I am posting this here, because the audio/video section doesnt get answered very much, if at all.

I am going to be running a power cable from my trunk to the battery, and I dont want to drill any holes, or run it outside of the car. is there any gromets or holes in the fire wall, I can pull a 6 gauge wire thru without drilling. any help would be appreciated.

 

hmmm...
what about where the wires are pulled thru for the dash accesories (stereo/dash panel, etc)...there should be some play there where you could squeeze some extra wiring thru

and to make it all nice and neat, just put all the wiring under the plastic side well things... (sorry, loss of words)....its at the base of the doors

and i know when i had my subs installed, thats what they did... im not sure how big the wire was...the average amp wire...

 

do you know about where in the firewall all those wires are pulled thru, hopefully it is easily visible. and for the wires, I was going to run them all underneath that door sill, plastic piece, that is what i have dont in other cars and never had a problem, as long as I dont get a screw them when I put it back in place.

 

im not sure about where to the hole(s) are in the firewall, but i would check under the steering wheel.
and i would also run the wires from the inside out, cuz it would probably make the job easier. (push the wire thru the hole from the inside, then pull the wire thru the rest of the way from the engine bay)
if best buy or future shop can do it, it cant be that diffilcult...
i would have done it myself, but im not that confident on brand new cars.... older cars are easier to work on

 

When u do run the power wire make sure that you don't run your signal wires next to the power wire or may get some unwanted interferance depending on the type of wires you are using. And you can drill an new hole in the firewall and put in a rubber gasket to protect the wire from the edges of the firewall. Good luck.

 

Without pulling the tin heat shield and firewire foam/padding u go through the passenger side front fender... then fish it down the fender to where the door meets to door access hole and that meets up with passenger kick panel...then run it under the seat belt and door molding to the trunk. Let me know if u need wire codes for the rear Bose for preouts
