BMW F3x Harman Kardon (688)

Retrofitting the Harman Kardon (674/688) sound system into a BMW significantly enhances the in-car audio experience, offering richer, more immersive sound quality compared to the stock system.

The upgrade includes high performance speakers, a powerful amplifier, and refined acoustic tuning tailored to the F20/F30’s interior, resulting in clearer highs, deeper bass, and better overall sound balance.

This not only improves music playback but also elevates the ambiance during drives. Additionally, the retrofit can increase the vehicle’s resale value and appeal to audiophiles or premium car buyers seeking a luxury audio experience.

This is on our supply, fit, and code package with a 6 month warranty.
