To remove the subwoofer, you have to first remove the plastic panel on the passenger side next to the third row seat. It is much easier to remove if the seat has been taken out.
You will notice that the sub is attached to a large black plastic speaker box. The speaker is held in place by a large bolt on the back side of the speaker box that attaches the box to the magnet on the speaker.
The only way to get it out is to remove the entire box from the panel to get to the bolt.
Hope that helps!
the replacement is an 8" subwoofer

The subwoofer amplifier if not tampered with will be to the left but right next to the subwoofer behind the panel
The amp is right next to the subwoofer. They are both located behind the rear driver side panel.

remove plastic strip at base of back door, unscrew knobs that hold cargo net, remove third row seating and last remove side panel covering subwoofer. hope that helps its easier than it sounds. should need no more than a 1/4 inch nut driver I changed the subwoofer just last week and discovered some real fun stuff. If it is the factory subwoofer you will also have to remove the side panel and the subwoofer enclosure and remove the bolt from the back of the speaker itself. It's a pain, but only takes about one hour. I swapped it for just a regular 8" subwoofer and it works great.
