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.
