Rockford Fosgate Prime R2-250X1 250 Watt Monoblock Amplifier

The Rockford Fosgate Prime R2-250X1 is a 250W monoblock amplifier built for car-audio enthusiasts seeking Rockford Fosgate reliability at an economical price. This 1-channel Class-D amp powers a dedicated sub or bass channel in factory or aftermarket systems with flexible inputs and precise tone-shaping tools.

• 1 Channel / 250 Watts x 1 @ 2Ω (150W x 1 @ 4Ω): Delivers substantial continuous power into both 4Ω and 2Ω loads, enabling strong bass without excessive heat or size.
• Dynamic Power: 209 Watts x 1 @ 4Ω and 328 Watts x 1 @ 2Ω peak capability for short-term demand peaks.
• Class-D Topology: Efficient operation reduces heat and enables compact form factors suitable for tight installs.
• RLC Remote Level Control: Includes a remote to adjust bass level from the dash, simplifying on-road tailoring without reaching behind the amplifier.
• High Level Input Capable / Balanced Differential Inputs with RCA Pass Through Outputs: Lets you connect from factory radios or aftermarket sources while feeding downstream processors or amps.
• 12 dB/Octave Butterworth Crossovers (Continuously Variable): Precisely tailor low-pass and high-pass filters to fit your sub or bass path and system integration.
• Infrasonic Filter: 15 Hz – 40 Hz ensures ultra-low frequencies don’t overburden the enclosure or wash out dynamics.
• Top Mounted Control Panel: Easy access for setup and tuning in tight under-seat or trunk installations.
• Protection & Stability: Short Circuit & Over Current Protection with Rollback Protection safeguard system and wiring.
• CEA-2006 Compliant & CE Compliant: Verified standards compliance for performance expectations and safety.
• Cast Aluminum Heat Sink / Convection Cooling: Robust thermal design helps maintain consistent output during music performance.
• 0 to +18 dB @ 45 Hz Tone Controls: Adds or trims bass presence to match your enclosure and subwoofer.
• Input Sensitivity: Low-Level 150 mV – 4 V; High-Level 450 mV – 12 V for flexible integration with various source signals.
• Frequency Response: 20 Hz – 250 Hz, tuned for bass-focused applications.
• Power Input & Electrical: 4 AWG power input with a recommended 50 A fuse; operates from 9–16 VDC typical car electrical systems.
• Not Bridgeable: Designed as a single-channel power stage; suitable for dedicated sub/bass paths rather than bridged configurations.
• Dimensions: 1.9" (H) x 6.8" (W) x 8.1" (D) for flexible under-seat or compact trunk mounting.

Benefits: In a typical car build, the R2-250X1 serves as the main bass amplifier for a dedicated sub or as the bass channel in a multi-amp setup. Its Class-D efficiency keeps heat and wiring complexity manageable, while high- and low-level inputs ease integration with factory or aftermarket head units. The included RLC remote lets you dial in bass levels from the dash, and the infrasonic filter plus Butterworth crossovers provide precise bass shaping to minimize cabin rumble and bass masking. Protection features and robust thermal design support reliable, long-term performance in daily driving and peak music duties.
