1 � Rear right loudspeaker, positive
2 � Front right loudspeaker, positive
3 � Front left loudspeaker, positive
4 � Rear left loudspeaker, positive

Note! When used with a sound amplifier, the same pin assignments are used as line-in for the sound amplifier. To achieve this, the radio unit is programmed from �output stage power 26 dB� to �output stage line-out 12 dB� in the factory. Details on how to perform this can be found in Volkswagen RNS 510 coding when installing with a factory amplifier.
