    need help.

    i need some help, some one tossed me a box plan but it's to deep.

    Here is the design that I did for my buddy. It is tuned to 40 Hz

    This is for a dual chamber box. External measurements are 14" tall x
    31.25" wide x 30" deep.

    (2) 30" x 31.25" <--- top and bottom
    (2) 13.25" x 12.5" <--- Fronts
    (3) 29.25" x 12.5" <--- Sides and middle
    (2) 12.5" x 11" <--- Inside Port wall
    (1) 12.5" x 29.75" <--- Back


    i need it to be 25" deep. how would i go about resizing it. i can go tall and wider, i just don't know how to do it and have it the same all aroundsize and tune.

    and should i keep it tune like that, it'll be in a jeep off a pg t1200.1 i like lots of spl and like to hit pretty low. if i need to change the tuning how do i do that also.

    thanks.

    35" wide x 25" deep x 15" high will get you the same numbers...

    top/bottom: 25" x 35" (2)
    sides: 25" x 13.5" (2)
    middle: 23.5" x 13.5" (1)
    front: 13.5" x 28" (1)
    back: 13.5" x 33.5" (1)
    port: 13.5" x 14" (2)

    This will give you 2" x 13.5" ports and tune it to 38Hz. The ports are on the outside edges and the middle is not seen, hence the single front baffle.
