It's under 20W in, but the power supply I have isn't enough for the amp. (Astron RS 35A) If it were in my mobile with the 270A alt and two batteries, it wouldn't be a problem.
Oh it's amp lights flickering, not my house lights heh heh. Undersized PSU for the amp...And those lights flickering is exactly why you really don't want to 'push' a power supply if possible. It means that the circuit supplying AC to that PS isn't capable of the draw that's being put on it. That leads to all kinds of complications. Any sort of 'pushing' is always a gamble. Just be sure you can afford to not win that bet...
