2011 Chevy HHR Stereo Wiring

Looking for the stock wires for a 2011 CHEVY HHR. Want to upgrade or add a Kenwood aftermarket amp and a JL sub. Is there already a pre existing remote turn on wire I can tap into for the aftermarket Kenwood amp what color is it / where can I find it ???? All help is appriciated !!

I believe 2006 through 2011 were the same, but very before making any connections.
