Three wires going to two speakers is called common ground since they have to share one of the wires. Thus that wire is common to both speakers. Your HU will not like that situation. If that situation exist you have to run new speaker wires or one wire to make it "four" two to each speaker.

I understand the concept of common ground. However, what I do not understand is why the new HU will not like this. Is it because the new HU is wired for separate grounds for each speaker? If so, I get it. If not, please explain.

Also, since I have not started tearing into it yet I am unfamiliar with the location of the factory amp. Where is it?
