I was looking for a wiring diagram for my 04 Inttrepid SE so I could transplant my 12" sub and amp from my 88 S-10, and I found this place. I think I'll stick around and see what else I can find here for my car.
I have the Haynes manual for the 2nd gen Intrepid. I think there are some schematics in the back- I'll look. Also, you could search in the Car Audio and Video section for similar posts
What you describe sounds do-able
