Just curious what you have in your stock jack location if you have lifted your X. Also curious where to put this topic? I put it here because I moved my ARB compressor to that location. I used to have it mounted like this:

because I didn't have speakers back there and never thought I would again.
Well, I had a few days off of work and decided to change some things up a bit. (and put my stereo back in the X, driving with no tunes sux)

Took it out of there and put it...

There.

Had to trim the tray a little on the underside but nothing a dremel couldn't fix.
So what's in your's?
