Metra 70-2054 Amp Bypass Harness reviews
I recently bought a 2003 Silverado with Bose. The OEM stereo seemed to function correctly, but there was no sound. After a little searching, I concluded the factory amp most likely died. So, I came to Crutchfield to put together a package for me to replace the factory stereo with a double DIN and harnesses to bypass the amp. Everything works great. The LC-GMRC-01 hooks directly into the factory truck harness and supplies the new stereo with power. It also returned the safety chimes that were lost with the death of the factory amp. In addition to the LC-GMRC-01, I used the Metra 70-2054 Amp Bypass Harness to hook up all the speakers.There are two harnesses that connect at the amp. You unhook those from the amp, connect those two harnesses to the bypass harness, run those wires to the new stereo and connect the wires according to your stereo instructions and the instructions for the bypass harness. I'm writing all of this out because I never really found clear answers for my situation online. And, apparently the GM Bose systems are known for this particular issue. Maybe this will help the next person.

Pros: It works Plenty long
Cons: Maybe too long for most applications Wire colors seem very unconventional when matching up to other parts
