2007 Chevrolet Cobalt
Crutchfield Customer Review (What's this?)
I installed the product without using the plate frame - I installed the dynamat directly to the place and screwed the plate back on! This surprisingly reduce rattle from the inside of the car, which means less rattle for everyone else!
Pros: Perfect fit "Xtreme" -ly effective
Cons: Didn't use the plate frame - Didn't like the idea of advertising what's inside to people I don't know.
