    i know this has been asked before, but im looking to fix this problem. i have a cerwin Vega ls-15 subwoofer and it sounds great, however , when i turn something on like a lamp or even my receiver i get a hum. i tried undoing the subwoofer cable(which is a monster cable line) and turned on the lamp- no hum. so my question is, whats next to check.BTW it is a 3 prong connection going into a wall socket.any help would be apprieciated

    Yeah - just use a different circuit. Maybe you can get away with using an extension cord for the lamp.

    i forgot to mention the lamp is plugged into an opposite wall. not on the same circuit. even when i plug stuff in on the same wall but different socket i get the hum. I also live in an apartment so wall sockets are at a premium

    Sounds like some kind of interference that is getting through the cable.

    My friend had the same problem and solved it by plugging the sub's power cord into a quality power bar.

    Different wall doesn't necessarily mean a different circuit.
    You can turn on everything............HT, lights, radios, whatever stuff is plugged in anywhere and flip off a circuit breaker or fuse and see what goes off. You may find out stuff in 2-3 rooms(not everything in those rooms) goes off at same time. One breaker/fuse may only turn off half the room, or just 2 things in the room..........

    it seems that its the wall socket itself. i unplugged the lamp that was connected to a wall switch and just placed it on a regular outlet...no more hum[​IMG] finally, some sonic peace
