Hi guys, I'm in the process of install a totally new stereo system in my 2006 Navigator and can't find a good spot on the firewall to run some 4 gauge wire into. I prefer to stay on the passenger's side of the vehicle, and there seem to be no existing grommets I can share that have enough room for this wire. I'm not opposed to putting a new hole with my own grommet somewhere, but anything I can get my drill and step bit at if I were to remove the battery seems to have a cluster of electronics and HVAC stuff directly behind it. Any suggestions that don't involve running the wire under the car, nor to the driver's side?? Thanks!!

 

Anyone???????????????????

 

Just find a convenient spot below the cluster of electronics to drill a hole and pop a grommet in it.

 

Thanks for the response Alloro. Sounds feasible, but anywhere that I can find to drill a hole would be low enough on the firewall that I would have to either remove a bunch of stuff from the engine compartment that isn't exactly easy to remove, or remove the dash, in order to have room to get a regular or right-angle drill into so I'm not drilling at an angle.

As much as I don't want to do it, I might be forced to find a path closer to the underside of the car to run this cable through. :|

 

That's okay as long as you weather protect the cable and seal the penetration with caulk.
