Stero AMP question

[Cunningr]

I already have googled searched form ect... and have not found information.

I finally decided to do the Double DIN radio mod the kit has all the parts for inside. What I am looking for is an adaptor for aftermarket amp into the factory wiring harness. Plenty of adaptors available for the head unit to factory wiring just can't find one for amp.

I have 996 six channel amp in now I swapped in from ebay to replace the 4 channel unit. Non Bose.

Plan:
Install rear speaker kit.
Install updated Head unit with NAV
Change door speakers to either shallow mount 6.5 subs or shallow mount 8"
Already updated dash speakers.
Last would like to get an updated amp. Saw a guy used factory amp bracket and stacked 2 aftermarket amps, just doesn't list an adaptor to the factory wiring.
