I'm trying to avoid buying a very expensive 10 gauge 50 foot speakon->speakon speaker cable, so . . . In one club we play, the daisy chain run from the Left main cab to the Right main cab is 50 feet because it has to go up across the ceiling so drunk people don't trip on it. My Mackie 1400i manual says . . . Gauge 4 ohm 10 120 feet 12 75 14 48 16 30 "Remember that the actual run is twice as long as the physical length of the run." It's a 4 ohm load. I'm supposed to add the amp->Left main run to the Left main to Right main run for my physical run, right? Then I'm supposed to double that to calculate the "actual" run? How bad is it to splice speaker cables? I know how to solder and have electrical tape and shrink tubing to protect my splice. What happens when you mix gauges? Like if the amp->Left main run was 16 because that's short and the Left to Right run was 12 because that's long. Please help!
