Need wiring help for 2005 Grand Prix.
I'm hooking up an amp in my 05 Grand Prix with the factory stereo (not Bose) and I'm using a line out converter hooking it to the rear speakers so I can run my RCA cables, but I'm not sure which wires are + and -. Also, where is the best place to hook the remote turn on lead for the amp? Do I have to pull the deck out, or is there a place under the hood that I can hook onto? I'd prefer not to pull the deck if at all possible since I have to run the power cable to the trunk anyway, I'd rather just run it with that.
Thanks for any input!!!!
