I have an Athena Subwoofer (not sure on the model, I'm at work) and it won't work. I've tried two different RCA cables but nothing, no bass at all. The thing that worries me is that if I plug the power into the subwoofer, plug one end of the RCA cable in and touch the other end with my finger, it doesn't make the buzzing sound it used to. I've noticed that the RCA jack on the subwoofer was loose and I had to tighten it up. Could it just be that the jack is disconnected inside or something?
