Personally, I feel that Kickers suck. Their subwoofers are just ok, but their 6x9s and 3.5s are no where near as good as some other similarly priced brands and models. I happen to love JBL who is owned by Karman, which is owned by Harman-Kardon which is owned by Samsung! The amp in your vehicle is a Harman.
I have a 2013 1500 Sport with the 8 inch screen, no Alpine. I used to have a 2012 SLT. Both trucks had those ****** Mopar Mexico paper speakers all around. I upgraded to the JBL Studio in my 2013. The sound is amazing even with the stock Harman internal amp. One of the reasons why is the JBLs are 3 ohm speakers and the system is 4 ohm, so they are louder. They are cleaner sounding than the mushy Kickers. And especially the 3.5 dash speakers. They now produce trebble and mids, like voice, beautifully. There is no "kit", just go to Amazon and buy 4 JBL 6x9s and 2 3.5" speakers and put them in yourself. It is plug and play with the two dollar Mopar adapters.
And yes there's more! I sold the factory 6x9s on ebay for $20 each. That $80 paid for one set of speakers!
I know how bad the 6x9 Kickers are because I put them in my 2010 Challenger R/T. I installed two Infinity 3.5s in the dash. The Kickers are 4 ohm and as I said before the Infinitys are 3 ohm. What a mis-matched set of loudspeakers. The dash Infinitys are louder than the 4 Kickers.
That is my not so humble experience. Yes, I was an audio engineer in the past so trust me. I would not lead you astray.
