Greetings again all. So I am at the stage where I have installed the 2 new fronts and the 2 rears in my 1998 Grand Prix without amping them. I spliced the tweeters onto the fronts so they stay functional and I removed the second speaker set from the rear to open up 2 small holes in to the trunk for when I install the subwoofer. I have a question at this point.

Which wiring harness/harnesses do I need in order to add the 4 channel amp for the speakers and another amp for the sub while keeping my OEM stereo? I would also like to keep my radio and steering wheel controls functional.

Thank you.

if i understand what you are asking...

That's the harness I would need if I were installing an aftermarket head unit. I would like to add a 4 channel amp and a 1 or 2 channel amp to the STOCK head unit while keeping my steering wheel controls functional. Thank you.
