Mercedes/Porsche Active System AdapterActive system adapters retain the functionality of the amplified factory system. This allows you to connect an aftermarket radio to a system with a factory amplifier while retaining the OEM amplifier and connected speakers by adjusting, matching or converting the signal source's output signals to the OEM amplifier's input signal. Depending on the vehicle and the installed OEM system with amplifier, various functions such as sound or subwoofer settings may be lost. In individual cases, depending on the OEM system and the retrofitted radio, increased noise or turn-on or turn-off noise may occur. Check functionality before final installation.
