S Sigs is correct... however if the wires connecting your amplifier/Avr to your subwoofer ae not connecting properly, this might also happen. First check the connections.. then the capacitors.

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Get a ground-loop isolator, it should get rid of the humming sound.
