  1. 4th Generation Optima (2016 - 2020)
    Greetings all! I have a 2020 Optima fe. It's pretty much basic, but I was thinking if it would be worth the effort of adding a couple speakers. I'm not looking to upgrade the entire system, but it feels like a couple addition speakers would help fill in the sound. Are there decent options...

    Hello all, Just go my 2019 LX optima, its a great car, but the stereo leaves something to be desired, my '17 challenger had a kick ass stereo. Anyone have any suggestions on upgrading the stereo?

    While I find my Infinity speaker system in my 2014 EX nice.. much better than the standard system, I wish the system would be louder. It seems like I have to turn mine up past 30 to be considered loud. Nothing is wrong with my unit (to my knowledge), but I just feel it could louder. Is there...

    Thinking about swapping my speakers in my 16 lx for aftermarket what have you had success with? Did you use deadening? Coax or component? Stock head unit or amped mids and highs? And most importantly did you run a sub as well? I had an amped jbl and Rockford setup in my challenger and honestly...
