BMW i3/i3S with Harman Kardon (HK) | 8-channel DSP sound upgrade

Upgrade amplifier system with subwoofer for BMW i3/i3S with factory-installed Harman Kardon sound system. Replacing the factory amplifier significantly increases the sound system's power, dynamic range, and overall sound quality. After the upgrade, all speakers are supplied with ample power by the much more powerful DSP amplifier. We also offer three speaker upgrades to complement this set, which, together with this product, will elevate your BMW to a new level of sound. Installation is easy, even for beginners, thanks to the plug-and-play wiring harness and the pre-programmed amplifier; no further adjustments or routing are required.
