I have a GK 700rbII 480 watts @ 4 ohms. I have a B212 8 Ohm and a B212 4 ohm. I know I cant run both at the same time or it will take my ohm load too low, but on the 4 ohm cab, if I unhook one of the speakers in the cab ( essentially making it a 112) wont it then be an 8 ohm 112? Would this work very well or should I just sell it and get another 8 ohm cab?
