Ok... I have had a long day so I confuse easily!
So you bought an AMP by-pass, right? If not, your head unit will likely blow th factory amp if it has pre-out.
If you pull both plugs off the harness, the one with more wires goes to the speakers. although I think its just one more wire? I did my opposite to find out I wired from an Alpine amp back to head unit instead of to the speakers....
