It is suited to installations that need more output than a source unit can provide while retaining flexible speaker-system options. Its 600-watt total RMS rating supports full-range speakers, subwoofers, or a combination of both.\u003c\/p\u003e\u003cp\u003eThis amplifier can operate as a conventional four-channel model, a bridged two-channel model, or a three-channel system with front speakers and a bridged rear subwoofer channel pair. It delivers 75 watts RMS to each channel at 4 ohms or 150 watts RMS to each channel at 2 ohms. When bridged, it provides 300 watts RMS per pair at 4 ohms.\u003c\/p\u003e\u003cp\u003eIts Class A\/B circuit topology is intended for detailed full-range amplification, with a frequency response rated from 20 Hz to 20 kHz. Adjustable high-pass and low-pass crossovers help direct appropriate frequencies to speakers or subwoofers. Front and rear Punch EQ controls provide bass and treble adjustment for system tuning.\u003c\/p\u003e\u003cp\u003eThe PM600X4 is built for use around water, dust, and changing temperatures in marine and powersports environments. It uses a conformal-coated circuit board with a marine-grade two-part epoxy coating, marine-grade stainless-steel hardware, and a cast-aluminum heatsink. Convection cooling and protection circuitry support dependable operation in properly installed systems.\u003c\/p\u003e\u003cp\u003eFor system expansion, the amplifier provides high- and low-level input capability, automatic turn-on capability with high-level inputs, and RCA pass-through outputs. Its C.L.E.A.N. setup system uses clip indicators to help set amplifier gain appropriately. An optional Rockford Fosgate PLC2 Punch Level Control can be added for convenient level adjustment.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel RMS Power:\u003c\/strong\u003e Delivers 75 watts x 4 at 4 ohms or 150 watts x 4 at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Operation:\u003c\/strong\u003e Combines channel pairs for 300 watts x 2 at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass A\/B Topology:\u003c\/strong\u003e Supports full-range speaker and mixed speaker-subwoofer system designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters help match output to connected speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Construction:\u003c\/strong\u003e Coated circuitry and stainless hardware support marine and powersports use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.L.E.A.N.

Its top-mounted control panel keeps adjustments accessible while maintaining a clean installation appearance. The circuit board receives a marine-grade two-part epoxy coating, and the amplifier uses marine-grade stainless-steel hardware.\u003c\/p\u003e\u003cp\u003eUse 4 AWG power wiring and install the recommended 100-amp fuse in the main power run. The amplifier accepts high- or low-level signal input through two pairs of RCA inputs and provides one pair of RCA pass-through outputs. Match stereo channels to 2- or 4-ohm speaker loads, and use only a 4-ohm load per bridged channel pair.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45637981470790,"sku":"PM600X4","price":649.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61_PpTWAm4L.jpg?v=1784433572","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-pm600x4-4-channel-marine-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
