Lowered Road Noise...
Crutchfield Customer Review (What's this?)
Great product that does what it's supposed to do. It's easy to cut and install, though it tears easily if you're not careful, being so thin and all. Other than that, I like it and it made a difference in the back of my sports car.
Pros: Thin, light, easy to work with and install.
Cons: Because it's so thin, it can tear easily if you're not careful.
