{"product_id":"memphis-prx500-4v2-4-channel-car-amplifier","title":"Memphis PRX500.4V2 4-Channel Car Amplifier","description":"\u003cp\u003eThe Memphis PRX500.4V2 is a four-channel car audio amplifier designed to add clean, controllable power to factory-replacement or aftermarket speaker systems. It delivers 75 watts RMS to each channel at 4 ohms or 125 watts RMS to each channel at 2 ohms. This makes it a practical choice for powering front and rear speakers from a compact amplifier chassis.\u003c\/p\u003e\u003cp\u003eFor systems that need more flexibility, the amplifier can also be bridged to produce 250 watts RMS across each of two 4-ohm channels. That arrangement can support a pair of higher-power speakers or a mixed system using speakers on one channel pair and compatible subwoofers on the other. Minimum supported loads are 2 ohms per channel in stereo operation and 4 ohms when bridged.\u003c\/p\u003e\u003cp\u003eThe PRX500.4V2 is built for users who want more output and tuning control than a head unit amplifier typically provides. Its frequency response extends from 10 Hz to 27 kHz, while adjustable high-pass and low-pass crossovers help direct the appropriate frequency range to each speaker. A variable EQ boost provides up to 12 dB of adjustment centered at 45 Hz.\u003c\/p\u003e\u003cp\u003eConnection flexibility helps the amplifier fit a wide range of vehicle audio systems. It accepts both preamp-level and speaker-level signals, allowing installation with many aftermarket radios as well as factory systems. A selectable 2-channel or 4-channel input mode can simplify signal routing when the source unit has limited outputs.\u003c\/p\u003e\u003cp\u003eThe Power Reference design combines a compact footprint with accessible setup controls. Its top-mounted controls sit beneath a removable panel, while blue LED lighting accents the top cover and under-mount area. The PRX500.4V2 is well suited to a speaker-focused upgrade or as part of a system that may later expand through its RCA preamp outputs.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel RMS Power:\u003c\/strong\u003e Supplies 75W x 4 at 4 ohms or 125W x 4 at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channel Pairs:\u003c\/strong\u003e Delivers 250W x 2 at 4 ohms when configured in bridged mode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters help match output to speaker duties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Supports RCA preamp signals and factory-radio speaker-level signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Turn-On Modes:\u003c\/strong\u003e Supports remote, DC-offset, and audio-sensing turn-on options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED-Accented Compact Chassis:\u003c\/strong\u003e Combines an extruded aluminum heatsink with concealed top controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe PRX500.4V2 uses an extruded aluminum heatsink chassis with blue LED top-cover and under-mount lighting accents. A removable top panel conceals the adjustment controls for a cleaner installed appearance while retaining access for system tuning. Protection circuitry is specified for overload, short circuit, thermal, and reverse-polarity conditions.\u003c\/p\u003e\u003cp\u003eMount the amplifier in a dry, ventilated location and verify speaker impedance before connecting outputs. Memphis specifies its 8GKIT as the recommended amplifier kit, and the manual requires a minimum 2-ohm stereo load or 4-ohm bridged load. Use RCA inputs for aftermarket source units, or the included speaker-wire-to-RCA adapters when integrating speaker-level outputs.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633196228678,"sku":"PRX500-4V2","price":299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51zYR57lb_L.jpg?v=1784413665","url":"https:\/\/audiowatt.store\/products\/memphis-prx500-4v2-4-channel-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
