i guess i'd take 2 12W7's if you think you can afford it.....
but wouldn't that be a good 2-300 more than a single 13W7, or 2 w6v2's?
and i'm assuming that you have enough money to buy an amp too, cause the subs would be completely useless without an amp. I wouldn't buy subs just to sit around. if you can't afford an amp, i would just get cheaper subs than JL. RE is having a group buy with good prices,
http://forum.carstereos.org/showthread.php?t=56605 where you could get two 12 RE SX's for around the same price as one JL 12W7.
i wouldn't buy a hood, unless you are dropped, w/ rims, and are looking pretty good already, and that's one of the last things appearance wise i would buy. i highly doubt the weight difference would be noticible. hell i could probably go on a diet, and get better weight loss than a c/f hood.
