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.
The built in CANbus interface generates an ignition supply, this means installation is plug and play.
Note: Some early Audi TT cars will have CANbus wires at the back of the radio but do not carry the CANbus ignition data.
Fitting instructions are included for the amplifier interface. The amp turn on wire is already wired into the vehicle connectors, the amp turn on wire needs to be connected to the new stereo.
