4 or 6?

i would personally go with 6 12's becuse it is going to louder than 4 15's becuse there are 2 extra subs there and just becuse the 15's are bigger doesnt mean they are better, anyways what looks better? 4 15's? yea that looks kinda cool but there are a lot of people that have 4 subs int heir cars. now 6 12's? there is somethin that you dont see all the time, and you kno that they are gonna hit hard even just looking at them.

ya im gonna have it built by the local car audio company. should i go ported or sealed in my dodge dakota ext. cab? i want to have it walled off.

I would go ported (im assuming that your not looking for much SQ anyway). Ported should be louder and will really get the air moving in the cab of your truck. It should be hella loud with the subs right behind the front seats.

definatly go with ported, its gonna give you the most bass with a ported ur gonna get about 2-3 more db's than a sealed,

ya alrite hey does like 38 hertz sound pretty good?
