How did your install go? I'm looking to do something similar - thinking about locating the rear unit where the audio amps are, and putting small 12V gel-cel battery back there as well.I can't seem to find any easy way to run either power from the battery to the main unit in the trunk, or the connection wire from the main unit up to the face plate.
Any ideas how to do this safely, without tearing the interior up, and without leaving exposed wires running along the floor boards? :cheesy:
