Earthquake amps are great for SPL, they are fairly cheap and not all that clean. I had 1 of of the first d2's, I worked for a earthquake dealer back in 97-98 and it was given to us by the rep. A generic black heatsink with a sticker that said "digital" on top and along the side it said made by Earthquake of San Francisco. Studly little booger benched at over 1300 watts. To answer your question of 1 or 2 amps, I would personally go with 1 large monoblock. Series em up and parallell down to 2 ohms.
