You don't need to bypass the amp, re-wire any speakers, etc. Just match up the colors on the harness to your headunit, make sure to connect the pink wire to the blue amp turn on wire, and you should be set..
I have to agree on this. I wired mine just like the diagram showed (new speaker OUTS to OEM amp IN), and it really sounds great. A huge improvment!
