PM500X2

The Rockford Fosgate PM500X2 is a powerful 2-channel marine amplifier from the Punch series that impresses with high output power, extensive adjustment options, and a rugged design. Thanks to its Class A/B technology, the amplifier delivers precise and dynamic sound reproduction with up to 500 watts RMS in bridge mode.

Designed specifically for marine applications, this unit features a double-epoxy-coated circuit board, corrosion-resistant stainless steel components, and a solid aluminum heat sink. As a result, the PM500X2 is particularly well-suited for use on boats and in demanding environments.

With built-in C.L.E.A.N. technology, the amplifier can be optimally leveled, while the adjustable high- and low-pass filters and the Punch EQ allow for custom sound tuning. High-level inputs with automatic power-on, RCA loop-through outputs, and the optional PLC2 remote control provide additional flexibility during installation.
