It delivers up to 300 watts RMS to a 1-ohm load while measuring just 1.53 by 4.25 by 6.75 inches. Its low-pass-only design makes it suited to focused bass-system upgrades.\u003c\/p\u003e\u003cp\u003eThis amplifier is a practical fit for cars, trucks, motorcycles, ATVs, hybrids, and other installations where mounting room is at a premium. It supports both RCA low-level and speaker-level input connections, allowing it to work with many aftermarket and factory audio systems. A selectable high\/low input mode helps match the installation method to the source unit.\u003c\/p\u003e\u003cp\u003eThe PBR300X1 provides 75 watts RMS at 4 ohms, 150 watts RMS at 2 ohms, and 300 watts RMS at 1 ohm. Its variable low-pass crossover lets the installer set the upper bass cutoff from 35 Hz to 250 Hz. This helps blend a connected subwoofer with the vehicle's main speakers.\u003c\/p\u003e\u003cp\u003eRockford Fosgate Class BR Boosted Rail technology is used to deliver its output from a very small chassis. The amplifier uses a MOSFET output stage, an extruded aluminum heatsink, and convection cooling. Power\/Protect and BRT status LEDs provide visible operating feedback from the top-mounted control area.\u003c\/p\u003e\u003cp\u003eFor factory-radio integration, the amplifier includes speaker-level inputs and a variable 4 to 6 volt DC-offset turn-on adjustment. An optional Rockford Fosgate PEQ remote can control the amplifier's Punch EQ bass boost circuit. With appropriate wiring, fusing, and a correctly matched subwoofer load, the PBR300X1 can serve as the bass amplifier in a compact system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Mono Design:\u003c\/strong\u003e Fits in space-constrained vehicle audio installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Ohm Stable Power:\u003c\/strong\u003e Delivers 300 watts RMS at 1 ohm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass BR Topology:\u003c\/strong\u003e Supports compact boosted-rail amplifier engineering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Inputs:\u003c\/strong\u003e Connects to factory speaker-output signals when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts bass crossover from 35 Hz to 250 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional PEQ Remote:\u003c\/strong\u003e Enables remote control of Punch EQ bass boost.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe PBR300X1 uses an extruded aluminum heatsink to dissipate heat, with convection cooling rather than a fan. Its small enclosure measures 1.53 inches high, 4.25 inches wide, and 6.75 inches long. Top-mounted status LEDs indicate power\/protection status and Boosted Rail operation.\u003c\/p\u003e\u003cp\u003eUse a subwoofer wiring configuration that presents no lower than a 1-ohm load, and select the matching power rating when choosing a subwoofer. Rockford Fosgate recommends 10 AWG wire for the amplifier's power and ground connections and specifies a 30A external battery fuse. Mount it outside the engine compartment with adequate ventilation; installations under a seat require at least 1 inch of air gap around the heatsink.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45637029265478,"sku":"PBR300X1","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71TdBpJfxrL.jpg?v=1784433094","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-pbr300x1-compact-mono-subwoofer-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
