R2-500X1

The Rockford Fosgate R2-500X1 from the Prime Series is a powerful and compact Class-D monoblock amplifier designed specifically to drive subwoofers. With up to 500 watts RMS at 2 ohms, it delivers powerful bass reproduction, high efficiency, and numerous adjustment options for optimal integration into your existing car audio system.

Thanks to efficient Class D technology, the amplifier stands out for its low heat generation and compact design. The integrated C.L.E.A.N. technology makes it easy to set the input sensitivity correctly and helps prevent signal distortion. The bass response can be customized using the variable low-pass filter, the infrasonic filter, and the built-in Punch EQ.

The R2-500X1 supports both RCA and high-level input signals, making it suitable for aftermarket radios as well as factory-installed audio systems. An automatic power-on function, RCA signal outputs, and the wired bass remote control provide additional flexibility during installation and operation.
