I'm running a Brahma MKIII in a sealed box being powered by a Elemental Designs NINE.1. I'm finishing the box this evening and I'll be mounting the sub except for one problem. I'm not exactly sure how I want to wire it all up. As most people know, the Adire recommends 600 watts which "depends on the application." Obviously I want this thing loud but I don't want to damage the woofer.

I forgot to mention the sub has duel 4 ohm voice coils.

 

Well, your options are wiring the sub to 2 ohm or 8 ohm. At 2 ohm, your amp will push 900 watts to the sub. At 8 ohm, probably less than 400 watts. I would say run it with 900 watts and just be careful with it.
