Goldhorn has launched a new product – the AB218, a special DSP amplifier made just for new energy vehicles (NEVs). It’s the first DSP amplifier in the world that uses A²B technology, which means it offers better sound with smarter connection. This product is designed to improve your car’s sound system with high quality, easy installation, and full compatibility with modern electric cars.
Pure Digital Signal for Better Sound
AB218 supports A²B digital input, so it can get the original sound signal directly from the car – without passing through the factory amplifier. This helps avoid sound loss caused by too many signal conversions. The result is cleaner, more accurate, and high-quality sound.

Works with ANC and Voice Assistants
Many electric cars come with Active Noise Cancellation (ANC) systems and voice control. Some DSPs can cause problems with these features. But AB218 is different – it can work perfectly without removing the original car microphone, so ANC and voice assistants still work normally. It’s a true plug-and-play upgrade.
High Power Output – Can Replace the Factory Amp
AB218 has 20 powerful output channels:16 channels: 80W/4Ω and 4 channels: 150W/4Ω;2 bridged channels: up to 200W each. With a total power of up to 2200W, AB218 can fully replace the factory amplifier and power even complex sound systems easily.
Great Tuning and Ongoing Software Updates
AB218 comes with pre-tuned sound settings made by professional audio engineers. You can enjoy great sound right away. It also supports OTA (Over-the-Air) updates, so the system can keep getting better over time – without changing anything in your car.
Compatible with Many Electric Vehicles
It is reported that the AB218 has completed compatibility with dozens of mainstream new energy vehicle models. In the future, it will gradually support more new energy vehicles equipped with the A²B protocol through DIP switch settings and remote firmware upgrades. If you want better sound in your new energy vehicle, AB218 is a great choice.+
