Subwoofer positioning?

[k3n12ock]

So this is the design I came up with for (4) 10s in a sealed box. As of right now, I am gonna do either;

a) 3 subs firing up, 1 sub firing to the right.

or

1 sub firing left, 1 sub firing to the right, 2 subs firing up.

Box will be sealed, for now. In box a), I may add an 8" aero to the right side. In box , I may add an aero in the middle of the top 2 subs. (Hence why there are 5 holes in the box design)

So my question is, which do YOU think would be better in my 05 xB? I know some of you are gonna say "do both and let us know" but I don't want to, ha.

Lastly, subs are gonna be either sd10s, strato 10s, or sa10s.

Two 12s ported subs up/port back, besides two 12s would be cheaper for a particular line of subwoofers.
