hi there, im having a bit of a problem with my ice system, after recently had an alarm fitted my big amplifier (600w max) is shutting down when turned up to high volumes. my other two amps (300 w max each) still work fine though, just wondereing that if when alarm was fitted drained more power from battery and therefore, when turned up, amp has none left?? would a power cap and/or uprated battery help this?? cheers
