I'm running an SVT-IV into an 810AV mono bridged with a 4 pole speakon cable. I understand you need the speakon to be specifically wired. I have read so many threads on the subject but I just don't understand. It should be wired for +1 (positive) and +2 (negative) on the amp end. The cabinet end should be wired in the standard fashion, which is +1 (positive) and -1 (negative) right? But with a 4 pole cable what do you do with the remaining -1 and -2 connectors on the amp end and the -2/+2 on the speaker end? I'd really appreciate it if someone could dumb it down for me. Currently the cable is symmetrical with black 2+, red 1+, blue 2-, yellow 1-.
