Class AB and 4-Channel Car Amplifiers

Increase efficiency and reduce distortion with a class AB amp or 4-channel amps from Drive-In Autosound. Class AB amplifiers combine class A and class B features to attain an amplifier with more efficiency than class A but less distortion than class B. Eliminate crossover distortion while achieving higher efficiency, frequency response and volume, especially at high and mid frequencies. You can connect component speakers, full-range speakers and subwoofers to experience full immersion in your music or shows.
