Calling all QSC amp owners............. Have any of you guys had any problems with running the RMX series amps bridged into a 4 ohm load for long periods of time ?? reason Musician's F&#%@ has the rmx 850 for $299. When bridged @ 4 ohms it says 830 watts. The closest thing in power(wattage) in a stereo configuration is the PLX 3002 which says 900 watts @ 4 ohms stereo. That one is $999. Why not buy 2 of the RMX 850's for roughly $600, run them bridged, and have 830 watts per channel (so to speak)?? Does this make sense to anyone besides me ?? Our mains are 4 ohm Peavey sp4's which are rated at 750 watts. I realize that the power ratings are probably with the power turned all the way up, but, with 830 watts surely 3/4ths volume should be plenty.
