Goldhorn A²B Plug-and-Play Harness for Electric Vehicle Car Audio Sound Systems | BYD Seal / BYD Sealion/Tang/Han (Dynaudio) | 1.5 Metres

What does it do?

The harness provides the vehicle-specific connection between the BYD factory A²B Automotive Audio Bus and a compatible Goldhorn native-A²B DSP amplifier, particularly the Goldhorn AB218. This lets the amplifier access the vehicle’s digital audio stream before it is converted and processed through the original factory amplifier. When used as part of the complete Goldhorn A²B integration system, it is designed to support:

• Direct digital A²B signal access
• Plug-and-play connection to the factory wiring
• Retention of factory warning chimes
• Retention of active noise cancellation
• Retention of factory controls and microphone-related functions
• Compatibility with vehicle over-the-air software updates
• Installation without a separate A²B-to-optical converter

*These are complete-system capabilities. The harness itself is the physical vehicle interface and does not provide DSP processing or amplification on its own.

Compatible Models: 

• BYD Seal
• BYD Sealion
• BYD Tang
• BYD Han
