Customer Ratings & Reviews

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 sound

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

sounds great

Box sounds great. Only problem is the trim ring on the Hifonics subs wouldn't fit without a little grinding.

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

Great price

Speaker box is very nice the only problem I had was the face plate was to small for my speakers I had to cut a bigger hole so they can fit.So watch out for the size,dimension on this product. I would recommend this product

Solid Box

this box is pretty solid. i have had it for around 2 months now and its workikng great with my two alpine type s. it feels well bilt and looks nice with the shiny front part.

yes

This box is nice and heavy. It looks sexy and my nvx 12s fit in it. I would recomend this box. I dont like the terminals but thats not a big deal.

Bargain Package Deal

Looks & Sounds Great...Box is put together well & Speakers sound Amazing

awsome value an great look

I just got one Belva BB212BK BOX ,pretty big for two 12" NVX the sound was smooth and had just the right amount of bass

Great looks with great construction.

It's simple and straightforward. The construction is great, and it came securely in another box. Separate ports for each sub. The is the best you're going to get without paying an arm and a leg for a custom enclosure.

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.

Ok..

Not even a couple days after bumping two gto jbl in it the carpet started to split... But overall I like the bezel- but only because I paid close attention to diameters and measurements of subs I bought compared to this box's measurements. Would be better if they made it to where you could wire in a series the correct way.

Good wire

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

Awesome roller!

I'm really happy that I bought this roller. I also have two other (smooth) rollers, but this one works much better. Its little "fingers" press the NVX sound mat really well and it allows it to be spread evenly over the entire surface including all these different curves and corners. The roller is very sturdy too. After 30 sq. ft. the roller started squeaking a little, but it still keeps working perfectly! I'm sure that the roller will help me to put all 60 sq ft of the sound mat and still will be fine. Great roller!! This item is highly recommended and even "a-tool-you-must-have!" for anyone who works with sound isolation of vehicles!

Way better than version 1.

I am an installer and could not disagree more with the other review. I actually had version 1 and got it the first time I ordered a bulk pack with Sonic years ago. This version is a big improvement due to the teeth and the handle. The teeth make it way easier to get a great stick to the vehicle body. The older one was wooden handle and this one is plastic, but the plastic is rugged and it is singular piece so it is really sturdy. The older one that connected the handle to the roller part broke at the joint and this one reminds me of a sturdy broom I have from Home Depot. Worth every penny paid or free!

Excellent value

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

All plastic

This tool should be free with purchase. All plastic. It does feel strong and it does work but not worth the money.

Another GREAT PRODUCT!!

I usually build my boxes but with winter coming I don't have time. So I purchase this one and it is awesome.

Perfect for tight spots

I used this to install true 50 mil sound deadening in the doors and along the floor of my f150. I installed it with this and the more traditional roller. This is perfect for inside the doors where bracing and cutouts don’t allow you to get great pressure on the material, the textured nubs give you much more focused pressure and allow you to get to stick and leave a small bit for air to escape when using a heat gun and following back up with the smooth rubber roller.

It also takes down kind of like a disposable razor giving you better access in some cases.

I used a cheap sound deadener from an online retailers house brand, the butyl rubber was not very tack and this got it to stay no problems I forgot to follow with the heat gun inside the door skins and this still kept everything secure.

Great handy product easy does it .

Great product , easy and handy to use , the roller is well crafted and helps out a lot . Well recommend happy with my purchase . The only concern I had was that I ordered it during the week before checkout it said I would be receiving my purchase on sat it took more than a week to receive it . Other than the shipping miscue I will purchase from sonic electronix .

Nice box

Nice box but once I put the speakers in it the front fence of the speaker box wouldn’t fit over the speakers the holes were to small so I had to pay to get the face trimmed

$50 off the sub plus they included a box

Been wanting this sub but couldn't justify spending $200 when I spent $48 for my Infinity which is pretty good. But the Polk was on sale and came with a ported box which was nice. Not a great box but gets the job done. I'll be doing my own custom box. Overall it's great value. I have it wired at 2ohm and this thing rocks! Everything I play sounds great. Paired which my Polk front and rear speakers and 5 channel amp it all kicks ass

Bang for Buck

Its pretty good sound deadener and it includes enough to do your doors. My door went from sounding hollow to solid. It definitely made a difference in the sound quality.

By kumar on December 14, 2022 Verified purchase

Wonderful

I used this in my doors and trunk. I tried other sound deadening products from Amazon that were trash compared to NVX. Easy to cut, easy to place, stays in place, and is thicker than the competition.

By Roger on January 25, 2021 Verified purchase

Pliable and sticky even in cooler condittions

I like it! it was in the closet and I took it to the garage it was 45º this stuff still conformed to the curves and stuck like crazy even in the cold!
Love the color I was using another brand (silver) and where the seat doesn't cover its highly visible black makes it blend in with my black truck.
looks nice and deadens like it should!

