    New setup! 2 12" bandpass box? Just looking for some info.

    So i just bought some used subs. JBL 1200.1 amp and 2 12" infinity perfects 12.1 in a bandpass box? the only thing im confused on is the ports are on the back chamber for the subs and they share a sealed compartment from the front firing side. I though bandpass boxes were suppose to be ported in...
