These basic types are further broken down into more than a dozen lettered classes.
They use internal circuitry designed to always have current passing through the outputtransistors.
The biggest issue when it comes to class A amps in car stereo applications is size.
Class B Car Amplifiers
Unlike class A amps, class B power amplifiers are switched.
Class AB Car Amplifiers
These amps are a hybrid of the traditional A and B amplifier classes.
That results in greater efficiency than pure class A amps without as much distortion as class B amps.
This creates a switched, or pulsed, output signal that’s mapped to the analog input signal.
