MAIN FEATURES

 

ISO adapter harness for Audi A3, A4, A6 and TT cars with original BOSE amplified audio systems.

 

This harness adapts from the original ISO and Mini ISO connectors at the back of the head unit to standard aftermarket ISO connectors. The harness has a built in high to low level audio adapter to drop the speaker outputs from the new head unit to a low line level signal to work with the original amplifier in the car. The high to low level adapter has 4 dials to individually set the levels of each audio channel to give perfect sound quality.

 

A hardwired ignition supply will need to be connected when using this adapter.

 

The adapter has loose wires for connecting an ignition supply, it also has loose CANbus and power wires to allow easy integration with CANbus ignition and steering control interfaces.

 

Fitting instructions are included. The lead has the amplifier turn on wire already wired into the vehicle connectors, the amp turn on wire needs to be connected to the new stereo.
