rear speaker is out, what color of wire is it?

[djactionman]

I have a mess from whoever did the install on this thing, I mean a real mess. I had some speakers just stop and have been fixing them one at a time, and now the driver's side rear speaker isn't working, and I think it is a wire in the back of the head unit. What color is that wire going into the unit?
