GTMAT 80mil ULTRA – 5sqft Car Sound Deadening Mat Noise Insulation Dampener Sheets

Worked as a replacement for under the backseat of my car after replacing the fuel pump. You wouldn't think that a little sound mat would mat that much different in road noise, think again. Drove around without and then after application. Much quieter.

I used this in my pellet stove to cut down on noise I was getting from a blower with bad bearing. It actually helped quite a bit.

Advertised at 80 mil but came only 50 mil but works great

used it for the outer metal of the door worked great but not enough for four doors. buying another batch for the rear doors. i used the 50 mil for the inner part of the door just to sealed the wholes. my doors sounds like a luxury car's door now.,..heavy and agressive

Easy to apply. Old, all metal pick up cab will never sound the same.

Used this to eliminate rattles on my rear deck lid on a 2013 civic. Have an alpine type r with kappa one amp and had a bad rattle from the rear deck lid. This solved the problem.

It's worth it

Wow, I was expected some low quality stuff when I ordered these but wow they work great. Had a bit of vibration and stuck a piece on and bam no more vibration
