⚙️ Features & Benefits

Genuine Bose Part: Restores the high-fidelity surround sound experience as tuned by Audi engineers.
High Efficiency: Digital processing minimizes heat and maximizes power delivery to the door and sub speakers.
Latest Revision: The "P" suffix represents one of the final, most reliable iterations of this hardware.

🔩 Installation Notes

Located in the left side of the trunk behind the utility storage panel.
Component Protection: This unit may require "un-pairing" at an Audi dealership or a specialist using ODIS/VAS to remove Component Protection, which ensures all speakers function (without it, the unit may only play from one speaker).
Prevention: If your original unit failed due to water, check the rear window washer hose for leaks or the sunroof drains before installing this unit.
