I'm wanting to buy a Carvin bx1200, and run it in a stack at full power for my band. I have an ampeg 4x10 now with 500 watt handling and want to add an avatar 4x10 to complete the rig. One question, how would the wattages be split if i run the head at 4 oms bridged? (1200 watts) would it be 600 per cab? Will this fry my ampeg?
