Solid Product, lots of it too
Ive had the insane rattling from my subwoofer and the highway drone from my aftermarket exhaust, and this 80mil sound deadening mat was the exact fix I needed. The 36 sqft kit (which comes as 33 pieces) was plenty to fully cover my trunk, rear deck, and floorboards. Since it's a butyl-based material, there’s no awful asphalt smell, and it adhered incredibly well with just a simple roller.
The difference is honestly night and day. My bass hits so much tighter and cleaner now without the whole back end vibrating like a tin can. Even better, the cabin is significantly quieter at high speeds; that aggressive exhaust drone is finally muffled to a deep, tolerable purr. If you want an affordable way to upgrade your audio quality and actually hear your music on long drives, I highly recommend this! It took some weekend elbow grease, but the payoff is incredible.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now.
The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it.
For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.

Worth it!
Size: 50 sqft
I was worried it wouldn't work as well since it's 50 mil and I thought I got the wrong thing. Nope! Works great. Did all four doors on my 93 civic and I have enough for the floor I think. Solid price. Noise reduced by about 5 decibels hive difference. Very sticky and easy to apply I'm so happy I was able to cover most all of my car. If I need more, definitely buying this since I got so much extra and I thought I would.
PS: that five decibel thing is only with the four doors. My firewall is next and then my floor, but it's such a huge difference

Quiet your vehicle noises
Size: 50 sqft
Put this in our high roof van and couldn’t believe how much quieter it was at once. Really cut down on the vibration noise Nice and easy to install just peel n stick. Was also easy to cut with scissors for smaller areas. Seemed to be really nice quality. Didn’t notice any odor.

Sound deadening the Hot Rod

Works well, good value for the money.
It’s very sticky and conforms to what you are applying it to. One 20 sq ft box did approximately the passenger side
