I set the sub crossover knob to bypass and the trim to flat. Also, turn the volume knob on the sub to around the 7o'clock position for initial setup. (all of this is explained in the pamphlet that comes with the sub)

I also use Small on all speakers with 80hz crossover on the receiver. However, I'm been experimenting with setting my M60's to large.
