Designed for optimal performance, the R2-300X4 is a 300-watt full-range Class-D amplifier that works with 4Ω or 2Ω stereo configurations, as well as 4Ω bridged/mono setups. Thanks to its Class-D design, this amplifier operates with high efficiency, minimizing strain on your vehicle’s electrical system. It also includes C.L.E.A.N. circuitry, which makes it easier to fine-tune your gain settings, and a P.O.W.E.R. supply that boosts power output as the voltage rises.
