well if it is an he2 or hx2 obcon makes a box called the godzilla, which is made to speck for those speakers...... i hate Q logic.. their boxes look like shit.... especially their badpass boxes with those 1980's lookiung designs on them.....


try obcon, subzone or an independant builder.....


BTW, i like sealed the best myself, badpasses are effiecient but oinly at one range of sound.... it wont sound that good, and it might slam on one song but sound shitt on another.... it all depends on what the box is tuned for.....
