Subject 12'' Punch Hx2 should I port them or keep them in my sealed box. My problem has always been trunk space, I own a Honda and well you already know. My current system sounds decent, the box is chambered 1 cubic ft. per sub But I know there can be more shake. Oh and Ps if I do decide to port = im on a tight budget what so you think about 4'' PVC for the mean time. im thinking port noise
