Us amps MD3D 2100wrms @ 1 ohm. the smaller the enclosure the more power it will require because the overall enclosure pressure will change more when the internal volume is smaller. I would say shoot for around 3.8 cubes. It does good anywhere from 3.5-4.3. AQ reccomends around 4.3 cu ft for SPL applications I think it was. And reccomended me 3.8 cu ft for a daily enclosure.
Yeah I'd say just go with the AQ 2200D. In a 3.5-4 cube box. You know you should ask what DJ thinks (the owner of AQ). He usually always answers to email and he should know, since he's the owner. lol.
