I am trying to install an amp and sub in my trunk of my 2000 Grand Cherokee. Is anyone familiar with a good hole already in the firewall? preferably on the passenger side since that where my battery is.
Or
If there isn't a hole, how difficult would it be to drill through, under the carpet, underneath my glove box? I've been looking, and poking around all day, the best i found was a rubber grommet in my floor board that lead to behind my wheel well next to my exhaust, not exactly the best spot of my power lead...

EDIT: sorry I just realized this is for a grand sorry I really don't know for a grand.

Another thing you might consider is pulling the trim at the base of the door areas and lifting the carpet. There is already a wiring harness that follows that pathway that goes to the back.
