I want bandpass, because all the articles i have read have suggested you get the most efficient amount of bass / wattage with them. I want to feel my bass. As far as i understand it, i cant get that so chrisp with any of the other setups. And i dont want to play with putting the sub on the back of a seat, or anything like that, i just want to be able to put a box in, and be happy.

by all means make suggestions:

i currently have 4 tweeters and 4 "normal" speakers. I think. This cant handle as much bass as i want, and i want muchos more bass. I want it punchy, and as far as i have read, a bandpass would be the best for this. I dont realy care too much as far as frequency limiting goes.. anything a bit higher, the normal speakers can handle anyway.. i think.

my mate has a bandpass, and it rox. Anoyher one has a closed box, doesnt sound as good in my oppinion.

Anyway, a good sub / box combination premade anyone?
