I am just now finally registering here, after ordering a basket and recone kit from Fi, I was just wondering if I can get some input on a box. Haven't had much luck finding ball park figures online really, but from what I remember when I bought this motor I think I was planning on doing ~4cu ft tuned to 30hz. That was a couple years ago though, so memory is fuzzy.

I can figure out on my own, that at 4.1 cuft after displacement, with a single 6" aero(on a side note, will run into my rear dash) I need 16.26" port length. My only question really is, is there another box(airspace/tuning) that I should expect this thing to prefer over what I have in mind?
