Details about the Rockford Fosgate R2-300X4
Primed for Performance, the R2-300X4 amplifier is a 300 watt, full-range class-D, 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.
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.
The Prime Series were 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. 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.
