Ok, So I have a jbl PB12 that when I turn it on all is does is hummmmm quite loud. It is not connected to anything but power. I am pretty new to the audio/electronics world (I know computers) so I am not sure where to look. What should I be looking for? Can anyone please help me. Thank you.

Ok, we need some info here.

1. Is this subwoofer new to you?
1a. If not new to you, has it worked fine in the past?
2. How loud is the hum?
3. Have you tried running a signal to the amp to see what happens?
