Thanks Tony...You are on the money it shouldn't have quit based on the volume level. It was REALLY weird. I was driving along and it literally quit. The deck was still cruising along, so I thought I had shredded a fuse. I get home and did the usual trace for no output problems...not one issue...there is a super small amount of sound from one channel in the rear outputs, but that is it...another deck from the garage powered the system just fine, but the RIO is dead.

Anyway, thanks again!
