Excellent Product, Very surprising results
2007 Chevrolet Cobalt
Crutchfield Customer Review (What's this?)
I purchased this product since as a bulk package it was the best value per square foot. This covered all 4 Doors, the entire floor pan from rear seat to the firewall, the rear deck, and the entire trunk. This installation significantly reduced rattle and road noise as well as reduced the resonance of the bass coming from the trunk. I have 2- 12 inch Subs and they no longer shake the doors. While testing driving after installation, if there was no wind I would not have been able to tell I was driving. One of the downsides of my installation was the time commitment. I did the install by myself and spent about 30 hours over 3 days.
Pros: "Xtreme" -ly Effective Package went all the way
Cons: Time to install Glove highly suggested, I had many cuts on my hands and raw skin from the adhesive (from separating the mat from the backing.)
