Description

Product Description:


The factory Harman Kardon Premium Audio System in the Golf 8 GTI/R is supposed to be “premium” sound quality.

However, this was not the case when it was leaving customers disappointed and wanting more.

Customers found themselves upgrading to a Fender subwoofer, changing the coding in the amplifier module to “Beats” claiming it makes it better. Which may do something.

BUT, with this custom amplifier tuning, it will make the Harman Kardon actually worth something!


Tuning was done using a calibrated RTA microphone and a good amount of time spent tweaking to ear based on my custom system. Now obviously this amplifier and the speakers used have lots of limitations so it is not anything compared to a custom audio setup or aftermarket amplifier/system. Tuning was done with an all around sound in mind vs a more focused or specific sound. This is about as good as the system can be without making physical hardware changes.


Features:

  • Improved Bass
  • Louder Output
  • Better highs, mids, and lows
  • Better ability for tuning with on screen controls
  • All factory features such as surround, seating focus, EQ and other controls still work as designed.

 

Works with:

  • 2022-2024 MK8 Golf GTI/R with Harman Kardon Premium Sound
  • 2025+ MK8.5 Golf GTI/R with Harman Kardon Premium Sound

Amazing

The sound quality is way better than stock. I would recommend 100%

Makes the HK enjoyable

It really makes the music more enjoyable without a big investment into changing the speakers. That and adding polyfill in the sub for a few dollars makes the songs sound clear, punchy and vibrant, as opposed to muted and muffled vocals and instruments before.

HK Sound improvement.

Seriously, what a night and day difference. Before felt like I needed the volume to be above 50-60% before I’d be able to get any “drive” out of my speakers, and even then, it would sound thin and weak. After the coding change, even at 25% volume, the sound is so much clearer with some punch to it.
