Anybody know the best way to run 2 amps on one bass knob? I have 2 Hifonics BRZ2100.1D's and they each have their own bass knob. I don't want 2 knobs for obvious reasons. Will a splitter work for these amps? local audio shop mumbled somthing about their powered by the amps and all this other jarble that made no sense so I figured I would ask here for help, Thanks
