Yep, I searched. Sorry in advance. For some reason I am getting the humming sound through my subs occasionally. Both cables are new. I am running a splitter. I have noticed that sometimes the subs just fire up BUUUUZZZZZ and if I unplug one or the other or remove the input cable it is gone. Also, one specifically does not go always go into standby. This morning about 3 am the 12 kicked in. My wife has always been cool about my HT gear. I better get this resolved if I want it to stay that way.Where do I start? I am running Belkin Sub Cables and then this guy "Mediabridge - Premium RCA Y-Adapter 1-Male to 2-Female for Digital Audio or Subwoofer".
