So I have a Fi 15 09 Dual 1 coming in the mail and I thought why not get the box built and ready.

What do you guys suggest, I usually listen to rap and like my low lows but I want this thing to pump!

I tried to use http://reaudio.com/speaker_box/LPort_Box_Calc.html But I didnt know the specs I should enter in order to do this.

Do you guys suggest I have this facing backwords with the port facing backwards or face it forward and have the port facing forward? and just put down my seats when I drive?

enter in your max dims height and width and work from there adding depth as needed to acheive desired cubic feet
check fi's recommended enclosure size and use that as your starting point for volume
just try to use enuff port area 12-16 in^2per cubic foot
example 2.0 cubic feet net 24 in^2 or port area (2" x 12" ) etc...
that calc will also automaticaly use total height as height of port so just play with port width till all goals acheived
