Going through my fault isolation steps:
-left tower speaker inop. Makes a humming noise when volume is at zero but does not work at any volume stetting, with accessories or engine by running regardless of throttle position.
-swapped tower speakers, no change. Wetsounds sent me a new HTX-4 DSP amp, still didn’t fix it.
-exposed as much wiring as I could and did a visual inspection, no issues. Wire continuity checks out on a multimeter. Green wires are for the left speaker and blue for the right.
Can a bad ground affect one speaker and not the other? Anything else I need to check?
