Whats the story on the different amplifier “classes”?
An amplifier’s circuit design determines its class of operation. Class A amplifiers are desirable for the high quality of their sound, but the design is not particularly suited to car applications because of inefficiency and high heat production. Car amplifiers that boast Class A design are usually a Class A/Class AB hybrids. The Class AB design is most commonly used for car amplifiers because it combines reasonable efficiency, low distortion, and reliability.
