Even though I still don't have my front components yet (Alpine SPX-17PRO) I was going to just hook everything up and use the JBL speakers for now.
However, I discovered that the existing components are actually bi-amped and since I don't happen to have crossovers sitting around to use, I've decided to put the amplifier/speakers part of this project on hold and just work on the electronics.
The first device I decided to install is the Alpine
NVE-N872 navigation system. Since it is DVD based, it has to be mounted flat. With such a large truck, you wouldn't think finding a flat surface to install it would be difficult - wrong! The bench seat in the back folds almost flat to the floor squashing anything under it and there are ventilation ducts under the front seats. Finally, I just decided if I was careful, I could mount it under the driver's seat.
So, out comes the seat. You gotta love new trucks. The seat bolts release so easily! Three plugs later and here we are:
The brackets are turned outwards and mounted to the "humps" the seat is bolted to. The power cabling runs to the trough in the door sills and the display and signal cables are run to the hump and through the center console.
While I had the seat out, I also ran the majority of cabling that will be required for the electronics in the back (optical, AI-Net, etc).
