I am devising a rig that consists of a pre-amp, a carvin power amp (1000 watt) and two 8 ohm avatar cabs.(the B410 and the B115). What is the best way to connect the power amp to the cabs? Would it be ok for the amp if I ran it in 4ohm bridge mode for 3-4 hour gigs? I'm new to the world of "bigger" rigs and I want to make sure I connect everything correctly and that I get the most out of my gear without damaging it. Any help is greatly appreciated. Thanks.
