I have 2 pre amps and i wanted to try and run them stereo with the crown xti2000 using an ABY switch in the front to switch between the A/B channels or turn the switch to Y and run both channels. The crown can handle 800w at 4ohms each channel and my cabs are rated for this. Will this work or will I encounter some issues? (i.e. Overheating, Severe clipping, Power Shortage, ...) any advice would be greatly appreciated. Thanks.
