not sure exactly which wire is which, hence the confusion, lol. i can get the colors of them tomorrow.
The yellow wires are all just plain yellow with no markings, but are of a larger gauge than the stock speaker wire, prolly 12 or 10.

hmm, never thought of using a battery to test for speakers, ill try that. so i guess all i really need to find is the power wire and ground wire. i just got a bit overwhelmed as there were alot of wires and decided to just leave it until i could figure it out
