Benefits of Sound Damping

Sound dampening material is key to reducing the rattles and shakes in your car. It effectively reduces the amount of road noise that is let in through the thin panels of your vehicle. It also lessens vibrations that are created by playing music through your speakers. It works by adding weight to the desired panel, which lowers the resonating frequency. You will notice by adding this material to your car, your sound system will likely get noticeably louder. If you have subwoofers, this is the perfect kit for your vehicle.

Thicker Than the Competition

NVX is one of the world's leading manufacturers of sound dampening material, and is up to 30% thicker than the other brands. Don't pay ridiculous amounts of money to kill those rattles, when you can get everything you need from NVX for a fraction of the price. With the SDSK2 dampening material, you will notice a higher quality sound from your system as well as a drastic reduction of road noise. With over 1-1/2 square feet of the material, you will have enough to cover the areas behind each door speaker.

Nice Wiring Kit

September 20, 2014

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

Quality stuff

September 17, 2013

This stuff is very easy to use, just make sure the surface area is clean first, preferably with a mild grease detergent like dish washing liquid. The sheets are definitely thick and can become quite sticky, so plan ahead properly. Best to do it on a hot day where the panels are already nice and hot. Can't say if it made a difference as I changed the entire stereo and deadened the car at the same time.

October 27, 2015

This is my first time using sound deadning and I can tell you that the installation was really easy and the diffrence was greatly noticeable in the sound level. I do not get any rattling what so ever. The product feels thick and of good quality. I would definitely recommend this to anyone trying to improve their quality of sound in their system. I can also hear the diffrence in road noise, it has been greatly reduced, if I had to judge, maybe about 75 to 90 % in noise reduction. This product is amazing!

I haven't used this type of material for a while so nothing else to really compare, but it seems to have worked well. 90mil makes this product one of the thicker ones on the market, and considering the price, I believe this is a very good product. It did calm the resonance of the doors quite well. It doesn't make the car quieter if it is used alone, but it does improve the sound quality of the speaker. It goes on to the metal and plastic surface pretty well. Hopefully it stays there for a long time.

Great for Removing Vibrations for Better Sound Quality

March 26, 2017

This sound dampening material really does the trick. It removed the vibration from my door speakers and made the sound more crisp and clear. The only downside is trying to apply it around speakers, has to be cut and molded properly for a good fit and better sound, a little tricky, but still doable.

I have NVX insulation around my front and rear speakers and I would definitely recommend it to a friend. The insulation is pretty thick so be prepared to make holes or cut as needed for proper contact to mounting surfaces. Its pretty solid and sticks really well, and as far as I can tell it helps with sound but I would have to cover the whole car to really compare it with other sound insulation products. I would buy this product again

May I put this in my box for subwoofer on walls ? Would make some difference in sound ?
Gelu P on Jan 14, 2015
Best Answer: typically you would want to put sound dampening on any peice of metal to keep the rattle from happening. Ive personally put sound dampening in a few enclosures i didnt hear much of a difference in sound or volume level. on the otherhand i have coated the insides of an enclosure with fiber glass and it make a bit of a difference

If I were install this on my doors for 6x8s...where do I put it? Just anywhere on on the metal framing?
Taylor M on Oct 16, 2015
Best Answer: You can use sound deadning to prevent rattling, keep the outside noice down and to stop the sound produced by the back of the speaker from going into the cabin. If all you care about is preventing rattling, then just put it anywhere you see that might cause rattling. If you want to keep the outside noice down, cover the the inside of the main part of the metal on the door (the inside of the part of the door that you see from outside). Lastly, if you want to stop the sound from the back of your speakers out, put the sound deadner over the openings on the frame to turn your door into an enclosure. Hope this helps.
