So I disconnected the negative ground and waited 10 minutes, and reconnected and didn't do squat. So I went to the fuse box to see if I could figure out what fuse belonged to the HK amp. What I found was a disconnected power wire. Strange. I wondered why this was sitting there. There was another bundle of wires a few inches away that looked like could be connected..so I reconnected them, and the audio came back. Not sure how the wire could have come lose as there is a little indent lock and I haven't even opened the fuse box since I brought the car home 2 months ago.
