amp wiring?

[scuba]

the guy that owned my car before me was a complete *****! ive spent two weeks just trying to figure out what he has done with the wiring - anyway he has cut all the amp wires out of the speaker system - but it still retains the factory harness and amp( for the amp wiring anyway, everything else is cut to pieces) can i splice this back into my system - im now using a blaupunkt deck. anyone know what wires are what?
