I have a QSC 1602 and 2 GS112 cabs which are 8ohms each. I am purchasing a 4x10 cabinet (most likely to be 4ohms). Can I send Channel1 out to the 4x10 (using speakon connector) and Split Channel2 to the 2 different 112 cabs by sending 1 banana plug out to a GS112 and 1 speakon out to a GS112? Will this result in an impedence of 4ohms for channel2? Hope this makes sense.
