Give your speakers the power they deserve

Rockford Fosgate's Prime Series R2-500X4 amplifier can power four speakers with 75 watts RMS each, so you'll hear your music loud and clear over the noises of the wind and road. You could also use this amp in bridged, 2-channel mode to power a couple of subwoofers with 250 watts RMS each. High- and low-pass filters help you get maximum performance from the speakers in your vehicle.

The Prime Series was developed for car audio fanatics that want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “underrated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of Prime Series amplifiers are also designed to be easy to setup and configure, making them perfect for use with factory audio or custom aftermarket systems.

R2 Amplifier Product Overview

Rockford Fosgate's R2 amplifiers are the building blocks for great audio systems, powerful enough to even DRIVE our Punch speakers and subwoofers. They have undergone an amazing upgrade by packing them with the latest features at an incredible value. Best of all, they are designed and engineered here in Tempe, Arizona.

TECHNOLOGIES

CEA-2006 Compliant
Power ratings on Rockford Fosgate amplifiers conform to the CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.

Full Range Class-D
A full-range version of the Class-D topology which is a high-efficiency amplifier design that reduces current consumption from the charging system.

P.O.W.E.R.
Power supply circuit design that allows the amplifier to increase output power as voltage increases.

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 the amp and optimise output.

Balanced Differential Inputs
Differential inputs eliminate noise picked up by signal cables.

MEHSA 4 (Maximum Efficiency Heat Sink Application)
MEHSA4 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

NOMAD
NOMAD is a "real-time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

CE Compliant
This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

Rollback Protection
During demanding musical conditions, the amplifier can dynamically reduce demand to prevent stress on the output devices.
