Sorry to hear that you are having issues. I am not sure about the clicking issue but from what I have read it may be that you are overtaxing the unit. But again, I am not too sure. Let the unit play for a hour and put your hand on the top of the unit. Is it hot to the touch? If this is the case you may be pushing it too hard or you do not have proper ventalation. You may want to look at two Outlaw M200 amps to power your fronts (200 watts at $299 ea). Just a thought.
