I am looking for a wiring harness that will let me use my factory stereo as the source, and add an amplifer, and use that amp to feed my door speakers. Is there a wiring harness out that will take the factory stereo output and turn it into rca with a remote turn on lead? I dont want to cut up my factory wiring just yet.

 

Some amps have a LINE in source If not get one of these...

You'll put it behind stock radio then run your rcas to amp. I posted a 4 channel so you'll only need one.
