Well, I got the new hi-lo converter box and it turns out that it wasn't that after all. Mine was also the RCA jack on the end of the wire itself that was shorting. I can't say that I'm real pleased with that. The weather is finally making a turn for the good and I didn't want the bike to be down waiting for another amp, so I cut the wire so I could splice another RCA jack to the end from some audio jacks I had laying around. Let's just say that's no easy task with the size of that small wire in the middle of everything. I finally got it together and taped it up, but I have no idea if it will hold, since I didn't have any soldering equipment here. I've been trying to call Biketronics for the past few days, but they aren't sitting around waiting to jump on incoming calls. In their defense, I don't think they are some huge operation and I assume that their technical guy, Bill, is probably on other calls. I would like them to know about this. I figured that no matter what, to fix this was going to require either cutting the wire or replacing it the entire way back to the amp, so I couldn't do any more damage than how it came to me. I don't know if that amp opens up, since it's securely taped into place and I can't see the back side of it to see if there are any screws to open it up. In retrospect, if I was thinking straight at the time, I could have hooked up a "Y" connect audio cable to one amp to run both speakers for a temporary fix, and just sent the other back for a replacement. The end result is that now that both speakers are playing, it sounds pretty awesome.
