Plug&Play harness for Booster HK BMW from 2021
AFBMW BOOSTER 01 is the dedicated Plug & Play cable designed to integrate Audison Forza amplifiers with BMW vehicles equipped with the 688 Harman/Kardon OEM sound system. This system features a dedicated “booster” amplifier that powers the underseat woofers only. AFBMW BOOSTER 01 enables seamless connection between the OEM booster and Audison electronics, without altering the original wiring or affecting system integrity. Important Compatibility Notes Not compatible with vehicles featuring: • Door woofers and a trunk subwoofer (e.g., BMW i4 G26) • Four underseat woofers (e.g., BMW iX) • The OEM booster remains installed and connected to the vehicle network • ART (Automatic Remote Turn-on) is not active on woofer channels, but functions on all other channels of the RAM module
