    Hopefully a quick question

    I'm about to build a box for my type-r that i just bought but I have a few questions. This is the first ported box that I am going to be building and I know kind of what to do but I kind of don't. First off,
    -whats a 15 type-r's xmax? (cant seem to find it)
    -how much port area do you recommend?
    I'm going to tune it to around 35hz. The next problem that I am going to encounter is that my box is around 3.5 cubes but it is going to be odd shaped (in a truck) so to give you an idea of what I am thinking here:

    10in
    ________
    / |
    / | 24inches long
    / |
    sub----- / |
    / 21in | 20in
    / |
    / |
    port- / |
    / _____________

    15in

    I just want an idea of what kind of port options i am looking at also. Thanks

    Shit.....well it didn't work....but anyway
    The box is 10 in on top, 20 high,15 in on bottom and the slant is 21 in, and 24in wide if that helps any (prolly not)

    MSpaint is your friend. Google sketchup is your best friend though. The Type-Rs xmax is found in the manual which can be found on Alpine's website. I believe it's close to 20.5mm though.

    Will probably be easiest to use an aero port...
