For $300CN, yes.
For that kind of dough, I'd check out the Infinity Basslink or a 10" Powered Bazooka.
BTW, there's no need to cut the rear deck to mount an 8" sub. There's already a hole. Take a look at the underside of your rear deck on the passenger side.

You only need to make a baffle out of some MDF and drill 4 holes.
