I would like to run an xm antenna wire from under hood into passenger compartment.
What might be the best route?

 

That's easy if by "under hood" you mean the front hood. Behind the fuse box area is the main wire harness intro into the interior. It's a tough, tight area to work through however there is no alteration to the vehicle through this pathway; a must in my book.

 

That's exactly what I was looking for. Thanks for the help.

 

I just ran a 6 gauge power wire from the battery to my amp under the passenger seat yesterday. I punched a hole through the grommet under the glove box. I used a clothes hanger taped to the wire and punched a hole through. It came out in front of pollen filter fan. You must start from the inside.

 

I ran 4 gauge wire for my amp from under the driver side essentially replacing the factory wire used for the CD changer. You can do either way, I think I pushed the wire in from the frunk.

 

another route, if you follow the frunk cd changer wire, it enters the cockpit in the driver's foot well by way of a rubber grommet. just use the same hole and rubber grommet. fairly easy to get to from frunk and inside driver's foot well.

 

+1 ...this is true. However, providing the CD Changer cable is present (as is on mine) the grommet space would be hard pressed to co-mingle an antenna coax cable in addition. Otherwise.. its an easy straight shot solution.
