The problem is common to Cable TV subscribers. The problem is a "ground-loop".
Resolve this by making a simple Ground-loop isolator, using 2 75 to 300 Ohm cable adaptors connected back to back. or by purchasing from local Store.
-Try grounding the cable splitter to the screw holding the A/C wall plate, if any of these make a slight difference, contact the cable provider and reques..,make that "DEMAND" that they install a ($70) GLI (Ground Loop Isolator).
-Try to avoid, inexpensive Power surge bars, as all components connected to it share a small ground.
Connect the Sub-Woofer to a separate wall plug if possible.
