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.

I put this under my hood to make it less resonant and echoey. It made a huge difference. I found that the easiest way to install it when you need to be able to slide it around is by spraying Windex on the surface and on the sticky foam. You can then position it really easily, and when the Windex evaporates, the foam becomes sticky again and locks itself into position.

I decided to rip out the interior of our Ford F250 Super Duty to install sound deadening mat directly to the floor. I am bad at math and thought I could get by with one pack of the 9.8" x 15.7" pieces but should have gotten two packs. The adhesive is super strong and the material is very thick. This sound deadening mat was a great value and it has lots of uses. It's really effective at quieting road noise and I recommend it.

Great product, good price. Use this product around my car doors, and around my speakers. Easy to work with and sticks very well. Great for noise reduction, easy to cut, and help stop the vibration.

Works well, wouldn’t say it’s SILENT in the car, but definitely a noticeable difference in quieter drone noise from the exhaust

So far, I have noticed a little bit of a difference with just the little bit of sound deadener that I have applied. It is super easy to apply - just peal and stick. Make sure that you clean the area before you stick it down. Anyways, cheap step for a luxury feeling.

Works great.

Great product for a great peice. Very easy to put and stick to the bare metal of the vehicle to greatly reduce road/wind noise and add some insulation (especially in the hot region of the U.S.). Mock up, cut to size, peel and stick.

I've used these under the carpet and inside the doors of my 1993 miata and am pleased with the results

Sticks, for now, dampens the sound very well, hopefully it remains stuck. The adhesive paper and the over all quality is not the best.

Excellent insulation material. I used it for my house wall insulation, and it keeps me warm and cozy.

easy to install, simple to use, not as effective as I was hoping. when cutting foam (even with a fresh usility knife blade, the control interface doesn't cut cleanly the whole way. maybe scissors would be better
