Rockford Fosgate R2-250X1 Prime 250W Mono Amplifier | Class-D Power

The Rockford Fosgate R2-250X1 Prime is a compact, full‑range mono amplifier designed to bring powerful, controlled bass to your subwoofer setup. Measuring 1.9" x 6.8" x 8.1", this unit fits neatly under seats or behind panels while delivering serious output: 250 Watts RMS at 2 Ω and 150 Watts RMS at 4 Ω. Its Class-D design emphasizes efficiency, allowing you to enjoy extended listening without overburdening the vehicle’s electrical system.

Supply that delivers more power as voltage rises, and the integrated Punch EQ for bass enhancement make it easier to tailor the sound to your vehicle and music style. A variable infrasonic filter and remote level control further empower you to fine‑tune the bass response to taste, whether you’re cruising city streets or blasting highway tunes.
