A2B Bus
A2B (Automotive Audio Bus) is a digital audio system used in modern vehicles to deliver high-quality sound and entertainment features. Think of it as a special way to connect various audio parts in a car, like speakers, microphones, and entertainment systems, using less wiring than traditional methods. Car manufacturers like this technology because it saves space, reduces costs, and makes it easier to add premium audio features to vehicles. It's similar to how a USB cable can connect multiple devices to a computer, but specifically designed for car audio systems.
