Also.. would a faulty antenna be the cause of not getting volume?

If you are referring to the speaker wires only and not the power wires I would guess that the green wire is common ground for the speakers and the blue and gray would be the left and right channel signals but I don't know which would be left and which would be right. You could tell by using the left right fader if the radio has one. What is in the little box you are talking about. Also before you go crazy I would connect it to a set of speakers that are known to be good as they could be your problem.
