I have a 95 dodge ram extended cab that i am taking the rear seat out of to make room for my sub. I was wondering if someone on here could help with a box design for this truck/sub combo.

head shaking lows is what i am after as this will be an everyday setup.
Not to worried about spl but i do want it to be a loud system.
Not sure which way the sub should be facing and what way the port should be facing.

Any help would be great.

 

in a truck go sub and port forward, and for that woofer go 4 cubic feet with 64 sq.inch of port 16 inches long, tunes to 40hz(dont worry about the high tuning it will get low)
