4. Setup and Installation

This adapter cable facilitates the connection of an aftermarket car stereo to your Audi's original Bose amplified sound system. The adapter uses the amplified output from your new car stereo.

Installation Steps:

  1. Disconnect Battery: Before starting, disconnect the negative terminal of your vehicle's battery.
  2. Remove Original Stereo: Carefully remove your vehicle's original car stereo unit. Refer to your vehicle's service manual for specific instructions on removing the head unit.
  3. Identify Connections: Locate the original wiring harness connected to the factory stereo. Identify the power, ground, speaker, and amplifier control wires.
  4. Connect Adapter to Aftermarket Stereo: Connect the appropriate end of the Phonocar 04130 adapter cable to the wiring harness of your new aftermarket car stereo. Ensure that the speaker outputs from your new stereo are connected to the input side of the Phonocar adapter.
  5. Connect Adapter to Vehicle Harness: Connect the other end of the Phonocar 04130 adapter to the vehicle's original wiring harness that previously connected to the factory stereo. This adapter will route the amplified signal from your new stereo to the Bose amplifier.
  6. Secure Connections: Double-check all connections to ensure they are firm and correctly matched. Use electrical tape or heat shrink tubing to insulate any exposed wires.
  7. Test System: Before fully reassembling the dashboard, reconnect the vehicle's battery. Turn on the aftermarket stereo and test all audio functions, including front and rear speakers, balance, and fade.
  8. Reassemble Dashboard: Once confirmed that the system is working correctly, carefully reassemble the dashboard and secure the new car stereo in place.

Note: This adapter is designed to work with car stereos that have an amplified output. It converts these signals for proper integration with the Audi Bose system.

5. Operating Instructions

Once the Phonocar 04130 interface is correctly installed, the operation of your car's audio system will primarily be controlled by your new aftermarket car stereo. The interface acts as a bridge, allowing the aftermarket stereo's audio output to be processed by the vehicle's original Bose amplifier.

  • Power On/Off: The Bose amplifier will power on and off automatically with your aftermarket stereo.
  • Volume Control: Adjust the volume directly from your aftermarket stereo.
  • Audio Settings: Use the audio settings (bass, treble, balance, fade) on your aftermarket stereo. The Bose amplifier will process these signals.
  • Source Selection: Select your desired audio source (radio, CD, USB, Bluetooth, etc.) directly from your aftermarket stereo.

No additional controls or adjustments are typically required for the Phonocar 04130 interface itself after installation.

6. Maintenance

The Phonocar 04130 Hi-Fi System Interface is designed for long-term, maintenance-free operation once installed correctly. No regular user maintenance is required.

  • Cleaning: If the adapter needs cleaning before installation, use a dry, soft cloth. Do not use liquid cleaners or solvents.
  • Inspection: Periodically, if you experience audio issues, you may want to inspect the connections to ensure they remain secure and free from corrosion. This typically requires partial removal of the car stereo.
  • Environmental Conditions: Ensure the adapter is installed in a dry environment, protected from direct sunlight and extreme temperatures, which are typically found behind the dashboard.
