If you're currently using an unbalanced cable, then you should switch to a balanced one (they're designed to avoid problems like this).
Otherwise, try and route the cable away from AC circuits and other noise sources.
And, if your cable has to cross or be near AC power lines, try and have it cross them at right angles; DO NOT run an audio signal line parallel to and near an AC power cable.
Also, specifically, keep it away from fluorescent lights - their ballasts are notorious noise sources.
Would using a CMX-2 on the subwoofer help with this, do you think?
Old post but wanted to touch on the ballast rfi issue brought up & unexplained noise in the system .
If your running cheap quality or defective digital ballasts within HID or Florescent lighting RFI can enter the system thru several paths , any loose or damaged cable connections, open cable leads or even thru unused rca & balanced in's & outs on your gear , i use shorting plugs on all my unused in's & outs on all my gear & on unused ports on the cable box's .
I have a system in a home that has 28 600 watt digital ballasts in the barn & any unused in or out anywhere in the system will let rfi into the system & mess up the interactive cable as well as an audible hiss , shorting plugs stopped all my rfi issues instantly .
