It provides four amplified channels for full-range speakers, helping a system achieve stronger output than a source unit can typically supply on its own. Its compact housing supports installations where available mounting space is limited.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for riders and installers building or expanding a powersports audio system with multiple speakers. It delivers 75 watts RMS per channel at 4 ohms or 100 watts RMS per channel at 2 ohms, making it suitable for matching with compatible full-range speakers. It can also be bridged to provide two 200-watt RMS channels at 4 ohms.\u003c\/p\u003e\u003cp\u003eThe MX400-4 is built for applications exposed to water, dust, and changing outdoor conditions. Its IP66-rated water and element resistance, conformal-coated circuit board, and sealed connectors support use in demanding powersports environments. A protective cover over the top-mounted controls helps keep the tuning area shielded while maintaining access during setup.\u003c\/p\u003e\u003cp\u003eFor system tuning, the amplifier includes a fixed 80 Hz crossover and supports both high-level and low-level input compatibility. Its 2\/4-input switch can simplify signal routing when connecting compatible audio sources. The 10 Hz to 20 kHz frequency response allows the amplifier to cover the normal full-range signal spectrum used by compatible speaker systems.\u003c\/p\u003e\u003cp\u003eThe MX400-4 fits naturally into a staged powersports upgrade, whether powering four speakers directly or operating as a bridged two-channel amplifier. It is specified for use with Memphis' recommended 8GKIT amplifier wiring kit. Proper speaker impedance, secure mounting, and protected power wiring are important for a reliable installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Output:\u003c\/strong\u003e Powers up to four compatible full-range speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e75W x 4 RMS at 4 Ohms:\u003c\/strong\u003e Provides continuous power for properly matched speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Operation:\u003c\/strong\u003e Delivers 100W x 4 RMS at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channels:\u003c\/strong\u003e Supports 200W x 2 RMS at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP66 Resistance:\u003c\/strong\u003e Helps protect the amplifier from water and elements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed 80 Hz Crossover:\u003c\/strong\u003e Provides a defined crossover point for system setup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MX400-4 uses a compact chassis measuring 8.75 by 3.25 by 1.75 inches. Its conformal-coated board, sealed connectors, and protected top-mounted controls are designed for powersports applications where exposure resistance and packaging flexibility matter. The amplifier carries an IP66 water- and element-resistance rating.\u003c\/p\u003e\u003cp\u003eInstall the amplifier in a secure location with appropriate ventilation and protected wiring paths. Use compatible high-level or low-level source connections, match speakers to supported 2- or 4-ohm operation, and use the recommended 8GKIT wiring kit. When bridging channels, use a 4-ohm speaker load per bridged channel pair and follow the manufacturer wiring guidance.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633187905606,"sku":"MX400-4","price":299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51RTvCyuCOL.jpg?v=1784411905","url":"https:\/\/audiowatt.store\/products\/memphis-mx400-4-4-channel-powersports-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
