question about installing aftermarket stereo

I like to start off by saying i did check the manifesto, but alot of the images are no longer available or doesnt directly answer my question. im trying to do the factory amp bypass, i was hoping some one had the wiring diagram for the 2000 z3 roadster 2.3. basicly im going to remove the amp then take the amp wiring inputs and splice them to the amp wiring outputs to the speakers. im not worried about the subwoofer i have a aftermarket amp for that. any help would be great. also just so you know this isnt my first rodeo.
