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

Excellent

Works well and good service

A bit smelly but they work a whole lot better than the Amazon version which is currently wanting to fall off. I definitely recommend these and make sure to buy more than you need because I always make that mistake.. I use these for more than just sound deadening. Thickness is fine in my opinion and it does what it should by keeping sound at a minimum. Very easy to cut and sticks very well.

Soundproofing for my 2025 RAV4 worked as described. The box did not contain enough material to soundproof the space for the spare tire.

Use this on my 2026 Tesla model Y juniper for sound deadening inside the doors when I had them apart to install self presenting door handles and soft close door latches. There is essentially no sound deadening in the door other than a pathetic little piece of sticky foam right in the middle of the large expanse of sheet metal on the inner door as it comes from the factory. Despite them upgrading the new model Y with acoustic glass, I feel that internal door sound deadening such as this, is mandatory to prevent "tin canning". It seems to subjectively make a huge difference as my wife states that it is probably 80% less noisy in the car since I did this to all four doors. Highly recommend this as it is both effective and economical.

Affordable and worked perfectly.
