What kind of box did you use to get 158.9 db?

Used a duel port design kinda hard to explain but had a 1.1 cubic meter box not sure of the port cubic measurements since it was purely playing around with what worked best with a db meter....was tuned to 54 hertz but there was still plenty of room for improvement based on 1: Readings where louder with passengers door open which meant the box needs to be more precisly designed for the car and 2: We only ever had two amps running due to bridging issues at the time (audison have since brought out bridging moduels for their VrX series amps making life so much easier to access the power).
