How would one go about doing this?? Are the head units any different other than the Mach 1000 having the MACH button instead of audio mute?? Could i keep my stock head unit and just add a toggle switch to turn the 1000 on? Also, how would i go about adding the subs to the back? Are there stock harness plugs already there? Or would i need to totally redo the setup to do this (which means i wouldn't do it) I don't want to go aftermarket. I like stock factory setups and i was pleased with how the mach 1000 sounded in a friends car
