Rockford Fosgate M750-1D Monoblock Class-D 750 Watt Marine Amplifier

Big power, small chassis

Rockford Fosgate's compact marine amplifiers provide high-efficiency Class-D power for your boat's marine audio system. They meet tough UV and Salt-Fog protection standards, so you can install them with confidence in your pleasure craft, whether you're blasting across inland waterways, or cruising out to your favorite salt-water fishing grounds.

All the inputs you need

Up to 750 watts

The M750-D1 mono amp delivers the power you need to belt out the bass, sending 400 watts continuous power to a 4-ohm load, 600 watts to 2 ohms, and 750 watts to a 1-ohm setup. It's ideal for multi-sub applications. A variable low-frequency filter adjusts the amp's output to your system, and you can use Punch EQ to add a little low-end bump when you need it. You can install this compact amp in a small storage locker or another tight spot.

Our Moto-marine amplifiers have not only the capabilities you expect a Rockford Fosgate amp to have, but we have designed them to stand up to the environmental conditions you are likely to subject them to. With corrosion-resistant stainless steel hardware and two-part epoxy coated circuit boards, these units are designed with you in mind. Whether on the lake, on the road or in the backwoods these amplifiers are ready for an adventure.

Dust - We make sure that displays and motor structures are sealed up tight so they look as clear as possible and perform day in and day out no matter how many times you hit the trails. 
UV Inhibitor Materials - Centrex and ASA plastic materials are used for their UV radiation resistance and components are tested in accordance with ASTM D4329 testing and certification procedures. 
Corrosion Protection (Electronics) – Two-part epoxy coated PCB boards prevent corrosion of critical components due to exposure in moisture-rich environments. 
Stainless Hardware – Stainless hardware is used due to its natural resistance to corrosion and rusting. This ensures that electrical connections will not degrade over time due to exposure to the elements.
