NEED HELP Installing Car Deck

[BMW03]

I am having trouble installing an aftermarket CD Deck. I have tried several things and all I get is power to the deck and no sound out the speakers. I tested that my first deck was fried from previous years, but then the second deck was fine it just wasn't getting sound to the speakers. I know it has something to do with all the wiring. Because all that comes to the old deck is two wires that say right and left. No positive and negative. Someone help I don't know how to wire it.



Thanks :crazy:
