I dont remember which ones I tapped into on my head unit (stock Bose), I know it was the rear speakers, and I tapped in the line out convertor at the head unit so that if I ever did replace the head unit, my RCA cables were already ran to the front of the car. Mine has been working for over 5 years with no problems. I will be taking out the head unit next week to replace the display bulb, so I can tell you what color wires and where its connected then if need be. Mine is also an 01 GTP so there should be no difference.
