M2-500X1

The Rockford Fosgate M2-500X1 is a powerful and highly efficient 1-channel marine amplifier from the M2 series, delivering up to 500 watts RMS into 2 ohms. Thanks to innovative Element Ready™ technology, this monoblock amplifier was specifically designed for use in demanding environments and is ideal for high-performance subwoofer systems in boats and other recreational vehicles.

Modern Class D technology enables high output power with low power consumption. The integrated C.L.E.A.N. system facilitates precise adjustment of the input sensitivity and helps detect distortion early on. P.O.W.E.R. technology optimizes power output based on the available supply voltage.

For custom bass tuning, the M2-500X1 features a variable low-pass filter, an adjustable infrasonic filter, and the powerful Punch EQ. The included RLC bass remote control allows you to conveniently adjust the subwoofer level from your preferred listening position.

The rugged aluminum housing with a UV-resistant powder coating, corrosion-resistant connectors, and specially protected electronics ensure high resistance to moisture, dust, and demanding operating conditions.
