Can someone explain how and why this is done? We are going to be hooking up our pieced together PA and we have a couple eqs laying around. We are running 3 monitors and 2 mains, with 2 subs. We are running three amps. One for monitors, one for mains and a large amp for subs. Also the amp I believe will be run in stereo. WIth one sub per side. Pete where are you!!!
