80 mil Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening 10 SqFt

This stuff works, put it different places on my Mazda Miata and it does a good job on deadening sound on the metal, put it into the trunk and under the seats and still have other places to put it down, don't need to cover all the metal to achieve the deadening and solid sound

Works great, easy to install (get a good roller kit)- great price for the quality

Fantastic product at a reasonable price compared to competition

Ease of installation

Isn't the thickest stuff out there but for a budget build this worked out fine, exactly the thickness of a credit card, see picture attached

Used this to cover areas in a subwoofer well. Made sure no rattles could happen. Applying and using was easy. Cut, places and used a roller. Sticks fine, no movement, and it was sticky enough. Sometime hard to get off the backing, but it comes off with no issues. Cut with a razor blade and it sliced fine. Not to thick so it doesn't take up much room. Works fine, no rattles after subwoofer installation.

I've used quite a few different brand of sound deadening and this has to be the best value that I've found so far. I recommend!

Easy to use perfect size sheets great value it really makes a difference
