    depends on the type of car? how much power is going into it? ive been told to tune around 32-35hz, don't think there is that much of a diffrence between 30-32 hz, but these subs love low notes so it will probably be perfect from your listening prefrences....

    either a 1996 monte carlo (2dr, fold down back seats) or a 1984 buick regal (2 dr, no fold downs ) and a bx2005d @ 1 ohm

    should be fine. I think thats a slightly small box though. They would work alot better in 2.25-2.5 each

    Stock speakers?

    It'll get loud, sure...but that's about all you're going to hear.

    4 cf ported box, tuned to 30 hz
    that will sound good.
    5cu ft @33hz will hit way lower.
    6cu ft @30hz will hit like mad low tones.
