Dynamat Extreme Bulk Pack is rated 4.1 out of 5 by 7.
Rated 4 out of 5 by from Deadens the noise! The product is easy to apply and works great. The only issue was the coverage. In cacluating the coverage you have to allow for the valleys and contours of the vehicle (About %20) more than the square footage

Rated 5 out of 5 by from Dynamat Extreme Bulk Pack I put this stuff on the doors of both my Toyota T-100 and my 1979 El Camino and gained so much more in sound quality from my speakers. I also got this for the roof of the 'camino, now when it rains I hear more music and less weather. I love this stuff. The floors of both cars are next!

Rated 4 out of 5 by from Dynamat very eazy to intsall I used Dynamat on the floor board and fire wall of a Alfa Romeo Spider I am restoring. It was very easy to install but did take some time. It cut easy with scissors and stretchs to conform to contours. Before I intsalled Dynamat the car was very noisy and the floor over the exhaust was to hot to put your hand on. After it was installed the Alfa was much queiter and the floor board was just warm. The shop that is making the carpets realy liked the way the Dynamat looked
