Class-D amplifier design delivers higher efficiency and greater output. 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. Rigid aluminum alloy heat sink is molded for greater dissipation of heat. The amplifiers are available in monoblock, 4-channel, 5-channel, 6-channel and 8-channel configurations.
