    box for 2 digital designs 9515's

    hey guys im trying to design the best box for my subs and i dont have too much room to work with.the box is going into my 1995 honda accord ex 4 door sedan. for now there going to be run off a 2k amp but im hoping to get a bigger amp when i can make some more cash.



    the dimensions of the box is W33" x D28" x H14.5"

    the subs will be facing upwards and im deciding if i want to but the side by side or having them on a angle. i also would like the port to be facing towards the inside of my car ( maybe a aero port?? ) but i would like to know whats the best port size. im thinking the box should be around 34hz ???

    any other tips and helpful advise will be extremely appreciated

    Not enough space for 2 9515s, maybe 1...

    Not enough space for the HUGE text either...

    I'd run one ported. You'll be choking two 15s in that space

    EDIT: Oh, and if you aren't going to be blocking the trunk off from the cabin area, face the sub and port away from you.

    Or do this, I'm not a trunk person, but I do know that towards you isn't the way to go in 95% of cases.

    After sub,port,bracing you will not be able to build a proper box for 2 9515s. I barely fit a box for 2 9512s in my Concorde and my trunk is wayyy bigger than yours (I used to have a 96 Accord Ex).

    You simply do not have enough room to run both. You need to totally ditch that idea.

    That's before displacements. You need around 10ft^3 before displacements to end up with ~8ft^3 for those subs.

    Sometimes less is more. I would be willing to bet that 1 15 will be louder out of your trunk than 2. I also hope you have the electrical support to run 2k watts. Stock Accord alternators are very weak.
