Default C6 Bose amp replacement harness

Hello,
Has is there a source for a plug and play wiring harness to replace the stock bose amp on the c6? it seems that all the speaker outlets, save for the subwoofer on the door that have integral amps (signal is derived from the main speaker signal in the amp), can be fed from a new amp that either receives high level signal from the speaker terminals from the head unit or RCA outputs from it.
TIA

I’ve been looking for the same answer and after much reading people are just running new wires to the speakers from the new amps. Someone even recommended buying an old Bose amp, removing the plugs and soldering cables just so it plugs into the original harness for you to access the speakers. I am on the same ship as you. Keep me updated if anything comes up.

I just finished after market amp and speaker install in my C6. I tapped into the factory speaker output wires coming off of the factory non Bose amp. From those taps I ran my 9wire from there to my amp behind the passenger seat. I use the output wires for the mid rear and door subwoofer. It was a lot easier than running new speaker wires
