So...I'm installing a sub amp in my new 2012 and for the life of me I can't get a single wire on the rear of the radio to meter out at +12 besides the constant (yellow/red). Any ideas which one would be the kick on wire and why the hell I can't get it to meter out?? I've never seen this before.
I found a wiring diagram that says it's on the 'can bus'. My radio is the stock radio with unconnected and satellite only. Any help is greatly appreciated. Thanks!
