There are 2 ways that it can be run. You can remove the backseat and run under the carpet or you can tuck it in the crease of the backseat and run under the door sills to the front. Depends on where you're going to mount it. Wire length really isn't an issue since all JL uses is a regular phone cable from what I can tell/remember. I hope to get some time in the garage this week so I'll try and take some pictures.
