PM1000X1bd

The Rockford Fosgate PM1000X1bd is a powerful 1-channel marine amplifier from the Punch series featuring efficient Class bd technology and an output power of up to 1,000 watts RMS at 1 ohm. Designed specifically for driving subwoofers and high-powered midbass speakers, it impresses with its high power reserves, precise bass reproduction, and a rugged design optimized for marine use.

Thanks to its durable circuit board coating, corrosion-resistant stainless steel components, and solid aluminum heat sink, the amplifier is particularly well-suited for demanding environmental conditions. The integrated C.L.E.A.N. technology facilitates optimal level adjustment and helps detect signal distortion early on.

With a variable low-pass filter, a built-in infrasonic filter, and the adjustable Punch Bass EQ, the PM1000X1bd offers extensive options for customizing bass response. High-level inputs with an automatic power-on function also allow for easy integration into existing audio systems.
