It provides dedicated amplification for front and rear speakers, helping a system play with greater control and output than a head unit’s built-in amplifier. With 300 watts of total rated RMS power, it is designed for compact multi-speaker installations.\u003c\/p\u003e\u003cp\u003eThis amplifier is well suited to drivers replacing factory door speakers or building a balanced front-and-rear speaker system. It delivers 50 watts RMS to each of four channels at 4 ohms, or 75 watts RMS per channel at 2 ohms. Each front\/rear channel pair can also be bridged for higher-power two-channel configurations using compatible 4-ohm loads.\u003c\/p\u003e\u003cp\u003eClass-D topology helps reduce electrical demand while keeping the amplifier compact. The R2-300X4 has a 20 Hz to 20 kHz frequency response for full-range speaker use, making it appropriate for component speakers, coaxials, and other midrange\/high-frequency applications. Adjustable front and rear crossovers allow the system to be configured around the speakers and any separate subwoofer system.\u003c\/p\u003e\u003cp\u003eRockford Fosgate C.L.E.A.N. circuitry uses input and output clip indicators to assist with gain setup. Balanced differential inputs, high-level input capability, and a 2\/4-channel input switch support integration with a variety of factory and aftermarket source units. RCA pass-through outputs can feed an additional amplifier when expanding the system.\u003c\/p\u003e\u003cp\u003eThe R2-300X4 is built for practical system upgrades rather than requiring a complex signal chain. Its selectable Punch EQ, variable gain controls, and top-mounted adjustment panel make it easier to fine-tune a four-speaker installation. A compact chassis and convection cooling support installation in many vehicle locations with suitable ventilation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class-D Power:\u003c\/strong\u003e Delivers 50 watts RMS per channel at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channel Pairs:\u003c\/strong\u003e Supports 150 watts RMS x 2 at 4 ohms bridged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.L.E.A.N.

Its compression terminal blocks provide secure power and speaker connections, while the top-mounted controls keep setup adjustments accessible after installation. Power, protect, and C.L.E.A.N. status indicators provide visual operating feedback.\u003c\/p\u003e\u003cp\u003eUse 4 AWG power and ground wiring with a properly installed 60-amp fuse, and use suitable speaker wire up to 8 AWG. The amplifier accepts RCA preamp signals or high-level speaker signals, making it suitable for many factory-radio and aftermarket-radio installations. Mount it securely in a ventilated location, and configure its front and rear crossover sections to match the speakers and overall system design.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45640914960454,"sku":"R2-300X4","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71b4UILM1TL.jpg?v=1784435254","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-r2-300x4-4-channel-class-d-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
