The bazooka 6.5" amplified sub fits easily in the area above the spare tire, where the styrofoam is right behind the silver body brace.
Purchased about 5-6 months ago and it still looks new. It is next to perfect!

Amazon.com: Bazooka BTA6250D BT Series 6-Inch 250-Watt Class D Amplified Tube: Car Electronics
Amazon lists it for 189.99 brand new. Mine is very close to that so I am asking 130.00 shipped O.B.O. Here is another member's picture showing where it goes and what it looks like after installed:
Here is a picture of it still in the box:
