1) Do I need to disconnect the battery? I thought I could just remove the inline fuse to the amp until I was done.

2) Are there wire pass-through holes behind both driver and passenger seats?

3) How do I access said holes behind the seats.

4) Thanks!

 

It's always a good idea to remove the battery cable. It's best to not run the risk of shorting something out (I've arc-welded the tip of a pocket knife to the cab of my truck once - was using it to strip 4ga).

Behind the seats does have holes to pass through to the trunk. It's best to remove the seats and trim (just a few screws) instead of just trying to force the wiring through.

Pull the 4 bolts on the seat. Pull up the door sill (will just pop up). The hooks behind the seats hide the screws that hold those panels on, remove the hooks and then the panel. The side panel has a screw at the bottom and then it pops off. Install is the opposite.
