Overview R2-300X4
The Prime R2-300X4 is a full-range class-D 4-channel amplifier, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono and rocking 300 Watts of RMS power. 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 and the unique P.O.W.E.R. supply continues to generate more than the rated power as the voltage increases.
The Prime Series was developed for car audio fanatics that want a reliable amplifier that won't break the bank – with all the power and performance you've come to expect from Rockford Fosgate.
