The Audison AF M4D car amplifier adds four amplification channels to AF bit processor amplifiers and can be connected to them using the included plug-and-play signal input harness. Its “straight-through” architecture does not include analog preamp functions such as a crossover filter and is intended for use with external processors. D-Class technology provides a frequency response of up to 42 kHz, while pairs of channels can be bridged for greater output power.
