I purchased a new JL1000.1 to power my sub which is replacing my weak alpine amp and now after a few days of sitting, my 3 optimas are draining down. How can a amp which appears to be in the off mode keep draining my batteries? The head unit is totally out and no indicator lights are on from any of the other amps. Never had this issue before installing the new amp. Any advise would be much appreciated.
BTW, I did add another blue top at the same time but that is the only other change.
