This is great material and is very easy to put on with a heat gun!

I found the price great for the product I got. Installation was very easy, product sticks very well (Remember to clean/prep the surface). I noticed a difference right away in my music as well as overall noise level while driving on the highway (Doors done - trunk is next). Not the thickest sound dampening out there but it def. helps :)

I recieved this as part of a package deal. It is enough to cover the lid of my 98 Civic sedan trunk. This will clean up the sound of your lows by decreasing noise (rattles, distortion of sound, etc). This is the first step in noise reduction and everybody should start here.

I doubt it will create a noticable increase in sound from your speakers.

Very flexible, sticks like crazy! Easy to work with.

Got the sound dampening door kit with some speakers, the installer put it on the rear deck of my vehicle where my two rear speakers and factory sub are. The difference is night and day, expensive but quality, good to get with speakers or a sub.
