Welp... I bought me a Kenwood deck yesterday because my stock radio died and I need music... SO this morning I took out the stock radio and started connecting wires for the new one, with some help of a few charts that say which wire is which... SO... I have power to the deck, but the speakers are inoperable... I've tried just about every configuration I can think of for every speaker and NO sound is coming out... Any ideas on that??
