Hey guys new to this forum and just looking for some info. I have a BL 15 on a SQ2200 sealed off in my car. The res fq of my car is 37hz and im looking to increase my spl #'s. What is the recommend port area and port area per foot? I was thinking about using 3 4" PVC ports. Does anybody recommend something else?
