I had a subwoofer box installed in my Screw and now I have no place to stash my jack I installed the amp under the passenger seat so that's not an option. I was thinking about under the hood, has anyone done this and if so where?

 

Yep, been done. It was posted here a while back. Search a bit and you should find.

 

Dupuis has a nice rig setup to relocate his jack under the hood. Crossreference his user name with search and ye shall receive...

 

I relocated mine to my garage and bought AAA.

 

Get you a tool box thats where I keep mine

 

I like the one suggestion of inside the spare tire. that was posted on a link i found after searchin for dupois or whatever
The only thing i would add to that is a large ziplock bag to keep it dry and in good shape. and maybe wrap them in something like an old shirt to keep them from rattling too much back there.
