I’m a low voltage integrator. I wire 200-300’ runs of rack to room RG59 and 14/4 all the time. I can’t tell you how many years it’s been since I experienced 60 cycle hum when wiring subs. Are you sure your amp is grounded?

I don’t run any sub with any of my personal two channel gear, maybe it would be more sensitive than typical AVR or Crestron amps.. try a long LFE wire or make a 100’ out of RG6 and find out.

Edit: Never-mind, just read the thread.
