you could have a bad grounding problem or the cable is becoming a antenna.

Hello,
Welcome to the Forum, I'm sorry there's a problem with your system. A few basic trouble shooting items to check. What happens to the humming if you disconnect all of the incoming cables/wires (not the AC power cord, of course) from the sub-woofer? This will help determine what might be the cause. If the sub-woofer continues to hum, give me a call at 1-800-377-7655 extension 891 and I'm sure I can help.
