Dan, you should set all speakers to "small" on your 1300 which will then send material under about 90hz from all channels out the low level sub output. A coaxial cable is used to connect the sub out to the low level input on the EP350, which probably is best located in the corner closest to the M60s. The crossover on the EP350 is unnecessary,since the 1300 is handling all crossover duties; so, it should be turned up to the max to get it as far out of the way as possible. The speakers would be connected to their respective speaker terminals on the 1300, using regular speaker wire.
