The loud humming could be caused by a cable on the input that is not grounded. It could also be caused by some sort of power supply failure.

Disconnect the input and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

If you can test the capacitors in the power supply you might just locate the issue. Would need to remove and use a cap tester. Bad ones can look just as good as new ones.

Speaker makes a rather loud humming noise.


You can go buy a audioquest SUB-X subwoofer cable with a additional ground wire on it an connect the ground cable to the ground slot of the receiver an the other end to a screw on the sub or into one of the high output terminals on the woofer if it has them an this will take that humming sound right away but the cable is around $90

Humming sound when on/off


humming sound when on is usual if the volume is turned up.
humming sound the same when on or off could be transformer plates fluxing.
if loud recommend replacement of power supply.
if ok then recommend unplugging the device after use.

The power fuse blows as soon as the unit is plugged in


There is a problem with the amplifier within the sub. Many of these units never completely turn off. They are often set to automatically startup when a signal is detected. This may be the case here. The loud hum as a defect in the output amp section. At this point you probably have a blown amp section. The "protection" for this is to cause a dead short that will open up the fuse. This unit will require service. It is unlikely that any service info is availabel to the general public either.

The fix could be simple, but without seeing the unit, I can not state that for sure.

Keep us posted.
