    • Great product at a great price
Very happy with this stuff. So far I have only used it on my two front door but the results are outstanding. Very easy to cut with a utility knife, sticks very well and folds around bends and corners of sheet metal much easier than I was expecting. I used two layers on the outside door and 3 layers behind the speakers with a foam pad on top to absorb back waves. Then i put it on the inner door and sealed off all of the holes including the massive hole that the manufacturer leave to service the window mechanism...hope i don't ever have to get back in there lol... I tapped on the outside of the door and then the other side that wasn't treated yet and the difference in resonance and vibration was substantial. I also gained a SIGNIFICANT amount of midbass from my Focal 165 k2 speakers. Also big difference in road noise. Still have plently left over to do the trunk when I get some more time. I'll be using NVX sound deadening in all installs I ever do from now on. Do not spend thousands on great speakers, amps, processing,.etc. without proper sound deadening and install. Excellent quality at a great value ... show more

    • Stop debating and buy it NOW !!!!!
Style: 12 sq. ft. Door Kit (Black)
I used this to sound dampen structures inside my Klipsch Forte speakers. Applied it judiciously to woofer support structures and to the rear of the plastic horns. Great result and easy to do

Helps with sound deadening a lot. Easy to work with and plenty sticky.

    • Expensive for what they are
Style: 12 sq. ft. Door Kit (Black)
I ordered these sheets specifically to cover my exposed tailgate of my Jeep jk to prevent rattling from my subs, when I got them I then realized they were folded twice and were all wrinkled up. I ended up working around the wrinkles by cutting them off. Doesn’t look great but looks ok. Ended up using the rest in the floorboards. For the price I would recommend using something different, if Kilmat would come in black I would’ve used it but it doesn’t. I used kilmat throughout the rest of my Jeep and seems to work good for a third of the price of this, their product also comes in smaller sheets and aren’t all scratched up and wrinkled which won’t matter if you’re putting it under carpet. I did reach out to nvs and they ended up sending me 10% back but still not worth the price difference to me. ... show more

    • Goes on easy, doesn't peel back around the edges later!
Style: 12 sq. ft. Door Kit (Black)
I've purchased and used the WEIZE cheapo stuff, the 120ml is okay, 80 and 50, no bueno. Once applied, had to go back and hit the edges and in some situations, tack it down and it still pulled up around the edges later, mine did anyway. I prep the surfaces and warm the sections in the sun or the oven prior to getting to where you want it, it still, seems to be inexpensive for a reason. This NVX, very surprised. Thick, pliable, easy to cut, applied the same way, and no issues. Just did an entire car interior with it, definitely recommend it! ... show more

    • Best value!
Style: 40 sq. ft. Bulk Kit (Silver)
Review Image by James Musselwhite James Musselwhite
I am a professional car audio installer and have worked with almost every brand of sound deadening. This is slightly thinner than Dynamat and about the same as Stinger roadkill extreme. However even dealer cost of both of those other brands is more than $50 more than this kit! This stuff lays down VERY well. Minimal bunching, great adhesion. I just wiped the floor down with alcohol and a tack cloth as I was doing some body work and it was quite dusty. Overall you can’t beat the value! One pack was more than enough to do the floor of this 98 c1500 extended cab! ... show more

    • fantastic product!
Style: 40 sq. ft. Bulk Kit (Black)
as stated this is a fantastic product and the price is unbeatable! It is very dense for the thickness, conforms very easily (I recommend using a heat gun as you roll it for ease of install), very sticky and most of all it works! Installed in my 92 K1500 which was a complete rattle trap to say the least... The stereo would have everything in the truck flexing and rattling so bad I didnt even want to listen to it anymore... I applied to main problem areas (roof, inner door skins, rear wall of cab) and wow what a difference! Sounds so solid and very little exterior/road noise (and I have 3" exhaust and super 10 mufflers)... Will soon be re-installing the stereo equipment so I will update my review to let it be known the improvement there ... show more

    • Not on par with other materials
Style: Black
I like NVX products but this one was just not enough. I installed in a Jeep Wrangler to reduce panel noise and help the OEM sub on the floor. As for road noise reduction...minimal is a kind word for this. Roadkill and some other company make a better road noise product with larger coverage at the same price. The foam on this does help a bit with panel vibrations. It is lighter than the other two main products used for this purpose I think it's best suited to reducing air space, not quenching vibrations. Anyway, I used it inside interior trim pieces, the deck, and the body sub enclosure. I got the best bang for the buck around the plastic OEM sub enclosure; no buzz, no vibrations, and increased the contact between the sub box and the body panels making it stiffer. Some improvement on the inside of trim pieces and next to nothing on straight body panel pieces for road noise. Also doesn't seem to stick as well as RK. I'll run it for a month or so and if I have to take it out, RK again because it always delivers. ... show more
