If its a trunk car people usually fire sub and port back. If its a truck the most recommended is sub up and port back

Sealed box: 2-2.6 cuft
Ported box: 2.8-4 cuft @ 28-33Hz

so 4@ 32 might be good

higher hz = higher notes.

With a larger box like that you get alot better low end. but you could keep it at 4 cubes. probably wouldnt notice much a difference

Qs are supposed to be good in big boxes with low tunings, but i dont think id go outside the manufacturer's recommendations

get into home theater and you can throw a 15" in a 8-9 cube box tuned to 15hz or so and you will hear so so so much!

ive actually been thinking of putting my 18 in a 15 cube sonotube, but if i did do that i wouldnt be expecting the greatest results on music.
