A disadvantage of the EP subs is that they don't have high level outputs so you can't connect the speakers to them. As a temporary workaround set your speakers to large and connect the speaker wire to the sub low level inputs then cross the sub at the speaker -3db extension point. Your going to have adjust the sub volume to get it right. Permanent workaround is a new processor. A mid-term workaround is to use a sub with high level outputs so you can set the crossover where you want it.
