Luc, using that equipment, the sub and speakers could be connected in two ways: first, you can run speaker wire from the amp terminals to the sub high level inputs and run separate speaker wires directly from the amp terminals to the M3 terminals(jamming both into the amp terminals and possibly trimming the ends down in size to help fit); second, you could run a speaker wire from the sub high level input terminals(again, jamming both wires in)out to the M3 terminals. These two connections are electrically identical. Note that subs don't have internal crossovers which might affect speakers connected through the sub, and the speakers will continue to run full-range.
