Does anyone have the wiring diagram for the Grand Prix GTP with the bose system. I have replaced the head unit and are re-wiring the rear deck. There is an amp in the rear deck ( bose amp I assume ) that I think has speaker lvl inputs ( as all the speakers still work after the replacment of the head unit so it can't be pre-amp lvl inputs ).

I would prefer that the head unit drive the rear deck ( as there is some type of fixed crossover in the existing bose amp that can't be changed ) but don't know which wires to splice to get the speakers directly wired to the head unit.

The rear deck has both 4" and 6x9" speakers.

Any help is greatly appreciated.

Thanks

My Grand Prix GTP is a 2002 with on-star.

Also, I had a question about the tweeters on the front doors. Is there a crossover in the door or is it on the speaker itself.

Thanks again for the help.
