P1000X1bd

The Rockford Fosgate P1000X1bd is a powerful 1-channel mono amplifier from the Punch series, designed specifically to drive high-power subwoofers. Thanks to efficient Class bd technology, the amplifier delivers up to 1,000 watts RMS into 1 ohm and impresses with its high power reserves, precise bass reproduction, and compact dimensions.

The built-in C.L.E.A.N. technology allows for precise adjustment of input and output levels via LED-based clipping indicators. The adjustable Punch EQ with up to 18 dB of bass boost at 45 Hz, the built-in low-pass filter, and the 28-Hz infrasonic filter allow for customization to match the connected subwoofer system.

High-level inputs with an automatic power-on function simplify integration into existing vehicle systems. A solid aluminum heat sink, comprehensive protection circuits, and the option to connect an optional PLC2 remote control round out the features.
