    Building a new box.

    Alright so im deciding to make a new box for my hdc3 12" aluminum coil. I want it tuned around 34 hz. The box I came up with (going in a 03 rsx type s) is 24x16x16. I was planning on doing a L port, with 43 inches of port (4 wide 14.5 tall). I am using .75 mdf. I want the port facing up blowing on the rear windshield. Idk what way to face the driver probably up. Does this sound right or am I just box illiterate? A guy gave me box specs for 23x13x23 which is 3.9 cubes with 34 inches of port which seems way to big and that small of a port seems like it would be a high tuning? This will be the second box I have built and im just trying to figure out more how to do it.

    Re: Building a new box.

    A big box with a low amount of port area will most likely be tuned lower unless the port is short.
    If it were my car I'd probably try sub up port back first.

    Re: Building a new box.

    Ive tried with the box i have and it sounds better with te port up, idk if its the angle of the glass? So 3.9 cubes isnt too big? I have been told 2.5-2.7 cubes. I have a box at 2.6 cubes and i fucked the port up. But 2.6 cubes barley fits, i could go a tad bit bigger but not much probably 2.8-2.9.

    Re: Building a new box.

    I would do sub up and port up and then use a baffle to seal off the cargo area....will work out nicely and get plenty loud and move a large amount of air if done correctly.

    Re: Building a new box.

    That depends on goals, enclosure design, power, port area, and available space you have to work with.
