Know before you buy
Yes, this is an all-in-one system that includes the 10-inch subwoofer and a matched R1 550.2 marine amplifier. Because the components are pre-matched, you do not need to worry about calculating power compatibility between the sub and the amp.
No, the system is not rated as waterproof. While it is built with marine-grade materials to resist salt, moisture, and UV exposure, it should be installed in a location protected from direct water submersion or heavy spray.
The RMA 10 subwoofer requires a mounting depth of 5.08 inches. Ensure your chosen enclosure or mounting location provides enough clearance behind the speaker for the motor structure.
The R1 550.2 is a 2-channel amplifier. While it is optimized for this subwoofer, it can be bridged to provide 550W of power to the sub, or used in its 2-channel configuration to power other marine speakers if your setup requires it.
The RMA 10 features a versatile design that works well in a variety of enclosure types. You should choose an enclosure volume that aligns with your specific bass output preferences and available space on your boat.
