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.
In addition to this tuning, poly-fill can be used to fill the subwoofer box. This will help improve the lows and make the subwoofer seem as if it is in a larger enclosure.
