I have a stewart pr 1000 which when bridged gives me 1000w into my 4 ohm shroeder mini 12+ which is rated at 500w rms. When i was testing this combo, I had a very large amount of volume going thru the cab a few times, but I never saw the clip lights on the poweramp even flicker. Given that the driver in the mini is angled its difficult to see how much the driver is moving and therefore it is perhaps easier to neglect it. So to be sure I dont blow the speaker should i have the poweramp volume maxed and then adjust the preamp volume accordingly or should i have the preamp maxed and adjust the poweramp volume only? I am guessing given that i want maximum headroom i should have the poweramp maxed, correct?
