Why OSCA Backs This Product

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.

Installation / Technical Notes

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.

Unleash the Full Power of A²B

The car already feels like the future. Now the sound does too. The Goldhorn AB218 turns every journey into something cinematic, surrounding you with scale, emotion and impact that the factory system never revealed. Familiar songs feel new again, quiet details step forward, and every drive becomes one you want to keep going.

With native A²B signal extraction, 28-channel DSP processing and 20 channels of integrated power delivering up to 2200W, the AB218 transforms complex EV audio systems into something faster, cleaner, louder and dramatically more precise. Factory ANC, microphones and vehicle functions remain intact while the original amplifier is left behind. This is not a minor improvement. This is a total system takeover.
