MA754AM 4-Channel Amplifier - 75W

The marine A754 4-channel amplifier delivers a powerful 75-watt RMS to each of the front and rear speakers in a boat. You can also bridge the amp to 2-channel mode to drive a couple of subs with a 200-watt RMS or 3-channel mode to drive both a pair of full-range speakers and a subwoofer.

Speaker-level inputs allow this amplifier to integrate into almost any system, even one using a marine factory radio. Separate high-pass and low-pass crossovers on the front and rear channels allow users to dial in the perfect roll-off to best suit speaker placement and cabin acoustics.
