[QUOTE="bbeljefe, post: 8192315, member: 655960"] If your sig is correct, you should first start looking at bigger wire and probably upgrading your electrical before you worry about moving hair. It doesn't really matter how much cone area and excursion you have if you don't have the electrical to allow your amp(s) to make that kind of power and 4 gauge isn't enough. After that, it depends on the subs you choose. Larger cone does not equal more excursion. For instance, an SA-10 has more xmax than an XD-15 so, three SA-10s will move more air than one XD-15, all other things being equal. In fact, an SA-8 has more xmax than an XD-15, so 4 of those will move more air than one XD-15... on paper. Another thing to consider is that in order to move hair with the power and cone area you're talking about, you'll have to deaden the hell out of everything in your vehicle and, the box will have to be optimized for the subs and the environment without respect to saving space. And that's likely to involve several rebuilds of the box. If you can't (or don't want to) do the build yourself I would focus on electrical, deadening and power first. Then I would look at two 15s minimum. That's a lot of cabin to fill before hair starts to move around. ;-) [/QUOTE]
