OK I "have heard" that even though my 2012 RT has no audio system, the wiring to the speaker housings is there as part of the basic wiring harness. Is this true? What I'm hoping to do is to be able to use/wire in an audio player of some kind into the audio wiring if it is already there as part of the basic wiring harness? PS: Would this be more trouble than it's worth? To get a spyder AM/FM radio and speakers installed will cost almost 800 dollars!
