    new box builder here..

    ok i finnaly planned this box but its my first if someone could check this cus i used a port calc./bass box pro/calculator and got different numbers....

    external dimensiond= 4.75ft x 1.7ft x 1.3ft - ( .54ft x .54ft x 4.75ft) = 9.1ft3
    the minus part is for a indent in the box for it to fit the truck
    so 9.1ft3 - .16x2 for the displacment of 2 12'' sx = 8.78ft3

    now the port
    i want to do a square port and if thats a bad idea ill go slotted but heres what i got
    .59ft x .59ft x .43ft = 37 herts
    i also what to make it able to pull out and put in a diff port of
    .59ft x .59ft x .54ft = 35 herts
    and 1 more for comps
    .59ft x .59ft x .14ft = 45 herts

    i also will have some port support and mabye some internal supports

    so with the ports vol and all im lookin at a finish of
    lik 8.7ft3 tuned to 37

    is that way too big for 2 12'' sx given 2400 watts???

    if so is it at least correct cus i can tweak the dimensions a lil to lower the volume....thanks for ur time guys! if needed i will pay to get this checked but i gotta wait til friday when i get paid....



    Current system:
    03 Ford Explorer
    iraggi 300amp alt (on its way)
    Red top under hood and deka 9a31 in back ( on its way)
    stock mids and highs
    Pioneer Z110bt headunit
    1 18'' TC9/Audioque In 6cubes tuned to 32hz
    Audioque 3500D
    Handles the lows just fine

    That box is WAY too big in my opinion. That's more than double what RE recommends. You may want to rethink a box that size, especially with that kind of power.

    Re: new box builder here..

    I can't comment on the dimensions. I can say that 5 cubes total for those sub would proably be right on the money. I have my 2 15" SXs in ~7.4 cubes and it's awesome.

    Re: new box builder here..

    Do 5 cubes NET @desired tuning. AT LEAST 60 in^2 of port. Don't forget NET is the INTERNAL volume AFTER port and sub displacement (don't forget to add .75" to port width for the wall made out of mdf )

    lol ok
    dimensions- 57'' x 20'' x 16'' - (6.5'' x 6.5'' x 57'')= 9.1ft3

    .16 x2 for sub displacment = 8.78ft3

    port= 7'' x 7'' x 5.21'' = 37herts
    7'' x 7'' x 6.5'' = 35 herts and
    7'' x 7'' x 1.65'' = 45herts
    port displacement = .145ft3
    port area = 47ft2 - that is probably too low huh?

    final vb= 8.6ft3
