|Humming||Remove or insert ground screw
Put Antenna Ground Isolator in incoming antenna cable
Try to plug the subwoofer in the same electrical outlet which is used by the other system components or the same electrical circuit
Verify that the electrical wall outlet is properly grounded and that the polarity is respected
As a last resort we suggest, is to use a Universal adaptable three-prong electrical plug
