood subs were just not enough. they were distorting at higher volumes indicating the subs couldn't handle the amp. so I installed these and opened them up. They were so loud it shook every bay door in my shop and knocked the snow off the roof I'd say I pushed around 600-700 watts! downside is.. I pushed my old xr900-5 amp too hard it is dead LOL Oh well! I have a jp95 5 channel down4sound amp shipping in.

By Peter on February 3, 2024 Verified purchase

amazing and cheap

i replaced the original speaker wire in my car with this and the difference is just crazy and this wire is really cheap so it’s definitely worth it. it’s a nice color and is very easy to work with.

Solid Value!

12 Ga speaker wire, with great insulation, for this price? I was skeptical at first but after hooking everything up I can say that this wire is fantastic, and much better value than Walmart/Amazon. 23ft for $7 of high quality wire? No brainer.

Solid speaker wire for the price

This is great speaker wire for the price. Has a nice protective jacket and very flexible. I usually stick to OFC wires but for lower wattage speakers and line output converters this is perfect!

Great Box Overall

I paired this box with the NVX DVC (Dual Voice Coil) 12 inch subwoofer. The box really brings out the bass that the sub is putting out. The box also feels quite sturdy and looks beautiful. I would highly recommend this box, especially if you'll be pairing it with the same subwoofer as mine.

By Adam on May 28, 2024 Verified purchase

Great box

This box is perfect for the NVX VS122 version 3 sub. Sounds and looks great also well built, quality carpeting and terminal posts.

By Dave on May 30, 2025 Verified purchase

Nice box

The only reason I can review this product is a friend has one and it sounds great. I had to return mine due to the size. Be sure to measure before you order. Does not fit 5th gen Camaro SS. Perfect if you have a SUV or a vehicle with a big trunk.

By Aaron on January 15, 2025 Verified purchase

Great sound and impact

I bought this sub to match up with my JBL Club A600 amp. Sounds very good in a large ported box. It hits the notes hard, and with impact. Its missing some of the low end 30-35 hz tones, but thats due to the box tuning at 42-43hz, not the subwoofer. A great value for the money. It weights between 15-16 pound. Highly recommend.

Great sub

The main feature I was looking for was the dual 2 ohm vc. 12's usually don't have that option and if it does they are expensive. This NVX sub drops to 20 hz and sounds great, wired to 1 ohm connected to a Rocford Fosgate 1200 D amp and this sub hits hard and deep.

By Dave on May 30, 2025 Verified purchase

What a great combo this is!!!

I installed the sub in the box @ 1 ohm, then connected the box to a Rockford Fosgate 1200 D amp. This sounds great, deep and mid lows. Couldn't beat this, with a lot of research this was the best deal and the sound is clean and clear.

By Dave on May 28, 2025 Verified purchase

Killer 12 inch Subwoofer!

This is a killer 12 inch Subwoofer for the price. We installed this 12 in my son's car and he loved it! It hit super deep in a ported box. I highly recommend this sub.
