No, leave the amp alone, just run your own wires, just trying to look at the amp is a pain. The factory radio has only left and right outputs. Front and rear fader is controlled by a dial by your hazard switch that adjusts the amps front and rear volume. If you manage to use the factory harness it will sound like crap. Plus the factory amp won't power anything larger than 2 6X9 with out crackling. Been there done that.... The antenna has it's own power supply, like an aftermarket amp it only needs a signal 12V input to function..
Just use a blade connector and hook into the factory power. I'm doing the write up and will be finished with it by sunday afternoon, be patient, or your are going cause more problems than you really want. Short out your factory amp and you'll keep blowing #27 fuse and and your central locking system lights and OBC will be out too.
Don't forget: Assumption is the mother of all f*&K ups....
