PM300X1

The Rockford Fosgate PM300X1 is a powerful 1-channel marine amplifier from the Punch series with up to 300 watts RMS. Thanks to its full-range technology, this Class A/B amplifier is suitable for powering a subwoofer as well as for driving individual speakers or multiple speakers connected in parallel. Its compact design allows for space-saving installation, while the construction—specifically developed for marine use—provides reliable protection against harsh environmental conditions.

The integrated C.L.E.A.N. technology makes it easy to precisely adjust the input sensitivity and helps prevent signal distortion. With adjustable high- and low-pass filters, Punch Bass EQ, and Punch Treble EQ, the sound can be customized to your liking. Corrosion-resistant stainless steel components, a special protective coating on the circuit boards, and a solid aluminum heat sink make the PM300X1 a versatile solution for high-quality marine and car audio applications.
