Yeah, I did. I don't have any pictures right now.. and unfortunately I am going up north a one and a half weeks.. I can get you some after then...

basically, search for the grommet under the battery tray.. another thread someone posted on how to access that.. that's to run the wire -> inside of the cabin..

after that, it isn't that bad. just lift up the carpet on the side (this is where I ran my RCA / power cables.. i had to remove the door sill and one of the side panels)

there's a spot to go to the trunk.. you need to take off those black clips.. they look like they are permanent but take a pair of pliers and get them out.. i mangled a few that I need to replace..

with pictures it'll be easier, but yeah. that's the general idea
