In my shop I have a a Pioneer SX-434 radio/amp for my listening pleasure. The speakers are mounted high up, screwed to the wall, and are not easy to get at. I had to disconnect the speaker wires temporarily from the stereo and stupidly didn't mark the wires for positive and negative. Is there a way to tell which wires are which that doesn't involve ladders and me unscrewing the speakers from the wall? Thanks, Eric
