    I have mine in about that same box with about 800 watts going to it. The B's are very picky about box size is what I heard. Need to tune it down a little though. Mine I have no idea what it is tuned to but probably around 30, it doesnt hit the highs very well but the lows go LOW. Just build another box and go as big as you can. 3.5 after displacement would be alright, tuned to about 30 or so.
