OK, i've got my sub on it's way here, how do i wire a JBL 1200.1 to a XXX 12, and also the box will be ported and i going to need a crossover, or i dunno, it's some kind of filter that the 1200.1 doesn't have. I don't really know i just remember hearing someone say something about some filter that a 1200.1 doesn't have that it needs for boxes tuned low
