Hey Fernboy61, I'm new to this and all but I have a 2015 Chrysler 200 Limited with what i think is just the six speaker system. The car came with the 5.0 uConnect but I have since upgraded to the 8.4 uConnect. I really want to upgrade the way the car audio sounds but I have no clue where to start. I had a car audio place install a Line Out converter to have my two 12 inch subs put in. I asked them how to make my car sound better and they said the only way was to upgrade my head unit. I do not want to change my head unit, I would though like to know what you did to your car and how I can go about this confusing process. I don't know if you reply on this forum or if you just email me back. If you email it's coltenlimbach@yahoo.com. Thanks
