    How much room does a port need to fire?

    Would 2.5" be sufficient between the wall in my car and the face of the port, firing toward the wall?

    Re: How much room does a port need to fire?

    That depends on the size of your port. If it's too big, your wall could slightly act as an extension of the port, resulting in a slightly lower tuning. Odds are, though, that there will be little to no audible difference. Pics?

    Re: How much room does a port need to fire?

    No pics, I'm looking into building a box now.
    I roughly have a total width of 52" from wall to wall to work with. The 3" flared port is going to fire on the left side of the box.
    The box is going to be symmetrical on each side, so it will be placed in the middle no matter what. I want to know if I should make the box 50" (1" between wall and port) in width or 45" (2.5" between wall and port).

    Re: How much room does a port need to fire?

    This is a good question I've always wondered this too, except more to the application of sealing off a trunk with a ported box. I want to do this in my next build but concerned about the space needed with the seats up...

    Re: How much room does a port need to fire?

    Is firing the ports up a possibility? That seems to be a very safe way to build truck boxes. You could use the entire width of your cab that way, too. Use slot ports if necessary.

    If not, a 3" port firing into a 2.5" gap to the side shouldn't be a big issue, especially if you place the ports as far forward as possible. I wouldn't fire them into a 1" gap. If you're set on firing aero's sideways, go ahead and build the box 45" wide, provided you're just building a daily driver.

    Slide the box over to one side more if you can, assuming its going to be centered for cosmetic purposes? Either that or redesign the box.

    That is how my current box is setup, with a 4" on top. Except with this box it is a whopping 5.25" on top and I plan on slimming that down to 4" or less for legroom.

    If not, a 3" port firing into a 2.5" gap to the side shouldn't be a big issue, especially if you place the ports as far forward as possible. I wouldn't fire them into a 1" gap. If you're set on firing aero's sideways, go ahead and build the box 45" wide, provided you're just building a daily driver.
    Just a daily, planning on bassracing 129's.

    I'm not set on anything, I just don't see how I can do port up if the top of the box is 3.5" and the port is 3", before flares.

    Current box:

    Why is everyone saying to fire the port up? I can do it sideways much easier.

    52"-45"=7"
    7"/2=3.5"

    Wouldn't you have 3.5" between wall and port?

    It looks like you're going to have plenty of airspace around a side-firing port. I say go for it.
