Suburban OEM Non-Bose Amplifier Location?

You do not need to turn the amp off. If you do the rear speakers will not work. I have been through this with a tahoe. Instead you need to figure out which wire on the factory harness is the amp wire and wire it to the new cd player harness. Then everything will work like normal.

Brian,

I was told to disconnect a pink wire, I did and it did nothing. I thought that this cut power to the factory amp.

My only problem with your suggestion is that my aftermarket cd player has a built in amp that I want to use to power the four door speakers, and therefore, it would be sending amplified music to the factory amp. It would have to be line level audio only for your scenario to work

Maybe the pink wire is the remote turn on for the amp, and if I attach it to the appropriate power connection that will fix it....? Except for the already amplified music coming from the deck. I may have to convert those to line level and run them through the factory amp.

let me get my volt meter out tomorrow and do some troubleshooting.

thank you for the info.

I fixed it! I connected the pink wire from the old harness to a remote power turn on from the new harness/deck. It works!

I still have no idea why it works...

Thanks for the help brian!
