[quote name='Bill Fitzmaurice' post='80220' date='Oct 27 2007, 07:54 PM']With the crossover on the stage you can't run an aux feed to the subs, which is far more versatile. Get the 6 returns or get a few extra mic sends, all you need to convert them to returns is an XLR gender adaptor.[/quote]
If you only have one monitor mix you could have the subs from an aux and the tops in stereo.
I'd probably go for a mono mix, (subs from an aux), and 2 monitors mixes. If you need more than that you'll be playing bigger stages and probably needing 3 or 4 monitor mixes anyway.
