Re: Aftermarket Navigation install into an 05 WK Grand Cherokee? Ordered Wrong Part?
that's just routing and fab work. there are all kinds of tutorials to be able to do that. as for the tweeter install in the door panels i assume you are going to place them in the plastic panels by the mirror? if so you just pop off the doors pull the pieces drill from the inside out and mount them, and depending on where you place the xovers for the tweeters you might have to run additional wiring.
Not a overwhelming task you just would have to do some research.
I would assume that all of the items you want to put have installed would have tutorials or write ups right here on Jeep Garage.
