Crutchfield Customer Review (What's this?)
worked great,instructions were good. Only problem I had was the rear speakers did not work,because the factory amp had to be bypassed. I found this out in crutchfields notes on my vehicle.
Pros: worked great,good instructions
Cons: Rear speakers did not work because of the factory amp, a heads up on this would have saved a lot of wasted time
