GOSCHE 394 mil 16 sqft Sound Deadener for Car, 10mm Thick Sound Deadening Mat Materials Can be Better with Audio Noise Insulation and Vibration Dampening 9.8″x 15.7″(15-Piece)

This product does excellent. I put it in my F150 and my subwoofers don't rattle at all. All you hear is fantastic music. It is also a huge money saving item. There was enough to cover the back of my cab and then more. I am going to put it the doors of my truck as well. There is no odor at all, it seals well against any surface. I also used it to protect my RCA cables from interference. Great product.

The 15 of 394 mil was enough to surround both wheel wells in my van, and I had 2 full pieces left over that I used elsewhere. I used 2" aluminum foil tape to seal all cuts/joins. I found the adhesive to be adequate but not excessive. It works best on bare or painted metal, but also adheres to wood. It is flexible enough to adhere to rounded edges, if the curve is significant you may need to cut out a small triangle so it sits flat.The silver material is of good quality and doesn't easily tear.I haven't driven the vehicle yet to know how well it does to reduce road or suspension noise.

Worked great on my rzr pro xp. I used it to stop the heat from the turbo and fix some spots in the tunnel that heat comes into your cab. Lots of square here and they stick like crazy.

Work as it should. Used it on my boats. Is no more rattling from the Bass. Would buy again.

Seems to be a pretty good sound deadener for the money. Purchased it to cut the noise from my 1967 Dodge’s roof. Wanted something that wasn’t as heavy as Boom Mat to adhere to the interior roof. Moderately dense, foam-based material. Much thicker than butyl sound deadener (this is close to 1/2” thick). Easy to work with and conform. Had best results cutting with large, sharp scissors and using upholstery adhesive on the roof before peeling and sticking this on.Happy with it for the roof but would I personally not use for the floor. Too thick and spongy for me. Will not cut the sound as much as a butyl material but still cut exterior noise noticeably.

Easy to work withWill stick to anything

Not very moisture resistant.

Works pretty well, extremely strong adhesive backing, never worry about it falling off.
