I went from a 2010 to a 2016. I started by determining what options I absolutely wanted (in your case the sound system and 4x4) and then I determined what I was willing to pay after researching what other people paid. Then I went online and built a Jeep that had everything I wanted and that was within my pre-determained price range. Then I contacted my salesman and told him exactly what I wanted and what I felt was a fair price and we emailed back and forth for a week and eventually made the deal over the phone. Mine was a factory order and I got it cheaper than what I was expecting to pay. Completely happy with the experience and I absolutely love my Jeep.
