PSW650 turning off with dial AND humming noises with shock!
1. Whenever I adjust the volume dial on the front of the PSW650, the sub turns off for a few seconds. Is this normal?

2. This problem is unrelated and has happened twice now. My sub is on a metal cabinet with everything else since I have no space in my dorm room. But with this dry winter weather I can get shocks from touching the TV or cabinet... then the subwoofer turns on and starts a humming sound. If I turn on a source to the sub then the hum goes away. In a few months the weather will get better and I'll be moving to a larger space... but how bad is this in the meantime?

I do not know what to say - did you say a metal cabinet.
Never put a sub inside ANY cabinet. Sounds like it is messsed up. Turning up or down the volume and it shuts off - that would be a big not normal.:eek:

The cabinet isn't solid. It is one of the heavy-duty wire mesh frame ones. So the subwoofer isn't surrounded by anything that would mess up sound. It just sits in the corner, but the cabinet goes up around it to hold the TV and other stuff. But I think that the metal can conduct static electricity since the posts are relatively close and that the subwoofer is either giving or receiving the shocks.
