ported box

[madscientist 0]

I am toying with the idea of putting 2 12" SSDs in a ported box. My original plan was to seal them, but I don't know what kind of output I would get. Could someone help me design a ported box for these subs? I am totally new to ported boxes so I don't know where to start. I'd like to maintain as much SQ as possible and gain as much output as possible. Dimension wise, my trunk could accomodate a box 39" across and 17" high. Depth is negotiable, depending on the size of box needed. Thanks in advance for the help.
