Default Alpine MRV-1507

This amp is does some crazy stuff..

If i have the phase switch set at 0 Channel 1 will play but channel 2 is dead..

If i set the phase switch at 180 channel 2 will play but then channel 1 is dead..

I cleaned all switches with Deoxit but the amp still does this..

Any ideas??

Does this change if you set the crossover and input mode switches to their various positions?
