i see that the amp is a pioneer amp, but the wiring is not the same as the non nav pioneer. the rear speaker and sub wires are the same, but the fronts and the powers are different. i figured out the front speakers, the 12v, but can't find a 12v switched. i have tested every wire down there, but can't figure out what turns the amp on.

where is a 12v switched?

btw, i went from nav to a dvd flip out, with polk momo 6.5 components and momo coax's, powered by a couple of momo amps, and a nasty 7th order single 12.
