Review on Optimized Speaker Amplifier for GM Genuine Parts 20918769's Radio by Jose Gerber

Revainrating 5 out of 5

Excellent product, the best of multi-channel amplifiers

Works great. I was easy to install and saved hundreds of dollars installing it myself. I have a 2012 cadillac srx and after installing it it worked like clockwork.

Pros
  • Handy item
Cons
  • Some difficulties
