I have a 2012 sport 2 door. I know thats my first problem. My second problem is my sound bar. I would love to upgrade to one from a 2018 but im not sure if any one has done this. I searched through the forums and either missed it or it doesnt exist. My sound bar currently only has two speakers and due to the fact im a 2 door i have no sub and no room for one. I know the 2018 jeeps had a tweeter sub mix in ther sound bar and was wondering if any one else has upgraded and if its as easy and plug and play or if i need to modify my harness or even go as far replacing my head unit and amp? Any suggestions help. And yes polyfil was added, still sound quality is very lacking. And no im not the type that wants to rattle doors. I just want a bit more substance to the sound. Thanks all.
