Im getting one kapa perfect 12.1 and Im buildin a bandpass box to infinity's specs.. I will be using a JBL 180.2 amp and I heard that you need to use a sub sonic filter when using a bandpass box with JBL amps..?? and where can i get a sub sonic filter..also I heard that if the box is built to the subs specs I do not need a filter?

Bandpass is horrible. You have a great sub that has good SQ and SPL and you're gonna put it in a bandpass box and ruin all theat SQ. Go ported before bandpass....PLEASE!!!
