Good point. I brought up the empeg EQ as DirtyDozen's a new poster. Assuming you didn't want to control front & rear EQ separately, couldn't one use the rear outs to the sub's amp (bridged at the amp) & use a trim pot mounted in an unused dash location to control the sub level?

Also in the diagram shown, just how are the amplifiers '(optional)'? Speaker level through RCA's? Weird.
