As cars' entertainment and infotainment systems add more features and subsystems, the audio power budgets of the head and trunk units are being pushed to the limit.

In particular, multichannel and multispeaker systems are becoming common in high-end cars. The design challenge for automotive engineers is to maintainor even to improvethe high audio amplification levels and low distortion that customers have been expecting.

A specific instance of the need for higher power is the trend toward high-power, two- or even three-way speaker systems and subwoofers.
