M5-1500X5

The Rockford Fosgate M5-1500X5 is a powerful and compact 5-channel marine amplifier from the M5 series, designed specifically for demanding audio installations in boats, marine vehicles, and UTVs. With its rugged Element Ready™ construction and IPX6 rating, it is ideally suited for use in harsh environments.

The innovative Class AD technology in the four speaker channels and the efficient Class BD technology in the subwoofer channel enable high output power with reduced power consumption. Thanks to Constant Power technology, the amplifier delivers reliable performance even with varying speaker impedances.

The built-in C.L.E.A.N. system makes it easy to precisely adjust input and output levels and uses LED indicators to warn of signal distortion. Adjustable high- and low-pass filters, an infrasonic filter, and the Punch EQ tone control allow for customization of the sound system.

The built-in high-level inputs with automatic power-on functionality also allow connection to factory-installed radio systems. In addition, the amplifier offers a convenient preset mode for compatible Rockford Fosgate UTV audio systems.
