    Could somebody design me a box please? heres my information.
    1a. height: 15 Depth: 27 Width: 36
    1b. height: 13 Depth: 23 Width: 36
    2. two 12" kicker L7s
    3. 33hz ?
    4. 2000 watts rms
    5. 99 jeep grand cherokee limited
    6. subs back and port back but i want the port in the middle


    i need a new box because i got a new vehicle and the box i have is falling apart i gave two deminsions because the last time i did my demsions i ended up having to cut like 3 or more inches off the last box. also does it matter if the ap is on the top of the box or the side of the box heat wise? Thanks for your help

    here is 5 cubes at 36Hz with a 13.5" x 6" port (81in^2 area)...There isn't much of a difference between 33Hz and 36Hz.

    Top and Bottom - 36" X 27"

    Left and Right Sides - 25.5" x 13.5"

    Back Side - 36" x 13.5"

    Front Baffles - 15" x 13.5"

    Port Sides - 22.5" x 13.5"

    Short Port pieces - 1" x 13.5"

    Braces - 13.5" x 13.5" with 2" all around.

    Center port piece as shown...For most efficiency and smooth air flow please try to make the center triangular piece.

    Sorry it took so long Psycho.

    he didnt forget to add a brace he was just letting you know exactly where it was located. as for the 25.5" and 27" thing, you need to subtract 1.5" for the thickness of two 3/4" baffles for the internal dimension.

    Thanks azn also are the braces and the triangle part for box support or is that to help with the cubic or hz?

    picture the triangle as two 45 degree angles with an invisible wall between them. which would make for two ports. i see it as azn having fun haha

    the braces are for stiffness

    the triangle is smoothen out the port velocity
