R2-250X1

The Rockford Fosgate R2-250X1 from the Prime R2 Series is a compact and powerful Class-D mono amplifier designed specifically for driving subwoofers. With up to 250 watts RMS at 2 ohms, it delivers reliable bass amplification with high efficiency and a compact design.

Thanks to the built-in C.L.E.A.N. technology, the input sensitivity can be precisely adjusted to prevent distortion. The adjustable low-pass filter, the infrasonic filter, and the built-in Punch EQ bass boost allow for customization to match the subwoofer being used.

The balanced differential inputs reduce noise, while the high-level input function also allows connection to factory-installed car stereos. A solid aluminum heat sink and integrated protection circuits ensure reliable operation.
