Rockford Fosgate R2-500X4 Prime 500W 4-Channel Amplifier

Primed for Performance, the R2-500X4 is a 500 watt, full-range Class-D amplifier capable of operating at 4Ω or 2Ω stereo and 4Ω bridged/mono. This amplifier is extremely efficient because of its Class-D technology which reduces demand on the vehicles electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. supply that generates more power as voltage increases.

Key Features

  • Auto-Sense bypass switch for vehicles with RAP (Retained Accessory Power)
  • Balanced Differential Inputs with RCA Pass Through Outputs
  • Features C.L.E.A.N. Set-up
  • CEA-2006 Compliant & CE Compliant
  • Short Circuit & Over Current Protection
  • Fully Adjustable 12 dB/octave High and Low pass Butterworth Crossovers
  • Front and Rear Variable Input Gain adjustment level

Features

  • P.O.W.E.R.
    Power supply circuit design that allows the amplifier to increase output power as voltage increases.
  • CTA-2006 Compliant
    Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
  • Class-D
    High efficiency amplifier design that reduces current consumption from the charging system.
  • CE Compliant
    This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
  • Balanced Differential Inputs
    Differential inputs eliminate noise picked up by signal cables.
  • NOMAD
    NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
  • C.L.E.A.N. Set-Up
    C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
  • MEHSA 4 (Maximum Efficiency Heat Sink Application)
    MEHSA4 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

Frequently Asked Questions

  • This amplifier delivers 75 watts RMS per channel at 4 ohms and increases up to 125 watts RMS per channel at 2 ohms. It can also be bridged to provide a higher power output, making it versatile for various speaker configurations.
  • The amplifier is equipped with NOMAD protection which safeguards against shorted speaker wires and dangerously low speaker impedances. Additionally, it features rollback protection to prevent damage from electrical issues and ensures long-lasting reliability.
  • Utilizing Class-D technology, the amplifier offers high efficiency that reduces current draw from the vehicle's electrical system. It includes a cast aluminum heat sink and MEHSA 4 (Maximum Efficiency Heat Sink Application) to lower MOSFET temperatures, decrease distortion, and enhance durability.
  • The frequency response spans a full range of 20Hz to 20kHz. It includes adjustable front and rear low-pass and high-pass crossovers ranging from 50 Hz to 250 Hz with a 12dB/Octave Butterworth slope, allowing precise tuning of audio output to match speaker capabilities.
  • It supports both low-level inputs with a sensitivity range from 150 mV to 4 V and high-level inputs ranging from 450 mV to 12 V. There is also a 2/4 channel input selection switch to accommodate different source setups efficiently.
