Yes have tried that. If my understanding is correct.... both cabs 8ohm, sending each side of the 1600w power amp to 8ohm give 800 per side @ 8ohms, so the cabs do not get their full capacity? The cabs are rated at 800w. Is there any technical difference running them on one channel each, as opposed to daisy chaining them on one channel, therefore giving a 4ohm resistance?
