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 SDDK12 dampening material, you will notice a higher quality sound from your system as well as a drastic reduction of road noise. With 12 square feet of material, you will have enough to cover all of those problem areas that have been bothering you for so long!

NVX SDDK12

June 11, 2014

Excellent sound deadener for the money, very thick, no smell once applied, super tacky and sticks even to dirty surfaces. Applied in my doors it made a big difference inside the car, applied in the trunk the bass sounds much better inside but it didn't stop my trunk from flexing and sounding like it's about to explode. All in all excellent product and would definitely recommend!

A lot of materual

January 19, 2014

Ordered this for my F Super Cab. I just wanted some material to apply to the inside of the door skins. It is a lot more material than I needed. Ford already has a small amount of sound dampening material. It did quiet the interior as expected. Great product. Came with no instructions. I just used some alcohol to clean the surface first.

Impressive product

January 6, 2014

This is a very stout, impressive product. It feels thicker than the famous competition and there is no smell to it. The sheets you get are sort of a long/narrow size, so they are great for running vertically up the doors and on the outer door skin. You'll definitely want a source of heat when working with these and really, there isn't a better value for the kind of product you are getting here.

Major Improvement

August 30, 2013

I ordered the pack so I could take care of a few flex and crackle issues I had on my roof, I applied the material in about 100 degree heat and it stuck and stayed easily. I used the nvx roller to adhere it and it worked nicely. The difference was night and day, it's tighter, cleaner and harder hitting. I did 2 layers above the subs and 2 layers above front seats in my ext cab pickup. Im running 2 15s on 3000rms so you know if it worked for me, it will work for you

Very Thick

July 3, 2013

This kit wont take your stock stereo and turn it in to a pavement shaker but it will help kill rattles and really helps clean up the sound. Its thick and very sticky so installation could be done by hand (I just used fist pressure) to work it on to the panels and make sure they are clean! Its somewhat easy to contour to corners and edges once cut in to smaller pieces and best of all, no smell! Overall, my road noise was still there (pretty sure you need to deaden your entire car for that be noticeable) but I did find my music with a lot of mid, such as metal, sounded MUCH better in my standard coax alpines.

Great for Rattles

April 21, 2013

Installed this stuff in my front doors and enough for the speaker area in the rear doors. It only slightly reduced the road noise in my car, but tightened up the bass and reduce rattles by a huge degree. This stuff is easy to install and can often be bought on sale.

Best way to improve your system's sound

November 18, 2012

I was desperate to obtain a warmer, natural sound in the Rav4 I had just bought and did not want to lose any storage room. I had better speakers and small woofers installed in the rear speaker compartments but was still left with a tinny sound. Advised by the installers of the improvement benefits of this sound dampener, I had it installed and then came back for more installation in the rear doors and rear floor (I had the front doors and front floor fitted initially). I am very pleased with the improvement and it is definitely worth the investment.

Good stuff easy to apply does the job

October 25, 2012

After an accident i decided to treat 2 doors with this product. The other 2 doors use the Raamatt product which is more expensive. Application and overall sound damping is very very close. Next vehicle I will likely do the entire job with NVX. It is amazing how far this stuff has come since the original tar no stick heat gun application stinky dynamat product back in the 1990's.

This was very easy to work with. It seems to be as good as any of the more well know and more expensive brands. Sound dampening at least the doors is necessary to seriously improve the quality of sound in your vehicle.
