Car Sound Deadening Material Mat - 197 mil 8.7 sqft Auto Audio Deadener Foam,...

These pads work very well. They have excellent adhesive backing and stick to both smooth and rough surfaces. They were very easy to cut with large scissors and/or raiser blade and straight edge. Will order again when needed.

This is the perfect way to sound proof your vehicle and the perfect amount for a great price!

Super sticky easy to work with

It's actually a pretty good sound absorber and vibration absorber for its thickness It sticks well it peels well You might want to order two packs I found this stuff easier to use than anything else when it came to stuffing small areas in the car because if it's flexibility and ran out of it faster than I expected

Used this in a speaker box build and it definetly worked well, significant difference in vibration. Very much worth the money. Only downside I could see is with how sticky the material is, the foam likes to stay stuck to whatever it touches which in reality is a good thing. Tried cutting with a utility knife but maybe there’s a better tool that would have made it easier to cut
