I wanted a USB port in the back seat area for the wife on long trips and when i use the Gopro camera on the back. so i added a USB port inside the rear speaker pod today. dont know if this has been done before or not, if not, here is what i did. I had her sit in the back seat and see where she could reach and this seamed to be the best spot for her.
I got this from Texas Cycle Chrome. i think its made for the front, but with some modification, it works where ever.
I had to cut one web of the upright with a die grinder to get it to fit without hitting the back of the speaker. then i marked it and cut a hole with a 1" spade bit.
in this pic you can see where i had to cut away one of the webs.
then splice in some two wire connectors and make a wire harness long enough to plug into the 12v in the truck under the trunk lid liner.
used an o-ring on the inside to keep it in place and i put some silicone around it after it was in for final install (not shown)
wire harness with disconnect installed and ran into the trunk.
you can see the wire harness and USB port through the speaker hole in this pic.
put it all back together and this is the finished product.
then i took my tape measures for a ride since they did such a fine job this week.
