    First, if the box is 2' x 2' x 1.5', then its not going to be 6 ft^3. Displacement of wood/sub will make it smaller, especially if you want it ported (you have to then take into account the displacement of the port as well).

    edit:


    Is 3x2x1.5 your max dimensions? Every inch helps, and if those are your dimensions you will probably be able to barely fit a 6 ft^3 (internal) ported box into your trunk.

    Re: 18" FI Q Enclosure

    With those measurements, using 3/4" MDF (which is recommended), the max gross space you can get is 4.83... which is barely enough for sealed... and when you factor in the sub's displacement, you're left with a measly 4.59 cuFt.

    I say either get more room, or get the 12, or 15.
