Spoke with JC today when the sub was in continuous vibration/humming mode, but he couldn't hear it (frequency too low to pass through the phone line). I'm going to try all the suggestions here this week and if nothing then I'm going to take the 800 back. And just do without (can anyone tell me what the return policy is?)... I really want the sub, but I don't have the time to be spending hours trying to figure it out... the way I see it, with the money I've spent on it, it should work straight out the box, no?

I'm just frustrated... sorry.
