2 cu ft per 12" sub, use 4" ID PVC as port material for each sub and if this is for SPL, tune the port lengths to about 55-65Hz.
I'd probably consider a V shaped box facing up, to accomodate the number of speakers or aim them forward at a quarter-wave distance from the dash for SPL based on port frequency.

kfc? you sure those are subs and not white meat chicken? *grin*

every time I see someone post "bump" I get the urge to throw them off of a cliff..
that crap is so irritating. If you're going to post, at least post something worth reading through the thread to see. My friggin' dog could come up with something more useful to say than "bump."

besides, what the fsck are you bumping this thread for? It wasn't even your thread...

it was dead.. because he'd been helped and there was nothing more to say.
that was why I wondered why it got bumped lol

usually people do that when they're impatient, or nobody is responding