By TOYZ on January 13, 2021 Verified purchase

Works ok but handle is tiny must be made for tiny people. Plan on strapping on a bugger handle.

Polk Audio MM1 12Inch DVC

This sub is freakin amazing! Polk Audio is the best. Paired with the new MM1 6.5 components. Sound is TRUE. I could never buy any other brand for speakers. These things sound like you're in a recording studio. Crisp and Clean.

Good value.better than name brands.

I bought this after using the chrome version of this. I liked that it was black and had a “better look” than the chrome one. Even do it says it’s the same thickness as the chrome one it feels thinner but the same thickness as the stinger roadkill. I did find that it was easier to work with than the other nvx version and stinger. It is still a good value and has hold up since 2017 in the Northern California weather. If I had too choose between the nvx chrome one and this black version I would go for this one if looks was a concern other wise the chrome version is a better value.

By Joe on April 24, 2016 Verified purchase

Must have

It’s a must have if sound deadening your vehicle I have the smooth nvx roller and this one as well they both have there place in the sound deadening installation process I recommend you get both you won’t regret it

GREAT BOX

Great box. It arrived almost an entire week early to my APO box (pretty impressed) and in perfect condition. My Sundown Audio SA 12's fit perfectly in the cutouts. This box slams with the SA's running at 1500w RMS. No port noise and plenty of punch in the lower frequencies. I would definitely recommend this box to anyone running a medium sized setup like mine. I did have a little issue getting it in the trunk of my E39 BMW but nothing to complain about.

Excellent product!!!

I would definitely recommend this box. Excellent quality, shipped on time, and sounds GREAT!!! You won't find a better box in this price range

This box slams!!!

This is a awesome box well built and very solid worth every penny!!
I put two Sundown Audio subs in it and it slams!!!
I honestly love it so much I am fixxen to order a second one so I can run four 12's in my truck!!
If you don't like rock solid low end bass that makes your car pulsate ,
or bass that hit's so hard it blurs your vision!!
This beautifully well crafted box is not for you!!
I highly recommend this product and Sonic Electronix I guarantee that you will not be disappointed with either!!!

By Rick Abrams on August 3, 2017 Verified purchase

This box slams!!!

This box is amazing for the low price! if you are looking for a heavy well built box that will shake the rear view mirror slam off your windshield look no further!!
I loaded this beautifully crafted sumbitch with two sundown audio 12's and hit it with 800 watts rms and was blown the hell away!!
I would highly recommend this box to anyone who is looking to shake the pantie's off ya girlfriend or melt down grandpa's hearing aid from 2 block's away!
I will be doing business from hear on out with the fine folk's @ Sonic Electronix !!!!

Awesome Box!

I bought this peticular box as it was almost spot on for cubic feet for my JL Audio Subs. This thing is built like a tank. The carpet is good quality and the front glossy part shines real nice. If your looking for an inexpensive yet not cheaply built box, this is the one.

12" SUB BOX

Great quality build! Dual 12" Sub box with individual ports for each sub. Great sound quality!

By Al on February 19, 2020 Verified purchase

Solid construction and looks great

On initial glance look like a good box. Once I dug deeper I could see the construction was very solid. It definitely has some good weight to it. The speaker rings fit the subs perfectly. Great value for the price. I can't find any complaint.

By LocoSiete on March 11, 2020 Verified purchase

Nice box

Well made box, subs fit great and glossy insert is a nice touch

Almost perfect

Bout this box to house two of the new Alpine Type R 12’s. The cut outs on face plate of the box is a little too small for the subs to fit (if you keep the rubber ring surround on the subs). So mounting was difficult. After fighting with it for a while they worked out. Sounds great.

Best Box for the Price

This box is such an amazing value. It looks amazing and is constructed very well. The only complaint is that I had to resize the cut out for my subwoofers to fit. But overall it is an amazing value and I would definitelt recommend to a friend.

Great box

Great box in my opinion. I have 2 Orion XTR 12s in it and they sound amazing. Ordering another of these boxes to run 4 12s soon

Solid box

Solid box and it's well built however Rockford Fosgate p1 p2 or p3 subwoofers will not fit the trim around the hole is too small. I had to take off the glossy black faceplate to install the Rockford and it sounds amazing only getting A 4 star do to the faceplate I'm planning on trimming the hole bigger on the faceplate later on.

By joel on April 14, 2020 Verified purchase

Caution!

Most subs with beauty ring or thick mounting ring will NOT fit in box. Will have to cut subs or box.

By Jesse on August 15, 2024 Verified purchase

Perfect addition to tool box.

This little tool helps install sound deadener easier than the flat roller. I still use both depending on the application.
