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

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 box

I love this sub box. It looks & sounds amazing I am so happy I got it . If you want a box that looks and sounds really good you should get this box . U will love it as much as I love mine !!!!

Good box!

It handles my sub woofers pretty well! I'm surprised it is holding up so greatly! Highly recommend it to anyone!

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.

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.

Great box but it's to big

I would recommend this product, I like it alit except it's to big to fit in my trunk and had to put it in my back seat, so make sure you measure before you buy a box

All plastic

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

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 .

$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.

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.

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!

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.

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

Belva BBX212BL (BLUE)

Sounds good for a prefab box but if you want to get the best out of your speakers build a box to there spec's but for the cheap subwooffers I put in this box for a buget build I did for my sister this box is great.

By Anonymous on May 25, 2018 Verified purchase

best box ive owned

I would recommend this box I have two dual voice coil 12" subs in it and it sounds great,

Wow!!! Excellent box

I am now on box number 3 for my subs. This box has brought my love back to my system. Insane how much a box can change it and it looks amazing.

Look/Sound Good

Sturdy construction and is even insulated on the inside. It has good looks and connectors for the speaker wires also. I would purchase this brand again.

Great box with room for small improvements

I put a pair of Alpine Type R's in here and they sounds great! The box came in perfect condition, and on time. One of the first things I noticed was the wire terminal seemed to be pretty low quality, but are mounted very well. The pictures don't show this, but mine came with a logo screwed in on the corner of the blue/front part of the box. The only BIG con is that the port is very rough and sharp. Overall this is a good box and I do not regret putting this hefty chunk of goodness in my trunk.

By Gabriel on April 6, 2017 Verified purchase

Great vox

The box is made perfect and go's with my speakers. I would definitely recommend 100%

Awesome sound!

Went well beyond my expectations, great sound and very well built.

Belva BBX212BL (BLUE)

This box is amazing. Pros: It is a very nice box, has very nice terminals on the side of the box, and is very well built and very strong. Cons: It is pretty heavy but that is because it is so strong and well built, and because it has the white stuff lining the inside makes it hard to get the terminals out to wire them.

Great price great product

Nice big box looks nice and great price.Would definantly buy again

Very Unsatisfied

My 12” Memphis subs wouldn’t fit without taking the rubber from around it to sit in the box properly.
Very Ugly looking without the rubber around my speakers. Highly unsatisfied.

This a good box for the price

I love my box it go good with my blue car

All around great product

Takes a beating....as far as I can tell doesn't overheat or loose bass hit

By roy coffey jr on August 4, 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.
