Each PM100X1 uses the existing speaker-level output from a factory or aftermarket radio, helping simplify upgrades where running a conventional battery power cable is difficult. The kit is intended for vehicle, marine, and motorsports systems that need a compact amplification solution.\u003c\/p\u003e\u003cp\u003eEach amplifier delivers 60 watts RMS to a 4-ohm speaker or 100 watts RMS to a 2-ohm speaker. This added power can help replacement speakers play with greater output and control than they would from many radio-powered systems. The pair arrangement supports a straightforward two-speaker left\/right installation using one mono amplifier per channel.\u003c\/p\u003e\u003cp\u003eRockford Fosgate's BTL Powered FreeLoad technology harvests DC voltage and audio signal from standard head-unit speaker outputs. The amplifier stores available energy internally to provide dynamic output without normally requiring a separate positive battery lead. An optional B+ connection is included for installations with non-standard speaker outputs or insufficient available voltage.\u003c\/p\u003e\u003cp\u003eA selectable 2-ohm or 4-ohm input setting helps match the amplifier to the output capability of the connected radio. The built-in high-pass Butterworth crossover offers 60 Hz, 80 Hz, and 100 Hz selections to reduce low-frequency demand on smaller speakers. High-level turn-on operation supports integration with speaker-level source outputs.\u003c\/p\u003e\u003cp\u003eThe PM100X1K is built for installations exposed to moisture, including boats, motorcycles, ATVs, and other mobile applications. Its compact chassis, pigtail wiring, extruded aluminum heat sink, and IPX6 water-intrusion rating support placement in confined locations. It is a practical option for powering a pair of compatible full-range speakers without using a conventional large amplifier chassis.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePair Of Mono Amplifiers\u003c\/strong\u003e Includes separate amplifiers for left and right speaker channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreeLoad Power Design\u003c\/strong\u003e Uses radio speaker outputs for signal and operating power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100-Watt 2-Ohm Output\u003c\/strong\u003e Delivers up to 100 watts RMS per amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable High-Pass Filter\u003c\/strong\u003e Offers 60, 80, or 100 Hz protection settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2\/4-Ohm Input Selection\u003c\/strong\u003e Matches compatible factory or aftermarket radio output circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIPX6 Water Rating\u003c\/strong\u003e Suits moisture-prone marine and powersports installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eEach PM100X1 uses an extruded aluminum heat sink with convection cooling and discrete surface-mount construction. A Power\/Protect LED provides status indication, while thermal, short-circuit, and over-voltage protection help safeguard the amplifier.

Select the 2-ohm or 4-ohm input mode according to the source unit's speaker-output capability, and use the crossover selection appropriate for the connected speakers. Keep the chassis ground connection short, and use the supplied optional B+ wire only when the source output does not provide sufficient voltage for operation.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45637525798982,"sku":"PM100X1K","price":309.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61P7zWdH5wL.jpg?v=1784433342","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-pm100x1k-mono-marine-amplifier-pair","provider":"Audio Watt Store","version":"1.0","type":"link"}
