Built-in ActivationAudi e-tron GT — Subwoofer Menu Activation (MIB3)
In a silent EV grand tourer, every Hz counts — this activation gives you the hidden Subwoofer slider to finally dial it in.
What You Get
Audi e-tron GT trims with the Audi Sound System (PR-9VD) ship with only Bass and Treble in the MMI Sound menu. With no combustion noise to mask anything, the subwoofer becomes one of the most audible characters of the entire system — yet the factory leaves you with no way to balance it against the main bass response. This activation switches on the hidden Subwoofer slider through a guided, VIN-specific OEM workflow in RetroLab Pro — no dealer visit, no remote coding, no manual scripts.
How It Changes Behavior
From factorythe e-tron GT MMI exposes only Bass and Treble. The silent EV cabin makes every fluctuation in subwoofer level obvious, but there's no slider anywhere to tame or push the low end independently.
After activationa dedicated Subwoofer slider appears next to Bass in MMI Sound, so you can finally compensate for the GT's silent floor — tight and precise in the city, full and cinematic on long touring drives.
