    ok well most people dont use PA subs in the car audio world but i do... needless to say i built a 10 cuft 4th order first with the sub chamber at 5.5 cuft and 8 in port on the 4.5... sub got HOT fast. so then i connected to 2 chambers and left it like that. still all movement no sound.. then i sealed the box totally with 10 cuft and still nothing. was about to give up totally. After all that i built a wall for it in my van and in roughly 60 cuft 4th just messin around the sub started to work amazingly! im very satisfied with the overall build of the sub and will be buying 5 or 6 more VERY soon to finish my build!
