Overview

Primed for Performance, the R2-300X4 is a 300 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.

The R2 models are 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 “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. These 3rd generation of Prime Series amplifiers are refined with the latest Rockford Fosgate technology for easy setup and configuration, making them perfect for use with factory audio or custom aftermarket systems.

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.

CE Compliant

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

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.

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.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

MEHSA⁴

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.
