Thanks for the tip. I did try something else last night. I hooked my sub outs from my headunit into the rear outs instead. I thought maybe I damaged the rca outs from the headunit. When I did this, it acted the same way. This either means the headunit is not the problem, or the front, rear and sub rca outs on the headunit were all damaged.
I'm hoping someone has had a bad ground or accidental disconnecting sometime. If so what happened??? Thanks.
