First, does Martin have presets for the particular subwoofers you own?  Check this document out at the Martin website:

http://www.martin-audio.com/userguides/XTA/DP448/LOAD448.pdf

Mono vs. Stereo configuration depends on your available equipment and preference.  I tend to run my subs in stereo.

Which Crown amplifier model do you have?

Which Martin subwoofers do you have?

Knowing the complete chain of audio gear helps with getting better answers here on the forums.

With the XTA, you should be able to assign outputs as desired.  If running two subs and two tops, I'd assign outputs for each speaker cabinet, and feed each output to amplifier channel(or bridge amplifier if you're using amps that way).

If you want to run a mono sub configuration, assign one output on the XTA to be the subwoofer feed, and cable accordingly.  Depending on the amp model, you may be able to daisy chain patch cables if there are male and female XLR connections on each channel input, if not, you could make a "Y" XLR cable and split the signal physically.

Best regards,

John

An XTA DP448 has matrix routing internally. You could assign an input from the LS9 to be your mono subs (aux fed subs) and assign it to two outputs. You could then link the outputs to have same settings. Unlike the old BSS Minidrives that wouldn't allow for crossover overlapping the XTA doesn't care what each output is.
