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 SDTK20 dampening material, you will notice a higher quality sound from your system as well as a drastic reduction of road noise. With 20 square feet of material, you will have enough to cover all of those problem areas that have been bothering you for so long!

NVX Trunk Kit Sound Dampening Mats

August 4, 2014

I purchased the NVX Trunk Kit because it had the lowest price compared to Trunk Kits from Dynamat, Stinger & Ballistic. Since all the kits cover a 20 foot square area, I did not want to spend up to $80 more for basically the same product with a different name. It's Sound Dampening, how scientific is it? I've used Dynamat in the past and the only difference between Dynamat and NVX sound dampeners is the thickness. The NVX dampeners are a lot thicker, which makes them heavier. I don't necessarily want the added weight, but lining my trunk with the NVX Trunk Kit did make a noticeable (deeper sounding bass) difference in the way my 2 - 10" subs now sound as compared to before I lined the trunk. Installing the NVX Trunk Kit is the same as with all the others, again, it's Sound Dampening. I'm not talking about complex electronics here people. Those who disagree either work for Dynamat or Ballistic or have no clue.

NVX SDTK20 Trunk kit

April 12, 2014

This is really good sound deadener for the money. Very thick and heavy, extremely sticky and rolls on very easy. I had previously used spray on sound deadener and wasn't happy with the results and I was able to apply this right over top of it with no problem. Also I had more than enough to do my whole trunk floor and trunk lid. I still have some rattle but it made the bass sound way better. For the money you can't beat this deal!

Great product!

December 11, 2014

Thicker than the competitors, very nice to work with, and a highly durable product. I'm a finishing carpenter by trade and specialize in commercial finishing. I've worked with thousands of products and know quality when I see it. I received 2 18" x 32" sheets as part of their promotion on another component I ordered and was so impressed I ordered another 60 sq. ft. I have spent countless evenings researching sound deadening and am confident I chose material on par or better than anything else on the market.

This stuff really works when it comes to sound deadening really worth the money and you get enough to cover most of your trunk. If you have a large trunk you might need another sheet or two of this stuff. The only thing is about this stuff is don't touch the tar!! Omg that stuff is a pain in the butt to get off your hands or off anything else unless you have goo be gone. But other than that it works perfect.

August 23, 2014

I bought this for my 2003 Honda Civic and it helped A LOT. I've only used a little over half but I got most of the rattling spots in my trunk and have plenty left. The design of it is pretty cool, I like the aluminum look it has. I've had it for over a month and it's holding up really nice. It's taken some brutal heat (well over 100 degrees). I used a hair dryer just to make sure it would stick since there were some spots I couldn't use the roller. But this has definitely helped with the rattle and I noticed the bass seems a little louder too.

Best sound deadening I have ever used

April 6, 2014

I have used dynamat for several years now until I found this product. It is easy to install very thick and the price is great. I had to install two layers of dynamat to equal the thickness of the nvx. Thanks to sonic for the recommendation of this product.

I bought the 20sq ft pack to do the roof of my 99 Toyota extended cab. This stuff is very thick and sticky. Went on no problem and is doing a great job. I only used three sheets to cover my whole roof area so I have two sheets left over. Time to buy more and put some inside of my doors. I am sure it will rock.

Worried about product quality bcause of lowprice? Don't be.

February 14, 2014

With the need to budget in todayís economy I put fear of a bad quality product and possibly having to replace it behind me and ordered. I must say for a company I had no idea existed, the product turned out to be better than anything used in the past. It is easy to cut, easy to roll; and lives up to my expectations. Great product, donít let the low price fool you. I will be ordering more to outfit the whole car.

Product applies easily - installed in garage at about 50 degrees. Tried heating sections prior to application with portable heater, but it gets too sticky. it works better at cooler temperatures. No smell, cuts easily, and is far less expensive with the same specs as Dynamat.

NVX!

September 19, 2013

Excellent product. Thicker and cheaper than dynamat and boy does it work well. Got 100 square feet of this and treated my entire vehicle. Road noise is reduced. Temperature is more even in the Cabin. Doors sound way more solid when closed(Used 3 layers on the inner most part of the door and one layer on the outer part, under the door skin, to seal it up) car stereo sounds amazing now. Even at highway speeds. I really recommend this product for a vehicle that is overly loud or if you are a car audio enthusiasts. Worth the $$ but set aside pleanty of time. Took my brother and I over 60 man hours! Lol

Handy stuff for the hard of hearing....

September 18, 2013

I am no audiophile--I bought this for my Jeep Wrangler, which like all variants of the original Jeep is a noisy beast, what with little insulation, knobby off-road tires, and a thousand protrusions creating horrendous wind noise. It was a challenge to even use my noise-canceling trucker's headset on a cell call. So I applied it throughout the foot wells front and back, mostly single layer with some overlaps here and there. It definitely reduced the interior noise level--not as dramatically as I hoped but I sure wouldn't take it out! Installation was ridiculously easy--its tacky but not so tacky that you can't pull and relocate a piece. I was surprise by how wrinkled the aluminum was in places--and nothing I tried smoothed it out. But it is entirely functional and as it is under carpet plus heavy duty floor mats, appearance is scarcely an issue. Its been down for about 2,000 miles and so far, no signs of wear. Other Jeep folks--consider putting it in the back cargo area, too. I didn't at this point, but may well do so soon--cut the road noise a bit more.

Great sound deadener.

August 6, 2013

I bought some of this because it was on sale at the time to see what it was like and it didn't disappoint. I put this on top of the Stinger and Dynamat that I already have in my truck. It was easy to work with especially with a roller and heat gun for the hard spots. So now I've got 4 different brand sound deadeners in my truck, 3 layers almost everywhere. I highly recommend the NVX deadener over the Dynamat which is way overpriced. This is easy to work, forms well and doesn't tear your hands up.

20sq ft kit in a 07 crown vic

April 29, 2013

I installed this stuff in my crown vic, hoping to have enough to do most of the trunk. the trunk is so big i only had enough to do half. It definitely reduces rattles and vibration, its very easy to work with and install, and i didnt cut myself once. Im glad i bought the roller to go with it, it would be hard to do it any other way. I will be ordering another 40sq ft kit soon, to finish the trunk and do the doors. I love NVX audio!

Could this also be used for under the hood to reduce engine noise?
Tommy on Sep 14, 2014
Best Answer: Hello Tomas,

To even OUR surprise, we have had some fairly positive feedback from customers who have used NVX Sound Dampening under their hoods. Take this for what it is worth, of course; It is not very common, and even Less common for customers to get back to us. Typically No news is good news. We have an employee who has lined their engine Cover with this kit, and he has had no issues. A bit of context; it is in a Ford Focus, which will obviously have FAR less under-hood-temps than a Truck or V-6+ .

To be fair, we aren't Encouraging our customers to try it, because it is obviously NOT an 'intended use'. Attempt at your own discretion and risk.
