I have an 02 Expy. I want to install a new cd player, amp and sub. What is the easiest way to route cables from behind the deck to the back of the vehicle. I know you can use the door sills, but how do you route from behind the deck to the door sills?

 

Here is what I did:

Remove the kick panels and the door panels. You will see a rubber boot where the factory wiring runs into the door. Pop that out of the hole, and carefully cut a hole just large enough to fit the speaker wire though. Using a straightened wire coat hanger, slip it through the hole cut in the rubber boot, and into the cabin you should see it come out by the pedals. Using tape, secure the end of the speaker wire to the hanger, and than pull the hanger back out. That will feed the wire through the boot. Then feed the wire though the boot in the door, and terminate and connect to the speaker. If you want, you can use silicon caulk to seal around the wire in the rubber boots. Reinstall the kick panels and door panels. Tuck the speaker wire under the carpet, keeping it away from the power and remote wires if you didn’t remove the seats. Feed them up and into the trunk. If the amp will be powering the rear speakers, cut an appropriate length of speaker wire, terminate, and attach to the speakers. Reinstall the seats.


Thats one way to do it. TEK2000 is more of a professional, I'm sure he'll post soon! He will be able to help you more
