Elite 750-Watt Marine-Grade Bass Authority

The MTX MA750.1 is a high-performance, 750-watt RMS monoblock amplifier specifically engineered to bring deep, powerful bass to the open water. Built to survive the grueling marine environment, this Class D powerhouse features a conformal-coated circuit board and stainless steel hardware to defend against salt, spray, and moisture. Despite its compact, space-saving design, the MA750.1 delivers "Serious About Sound" performance, making it the ideal choice for boaters who want competition-level output without sacrificing precious storage space.

The amplifier also includes a variable low-pass crossover (50Hz–250Hz) and a dedicated subsonic filter (10Hz–55Hz) to protect your subwoofers from damaging ultra-low frequencies. For total control from the helm, the MA750.1 comes standard with an External Remote Bass Control Knob, putting the full power of your marine audio system right at your fingertips.
