The PRIME R250X1 is a mono amplifier featuring a compact chassis capable of producing 250 Watts of pure Rockford Fosgate power into 2-Ohms. The frequency response of the R250X1 allows it to be used exclusively with subwoofers.

The PRIME R250X1 amplifier is great mono amplifier in a compact chassis and respectable power output in any sound system. The R250X1 mono output design also makes it great for running a pair of 8" or 10" 4-ohm SVC subwoofers wired in parallel. The included Remote Punch Level Control corrects for any acoustic anomalies in the automobile environment, making certain that bass notes sound deep and rich.
