Just an idea.. you could be like me, and go for JL 18w6's. Originally i was going for 6 10's because it has more surface area than 3 12's, but uses the same amount of enclosure space. But then i realized the 18's.. they very small box sizes at 1.75cuft. That's the maximum recommended enclosure size. I have 2 of those in my car in a box that is a little less than 4 cu. ft. If u look around, you could find one for sale. Just my 2 cents.
