I have a Kenwood 12inch KFC- **** (can't remember the rest) it "says"
750watt; I know it aint true, anyways long time ago, when I originally build
the box, I built it with a slant so it could fit snug behind my back seats;
now in my new car it ain't so snug, I think it'd be best if I went back to
the good old cube... Plus in my original enclosure I used nails, I think it
aint as air tight as I'd like... So.... I can't remember nor do I have the
instructions to know exactly what volume to box should be... Can anyone help
me out?? point me in the right direction?? Or does it really matteR?? can I
just bang together a box to fit my needs/boot space and forget about the
volume etc??

Goto kenwwoods website. Most of the time they have the specs which
should tell you how many cf you need.
