Class AB amps: the more traditional car amplifier design, delivering low distortion and high reliability, usually from a larger chassis. AB amps are not very efficient, losing about half their power to heat.

Class D amps: higher efficiency, less heat, and less current draw than AB amps. Modern designs have eliminated the distortion that's been an issue in the past, and their compact size makes them a great choice.

BR (Boosted Rail) amplifiers use a special design that eliminates the built-in power supply, so they can deliver big power from an extremely small chassis.
