I'm installing an aftermarket radio today and can't find a color code chart that matches my Xfire's wires! The colors are kinda faded and are different from what I'm finding on the web. Can anyone help me out with what goes to what and +/- speaker phasing in the picture below??????? I didn't think it would take an electrical engineering degree for such a simple task! LoL Thanks (Or maybe I'm just dumber than dirt!)
