I have a GK rb1001 ll. The guys at Gk told me that there is no way to bi amp without a GK cab. I thought I could simply make 2 seperate cables using the opposite speakon pins and then run them to a high and low cab. The tech at GK said that the 50W section dedicated to the high end was not designed to drive a cabinet, only a horn. Has anyone done this, my way? I planned on using a 4x10 for lows and a 2x10 for highs. Please help.
