Which would you recommend for a yaris sedan single 10 inch or 12 inch sub

[Alien Mantis]

Looks to me like he has TWO of those subs in that box.

( from looking at both pics )

And the box is ported. Those look like 12's ?

Since those subs are on opposite walls, are they wired for PUSH-PULL?

( or do you have internal walls between them? )

Interesting setup.
I think I would pass on the window decals though... don't like advertising to thieves.
