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

Good stuff
Size: 50 sqft, Size: 50 sqft
Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.
