Working on it, I know that the back of the headunit has pins for a 'AUX' output.. which as I understand it is for a subwoofer output.
Some have said that this output is MUTED on the Shaker 500 though. and only works on the shaker 1000.
I dont know if thats accurate and its what I'm looking to find out.
Also, I know that the Shaker 500 from 05-09 models had an output that allowed for a mono sub amp from saleen to be completely plug and play.
If that line exists somewhere, especially in the 2010+ models, theres GOT to be a way to tap that signal for an aftermarket amp.
Anyone else have any information on this please help
