I have a RMX850 which I usually run bridged with an 8 ohm cab. Well a new band I'm going to possibly start playing with already has an 8x10 Ampeg cab at their practice space and to save me from hauling extra gear I'm probably just gonna bring my pre/power amp. I'm slightly worried the QSC may run a bit hot since it will be running on a 4 ohm bridged load. Does anyone else here run a 4 ohm load? and does you power amp run hot? Thanks!
