    2 things...

    A) Is it possible to run 3 cabs with one power amp? (thinking abotu buying 2 1x12's now and a 2x10 later but would like to run them all eventually)

    B) With QSC Poweramps, or any at that, if i want to run 2 8 ohm cabs together (making a 4 ohm load), is it possible to bridge a power amp into 4 ohms to gets it's maximum wattage and still ruyn 2 cabs? Or can I only run one cabinet when I bridge a poweramp? (if thats the case, would my only option be running the amp in stereo mode and putting one cab on each side?)

    A) It's possible, as long as the net impedance is 4 ohms or higher. That would mean, for example, that two of the cabinets would be 16 ohms each and the third one would be an 8-ohm cabinet.

    B) It doesn't matter how many cabinets the amp is driving, as long as the net impedance is 4 ohms or higher.
