Wiring diagram for 05 h2 nav radio?

[tonybud]

Im looking to hook up a couple of JL audio amps and replace the bose speakers and amp. Does anyone have a wiring diagram of the back of the nav stereo showing the color codes of what each wire is and where it goes? Would like to hook up a couple in line converters for the 2 amps. My h2 is an 05 w/ xm and onstar.
Any suggestions on which in-line converters should be used????
Thanks!
