My ZX2 has the 6-CD changer and a tape deck - pretty standard. My front right speaker works, but that is it. I have swapped out my radio (twice) and my amp and even tested the speakers that don't work and nothing. I traced the wire(s) from the back speakers all the way through the carpet (took it out when I swapped grey for black, looked under the dash, and checked the connectors in the back of the radio - nothing... I didn't see any cut / spliced / missing wires, and noticed that the right front speaker has wires going to the right of the dash, while the left front speaker, and the two rears all run to the left side. Any help would be greatly appreciated!!!
