Audi BOSE premium quality quadlock to ISO adapter harness with CANbus wires 20-276 CT51-AU04

This interface allows the connection of an aftermarket radio to an Audi car that has a fully amplified audio system with a quadlock connector behind the radio.

It converts the normal speaker level output from the new radio to a pre-amplified level that will work with the original amplifier.

This interface gives very high-quality and clean audio output to give the very best installation.

It also has CAN breakout wires to easily add a CAN bus interface to the install. These interfaces will include items such as our Slimkey interface, which will give a CAN-generated ignition or our steering wheel control interface to allow you to keep the use of the steering wheel control buttons.

Fitting instructions are included for the amplifier interface. The amp turn-on wire is already wired into the vehicle connector; a connection to the new stereo for the amp turn-on wire is needed.
