| Class-AB amplifier design delivers efficiency with reduced distortion. | Connect up to two speakers per channel at 2 ohms, or bridge two channels at 4 ohms for increased power. | Conformal coated PCBs provide extra protection from the marine elements. | Heat sink provides greater dissipation of heat for enhanced component reliability. | The amplifiers are available in 2-channel and 4-channel configurations. |
CLASS-AB AMPLIFIER TECHNOLOGYThe Class-AB design provides high power output with reduced distortion to the connected speakers/subwoofers for an enhanced level of audio performance. |
ENHANCED SYSTEM PERFORMANCEThe AM Series amplifiers feature built-in variable bass boost, a subsonic filter and variable low/high pass crossover filters for enhanced performance and system protection. |
