Hey guys diden't know where to post this so feel free to move it. I just purchased a QSC GX 5 Power Amplifier QSC GX5 Stereo Power Amplifier and more Live Power Amplifiers at GuitarCenter.com. and have a question about plugging a few things into it. (It has 2 channels.) On channel one I have a 475 watt guitar cab but its in mono. Next I want to run two Behringer B212XL 12" 800W Passive Titanium PA Speaker and more PA Cabinets at GuitarCenter.com. on one channel the second channel. How would I go about this and what wattage /ohms would the speakers run at if both ran on one channel.
