PM600X4

The Rockford Fosgate PM600X4 is a high-performance 4-channel marine amplifier from the Punch series that delivers powerful and precise audio reproduction thanks to its Class A/B technology. Thanks to its rugged construction, specifically designed for marine use, this amplifier is ideal for boats, watercraft, and high-end audio installations.

With a total output of up to 600 watts RMS, the PM600X4 offers flexible connection options. In addition to standard 4-channel stereo operation, the amplifier can be used in bridged 2-channel mode or in 3-channel mode with speakers and a subwoofer.

The built-in, adjustable high- and low-pass crossover, along with the Punch EQ, allow for custom sound tuning. The innovative C.L.E.A.N. technology makes it easy to set the optimal volume level and helps prevent distortion. Additional RCA outputs allow for easy expansion of the audio system.

Specially coated circuit boards, corrosion-resistant stainless steel components, and a solid aluminum heat sink ensure high resistance to moisture and harsh environmental conditions.
