NVX!

The following review is for SDTK20, which is a part of the bundle you are viewing.

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

Wow good stuff

The following review is for SDTK20, which is a part of the bundle you are viewing.

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.

NVX Trunk Kit Sound Dampening Mats

The following review is for SDTK20, which is a part of the bundle you are viewing.

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 Sound Dampening

The following review is for SDTK20, which is a part of the bundle you are viewing.

Bought this kit to help stop some very annoying rattling. It did the job! Helped alot with road noise too! Definitely made my system sound alot better. The whole kit covered my back deck, trunk lid, and front two doors. I'd definitely recommend this. I'm going to be ordering more in the summer to finish the rest of the car. It might be expensive but it was well worth it.

Three suggestions however.
1. Use gloves, other wise you have to use goo-gone to wash your hands. (Or panels you get this on). The paper scratches you up a bit too.
2. Make sure you clean the dirt off the panels, otherwise you'll waste this. It won't stick to dirty/dust.
3. Get the $9 roller, makes the job much less of a pain.

The NVX SDTK20 kit is just what I needed for my trunk, and to my surprise there were a lot of sound dampener for the buck. Installation was a breeze, if you need to sonicelectronix has a video showing how to install.

Handy stuff for the hard of hearing....

The following review is for SDTK20, which is a part of the bundle you are viewing.

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.

The following review is for SDTK20, which is a part of the bundle you are viewing.

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.
