Connecting two Gallien-Krueger MB212?

I liked using dual input combos to daisy chain, or use effects loops, or an aby or line selector pedal. I have a Boss LS-2 to do that.

I'm guessing a good old Y splitter would work just fine.

I also have the MB212 ii and don't think I'll ever have to run it hard..... they are pretty loud. But If you need more...... as far as i know the MBP extension cabs are pretty much just a powered speaker. I would think you could go out of the MB212 xlr to a powered PA cabinet for more volume.
