Question RE Corbeau Baja RS rear seat and subwoofer

[Oakland Bronco]

So I'm going to put in a family cage, with Corbeau Baja RS seats tied in. Two questions:

What type of space will I have between the floor and the bottom of the rear seat?

I have two pairs of 6x9s in the rig, but it is lacking some bass. What are you guys using for a subwoofer? Any feedback on bazooka tubes? To be clear, I'm not looking to set off car alarms or be heard two blocks away. Just trying to fill in the missing low notes.

EDIT: Anyone have experience with flat subwoofer enclosures, such as this:

I don't know about car audio that much, but I do know these guys are tough to beat their prices.

I have this 8 inch powered sub under my front passenger seat and am very happy with the performance, filled in those empty notes you are alluding to.
