Mono Subwoofer Amps Information

Mono Subwoofer Amplifiers

Mono amplifiers are single channel amps, but they can be used to power more than one subwoofer. Mono amps typically produce more power than multi-channel amps, which makes them ideal for powering subwoofers. Class D mono amps are the most efficient of all amplifier designs because they draw less current and as a result generate less heat in comparison to the classic mono amplifier design.

A mono amplifier puts out only one channel of sound, as opposed to a stereo amp that puts out two channels of sound. A mono amp is generally used for extremely low frequencies, such as bass, that are channeled into a single subwoofer. It doesn't matter that both stereo channels are combined for these low bass frequencies because you couldn't tell which channel the sounds are coming from anyway because you feel the sound pressure more than hear the sound.
