It delivers selectable RMS output based on the final speaker load, with ratings from 250 watts at 4 ohms to 750 watts at 1 ohm. This makes it a practical choice for adding controlled low-frequency output to a factory or aftermarket audio system.\u003c\/p\u003e\u003cp\u003eBuilt around a Class-D topology, the R2-750X1 is intended to provide substantial subwoofer power while managing demand on the vehicle electrical system. Its frequency response and low-pass crossover are tailored for bass reproduction rather than full-range speakers. The result is a focused amplifier platform for a dedicated subwoofer channel.\u003c\/p\u003e\u003cp\u003eThe amplifier accepts both low-level RCA and high-level speaker-level input signals, allowing it to work with many aftermarket radios as well as systems that retain a factory head unit. Balanced differential inputs help support clean signal integration, while RCA pass-through outputs can feed another amplifier. An auto-sense bypass switch is included for vehicles with retained accessory power.\u003c\/p\u003e\u003cp\u003eSetup features include Rockford Fosgate C.L.E.A.N. input and output indicators to assist with gain adjustment. A variable low-pass crossover, variable infrasonic filter, and adjustable Punch EQ let the installer shape the bass response around the subwoofer enclosure and listening preferences. The included wired remote level control provides convenient adjustment of subwoofer level from the driver’s seat.\u003c\/p\u003e\u003cp\u003eThe R2-750X1 fits well in a system built around one or more subwoofers with a final impedance of 1, 2, or 4 ohms. It is not bridgeable because it is already a single-channel amplifier. Proper power wiring, grounding, fuse protection, and subwoofer impedance matching are important for safe, reliable operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e750W RMS At 1 Ohm:\u003c\/strong\u003e Supplies up to 750 watts RMS to a properly matched mono subwoofer load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass-D Topology:\u003c\/strong\u003e Provides efficient subwoofer amplification in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Low-Level Inputs:\u003c\/strong\u003e Supports integration with factory or aftermarket audio sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.L.E.A.N.

Its top-mounted control panel keeps gain, crossover, EQ, and filter adjustments accessible after installation. Power, protection, and C.L.E.A.N. status indicators provide visual operating feedback.\u003c\/p\u003e\u003cp\u003eInstall the amplifier in a dry, ventilated location with space around the heatsink for airflow. Use up to 4 AWG power and ground wiring, up to 8 AWG speaker wiring, and a 120A fuse as specified; the fuse is not included. Match the connected subwoofer system to a 1-, 2-, or 4-ohm mono load, then set gain and filters carefully before regular use.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45641211150406,"sku":"R2-750X1","price":379.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71n748CxJZL.jpg?v=1784435403","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-r2-750x1-750w-mono-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
