  1. 3rd Generation Optima (2011 - 2015)
    I've been rattling my brain trying to find a good grounding point for my amp in my 2013 Kia Optima EX. I had a spot that has apparently gone bad. My next idea was a self tapping screw somewhere along the side of the trunk but I came here to ask about it before going into those kinds of measures...

    Hi there, Kia Optima Phev 2018. A few days ago when I turned on the vehicle the Harmon Kardon sound system did not play any sounds what so ever. The Kia dealer in Denmark has spent two hours trying to diagnose the problem, but no luck so far. Everything on the multifunction display is working...

  4. 3rd Generation Optima (2011 - 2015)
    So my 2013 Optima EX gdi has had an electrical issue since I bought it used, it has a draw in the battery so if I don’t start it every day it won’t start but that’s another problem I’m trying to figure out, right now I’m dealing with a audio issue. After my car wouldn’t start I asked someone to...

    Hi. I have KIA Optima 2015, buttons on steering for audio are completely dead while i am driving straight. As soon as I turn the steering either way they start working. What could be the issue possibly?
  6. 3rd Generation Optima (2011 - 2015)
    Hello, I have an Optima 2013 optima turbo with a Infinity sound system. I’m looking to upgrade all the possible speakers to have a better louder and better sound quality. For some reason i just realized that my door speakers are base only, while the three on the dashboard are voice. Also...
  7. 4th Generation Optima (2016 - 2020)
    I'm looking for a list of recommended equipment and some basic install tips for dummies. I have some older experience doing speakers/amps/subs/wiring all that but newer cars are newer beasts. What are the pros/cons/necessitees in order to install a sub/amp kit with the factory radio. Thanks...

    So I’m not very tech savvy in the car audio department so I apologize if I say anything wrong. Recently my car audio system (Kia optima 2015 SXL with infinity sound system) started to get quieter and has gotten worse in the last month. I bought the car it was fine about a year ago. 20 on the...

    I recently bought a 2012 optima hybrid from a dealer and I'd like to know if my car has an infinity sound system so I can know what to get when I upgrade the stereo; how can I tell if it has an infinity sound system? Thanks!

    I cannot seem to find this information anywhere... From what I have found so far, it seems the infinity stereo systems of the SX and SXL models use 4 ohm speakers. I have the 2013 LX, with the base stereo, and the drivers of the speakers were miniscule. I am assuming they were 2 ohm, or maybe...

    This is clearly Trivial Vs a blown engine but I'm wondering Why (since Nav v13) my audio drops from 10 to (ie) 2 in R and comes back in D. The ONLY techie fact I know is that the Bkup Camera is engaged in R and I'm lost from there. The Murphy's Law factor I've considered is that via a v13...

    Does anyone know what the speaker wire colors are? When you replaced your speakers, did you reuse the plastic speaker holder/adapter or did you just screw the speaker back to the plastic? How did you run your speaker wires? Any help and pictures would appreciate. I've researched and found...

    I have a 2011 Kia Optima SX. For quite some time my Sirius xm was stuck on acquiring signal. I didn’t have any audio for Sirius yet AM/fM worked fine. I also wasn’t able to tune to any channels. I did have an active subscription but since I had this issue starting in May I decided to deactivate...

    Hello all I am in the process of the following as I have been wanting to put a system in this car since day one. That being said the staging in this car is phenomenal from factory. I am pretty big on SQ and even in my base model with he speaker placement it is very good. Anyways here is what I...

    My 2017 Hybrid EX came with the Harmon Kardon sound system, and Sirius/XM radio sounds amazing. But the audio from my iPhone seems kind of flat in comparison. Do I need higher bit-rate MP3s? Is it because the iPhone isn't playing surround sound audio? Is there any way to get better audio out of...

    I've always carried my music with me, since I prefer not to use music streaming. I've kept it on a PocketPC until recently, when that device died, and I transferred it all to my old phone, a Galaxy S5 running a stripped down OS. Currently, I am using the S5 as a media center, with an augmented...

    Hello!! My name is Alison and I have owned a 2013, 2015, and now lease a brand new 2019 Optima SXL and so far, with a few minor complaints this year, have loved everything about all of them. I live in eastern Long Island, NY. I have bragged about my car since 2013. LOL I fell in love. :rolleyes...

    Usually I install my own car audio (pre 2000's) and have never had any problems. I have researched my car audio, bought all the necessary pieces/controllers, and ran all the wires (leaving extra to get to their exact locations), and wire loomed them so everything looks pro quality like I never...

    Hey all.. I am the new owner of a 2015 Optima EX with standard audio (no nav, no premium sound). System is OK, nothing special. As with every other car I have owned, I plan on replacing pretty much every component of the audio system. I like to have good sound and good clarity with a bit of...

    OK everyone, I thought I'd try here as my Google searches didn't reveal much useful. I have a 2017 Optima PHEV (I don't think the PHEV part matters for this purpose). So let's say I am listening to music from my phone via bluetooth. Done driving, turn the car off. Next time I get in the car...
