Patented circuitry keeps power levels to the output transistors consistent at all times, so you enjoy outstanding fidelity and low distortion. For dead-quiet performance, the M4300 also employs a "differential-balanced inputs" design, which stops noise generated by your boat's electrical system from entering the amplifier.
