    Engineering Premium Audio in Your Car

    The addition of Harman Kardon premium audio to the Kia line-up marks an extension of a long-lasting partnership between HARMAN and Kia formed in 1998 that has produced some of the industry’s most technologically advanced and best-reviewed audio systems. Harman Kardon engineers worked with Kia during the earliest stages of vehicle development, spending hundreds of hours fine-tuning the audio system specifically for the vehicles cabin size, materials and seating configurations. The result is a system that enhances the driving experience with the true emotional response previously attained with only the finest home-audio equipment, transfixing listeners with 360 degree spatial envelopment and rich, high resolution sound.

  • Music Meets Pure Driving Experience

    Music Meets Pure Driving Experience

    Harman Kardon is distinguished by its comprehensive expertise and the continuous pursuit of an excellent sound experience at home and in the car. The sound systems are highlighted by extraordinary design, premium materials and sophisticated details which ultimately lead to a stunning and unique music adventure.


Harman Kardon®
cutting edge technologies

At Harman Kardon, we strongly believe in first-class quality music reproduction. Music must always preserve its character and nature. Music is a full and rich emotional experience. That attitude determines how we see and use technology. For Harman Kardon, technology has one purpose and one purpose only – to serve the music!

  • HARMAN Clari-Fi™ is a revolutionary technology that brings compressed music back to life. Clari-Fi analyzes digital audio files in real-time and corrects waveform deficiencies based on the existing audio information. Thereby it scales the amount of treatment based on the quality of the individual source signal “rebuilding” much of what was lost in the compression modus. It is easy and convenient as it works at home, on the go, in the car – with Clari-Fi it's simply sounds so much better. Once applied, Clari-Fi works automatically, no need to configure or adjust.

  • HARMAN’s in-house developed QuantumLogic® sound technology creates an unprecedented 7.1-channel surround sound listening experience from any mono, stereo, or multi-channel signal source, hence setting a benchmark in audio signal processing excellence. Revolutionary new audio algorithms, pulling the strings in the background, extract signal streams and impulse responses from the original recording and give audio tracks a natural yet controlled sound quality. It provides a level of subtlety and detail that is as close to the original recording as possible. It is just like being there.

Automotive Reviews

  • 2016 Kia Optima

    “You can opt for a Harman Kardon premium sound system with 590 Watt, 10 speakers, external power amplifier and the technologies ClariFi (improves audio quality) and QuantumLogic Surround (transforms audio signals into 7.1 surround sound).”

  • 2016 Kia Optima EX

    “When it comes to listening quality, a 10-speaker Harman Kardon sound system is available. Included with this is the firm’s Clari-Fi technology, which undoes the damage caused by audio compression, so the MP3s on your iPod or smartphone sound much better. Additionally, this system comes with Harman’s QuantumLogic system, which creates a pretty convincing surround-sound experience.”

  • Kia Optima

    A new-for-2016 feature is a Harman Kardon 630-watt, 14-speaker audio system with Quantum Logic surround sound and Clari-Fi technology. Clari-Fi basically adds in the missing audio information from compressed digital audio, and while it sounds like a black art that could result in horrible artifacts it’s actually extremely effective at making your MP3 and other digital files sound like full-bodied recordings.

  • Kia Optima

    Oh, and the ”QuantumLogic” Harman Kardon stereo really is brilliant, with crisp tones and clear bass coming from even older songs, a product of the brand’s Clari-Fi restoration technology, which revives lost tones from digitally compressed music.

  • Kia Optima

    …and Kia’s first offering of Harman Kardon’s most trick QLS surround sound system. This (also pure magic) super stereo has the ability to extract signals from an original recording and redistribute them for a clearer and more detailed sound; it uses an amazing patented technology that can rebuild audio signals lost in the digital compression process.

  • Kia Sorento - Rudolf Huber, Motorzeitung

    “The new Harman Kardon sound system with a total output of 640 watts produces a great sound.”

  • Kia Optima - Jana Möller, SHOTS Magazin

    “A great praise must be given to the sound system by Harman Kardon, which perfectly suits the interior of the Kia Optima Plug-In Hybrid. Your ears will be spoiled by clear, hard basses or soft string arrangements.”

  • Kia Stinger – Manuel Carrillo III, Carblog

    “In two words: holy crap! The Stinger GT’s Harman Kardon audio stands proud among the five best OEM car audio systems I’ve ever experienced. I’ve been a Bose fan all my life, and I enjoy the Performance Series audio systems they’ve got in the Infiniti Q60 and the all-new QX50, but Kia’s system sounds a class above the Infiniti/Bose systems. What I especially appreciate is how Harman Kardon places low-, mid- and high-frequency speakers in each door. Many automakers with premium audio systems fail to be as comprehensive. Having full-range sound emanating from each door creates a full-bodied, spatial ambiance that fewer speakers and clever digital signal processing can’t match.”

  • Kia Stinger GT – Miles Branman, Digital Trends

    “Harman Kardon is renowned for its quality electronics, but the Stinger’s 720-watt, 12-channel unit is a new benchmark. Few vehicles — at any price point — can match the sound quality, range, and balance of the system.”

  • Kia Stinger GT – Lawrence Ulrich, The Drive

    “…A knockout Harman Kardon audio system with 15 speakers, 720 watts, seat-mounted subwoofers and resonance chambers in the center roof pillars…”

  • Kia Stinger - Helena Stone, The Gadgeteer

    “The built-in 720-watt Harman Kardon premium audio system packs in 15 speakers and it supports hi-res audio files. The audio system inside the Stinger is actually the best sounding speaker system we’ve ever listened to from all of Kia’s vehicles.”

  • Kia Stinger – Dietmar Stanka,

    “This version comes with additional LED headlights, the adaptive chassis, a Brembo brake system, rear seat heating as well as seat ventilation at the front and a brutally cool Harman / Kardon sound system with 15 loudspeakers. The two subwoofers are installed underneath the front seats and use the lower spars as resonances.”

  • Kia Stinger – Peter Withoutfield, Blogrebellen

    “For the sound system in the GT version (of the Kia Stinger), Harman / Kardon has been brought on board, which has a total of 15 loudspeakers installed in the vehicle, as well as some sound-improving software technologies. You can imagine that we demanded a lot from the soundsystem and we were not disappointed. Heavy bass (the bass speakers are installed under the front seats) and a nice overall stereo sound. Top notch!”

  • Kia Stinger – Norbert “Bru” Ambros, Bru’s World

    “In the top model (of the Kia Stinger) with the V6 engine even a Harman Kardon Sound System specially developed for the Stinger is included. Since the engineers of the system were already involved into the planning of the vehicle at an early stage, the loudspeakers and the subwoofers under the seats were perfectly matched to the car. This creates a sound in the interior, which gives you the feeling of being in the middle of the stage. In addition, a Clari-Fi program supports streamed music and improves its weaknesses through an algorithm. I am really going into rhapsodies about it….”

  • Kia Stinger – Eric Bergerolle,

    “The Korean catches up with a comprehensive list of driving aids, a sharp-focus Harman/Kardon audio system and an 8-inch touch screen that does not overpower the conventional air conditioner controls.”
