Here is an installation write-up by MOPAR for the 77KICK24 - 200watt 10 inch powered sub-woofer for the 2007+ Wrangler JK's.

A few notes:
1.) I had to pull the pictures out of this due to the attachment limits of the site. I know that this and all write-ups "Are Useless without pictures!"
If one of the site admins would be kind enough to let me know how to post the 900K .DOC or the 578K .PDF file that contains all 14 pictures - I would be more than happy to do so.

2.) I have not yet purchased this item so I cannot speak to this document for accuracy, but I thought it would be useful for our Santa list at this time of year

3.) My intent was to sneak a sub under one of the front seats to get a little more thump up in front with the top down, and remain stealthy to theives. I don't think this will fit in that location.

Enjoy!

 

Here is a zipped image of the 77KICK24 in the cargo compartment behind the passenger-side rear seat (reccomended installation location by MOPAR).
BTW pricing is $500-$600 including the remote amp that installs in the dash.
