So, I replace door amp in a speaker (which had been previously rebuilt, but apparently not very well as it lasted a few months). The new one was working great (thanks BrianK), then a few months later, my CD changer dies. I had gotten the jammed disc code before and fixed it, but this was the "see the dealer" code. So, I got a Alpine unit off Ebay and an adaptor cord. Plug it in and it works great....for two days. The changer seems to still work, but my head unit has completely died. The face just went blank and all sound stopped. The fuse in the driver side footwell is good. What's going to be next? I guess either way, I'm starting the hunt for a reasonably priced head unit.
