• Direct A²B signal extraction bypasses unnecessary factory amplifier conversion stages
  
• Twenty amplified channels can replace complex multi-channel OEM amplifier systems
  
• Twenty-eight-channel DSP provides extensive control for active and surround audio configurations
  
• Designed to retain active noise cancellation, voice control and factory microphone functionality
  
• Vehicle-specific harnessing allows a reversible installation without cutting the original wiring

• Compatible electric and new-energy vehicles using an A²B communication bus, e.g. select Tank / BYD vehicles
• Premium OEM systems requiring complete factory amplifier replacement
• Multi-way active systems with numerous speaker locations
  
• Vehicle-specific upgrades where ANC and factory functions must be retained
  
• Professional installers requiring high channel count, integrated amplification and detailed DSP control

The AB218’s strongest advantage is its ability to access the vehicle’s native A²B signal while replacing a complex multi-channel factory amplifier. That provides a much cleaner foundation for tuning than converting an already processed analogue signal, while retaining the integration modern EV owners expect.

The Goldhorn AB218 is not a universal amplifier. Compatibility depends on the vehicle’s factory A²B architecture, firmware and the availability of the correct vehicle-specific plug-and-play harness.

Confirm the exact vehicle model, production year, factory audio system and required harness before ordering. Installation and professional DSP tuning are recommended to achieve the intended performance and maintain correct factory-system operation.
