It delivers 300 watts RMS at 4 ohms or 500 watts RMS at 2 ohms, making it suitable for a variety of subwoofer wiring configurations. Its compact chassis helps add dedicated bass amplification without requiring a large mounting area.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building or upgrading a vehicle subwoofer system, including systems retaining a factory radio. High-level input capability allows connection to compatible factory speaker wiring, while RCA inputs support aftermarket source units. A selectable auto turn-on feature can use DC-offset signal sensing when high-level inputs are used.\u003c\/p\u003e\u003cp\u003eIts full-range Class-D design is engineered for efficient operation from a vehicle's 12-volt electrical system. The mono output is fixed low-pass for subwoofer use, with a variable low-pass crossover to help blend the subwoofer with the rest of the system. A variable infrasonic filter can reduce very low frequencies sent to the subwoofer, particularly useful with vented enclosures.\u003c\/p\u003e\u003cp\u003eRockford Fosgate C.L.E.A.N. input and output indicators assist with gain setup by showing when input or amplifier output distortion begins. This provides a practical reference for setting source-unit volume and amplifier gain. The variable Punch EQ adds selectable bass boost at 45 Hz, so it should be adjusted carefully after basic gain setup.\u003c\/p\u003e\u003cp\u003eThe R2-500X1 can serve as the bass amplifier in a factory-radio upgrade or an aftermarket multi-amplifier system. Its RCA pass-through connections can simplify routing signal to another compatible amplifier. A wired remote level control is included for adjusting subwoofer output from the front of the vehicle.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W RMS Mono Output:\u003c\/strong\u003e Delivers up to 500 watts RMS into a 2-ohm subwoofer load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass-D Amplification:\u003c\/strong\u003e Provides efficient mono amplification in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.L.E.A.N.

Nickel-plated set-screw terminals are used for power, ground, remote, and speaker connections. Blue and red status indicators identify power operation and protection or thermal conditions.\u003c\/p\u003e\u003cp\u003eInstall the amplifier where its heat sink has at least 1 inch of surrounding air space, and mount it away from moisture and excessive heat. Use either the RCA low-level inputs or the high-level input harness, never both at once. The manufacturer specifies an 80-amp battery fuse, installed within 18 inches of the battery, and recommends keeping the chassis ground connection under 30 inches.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45641030041670,"sku":"R2-500X1","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71wEmwmhJnL.jpg?v=1784435303","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-r2-500x1-500w-class-d-mono-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
