hds215

so can anyone help me design a box for 2 hds215s, i need a box tuned to around 34 hz and 10 cubes before displacement. wanting a big aero port 8 - 10 in. going in a van so it can be big. anything is helpful

I am looking to purchase a Soundqubed HDS215 rated at 600w Rms. Any one know of a cheap monoblock amp that would do good with this sub?? Any other box tips would also be appreciated. soundqubed recommends 3.50^ft (4) 8" or (2) 12" or (1) 15" 56.0 sq" vent x 20" long. Does this sound good?
