⚠️ IMPORTANT NOTE ON INSTALLATION:

Like many modern VW/Audi electronic modules, this unit has Component Protection. After installation, the amplifier will likely need to be "unlocked" and adapted to your vehicle's VIN by an Audi dealership or a qualified independent specialist with the proper diagnostic tools. Without this step, you may only get sound from one side of the vehicle or have other functional limitations. Please be aware of this requirement before purchasing.
