In-vehicle sound systems can be quite complex with multiple speakers, including sub-woofers, spread around the vehicle’s interior to enhance the driving experience with high-end audio, that can satisfy the most demanding music enthusiast.

Traditionally used for playing music and the radio, today's vehicle audio systems include car telematics, diagnostics and in-vehicle services; eCall and hands-free calling; and navigation and telecommunication services.

To help manufacturers to design scalable, high-quality and high-performance sound systems we have an extensive portfolio of automotive-grade audio amplifiers including AB, SB (high-efficiency), SB-I and Class D with analog or digital inputs for any speaker load value, output power and operating voltage.
