{"product_id":"memphis-mx400-4","title":"MEMPHIS MX400-4 4-Channel Powersports Amplifier","description":"\u003cp\u003eThe Memphis MX400-4 is a compact four-channel powersports amplifier designed to add clean, flexible amplification where space is limited. It is built for side-by-side, ATV, motorcycle, and similar off-road audio installations that need more output than a source unit can provide. Its weather-resistant construction helps support dependable installation in exposed vehicle environments.\u003c\/p\u003e\u003cp\u003eWith 75 watts RMS per channel at 4 ohms or 100 watts RMS per channel at 2 ohms, the MX400-4 can power front and rear speakers from one compact chassis. It can also be bridged to two channels at 200 watts RMS each into 4 ohms. This makes it useful for full-range speaker systems, or for systems that need a more focused two-channel configuration.\u003c\/p\u003e\u003cp\u003eThe amplifier uses efficient Class D technology and has a 10 Hz to 20 kHz frequency response for full-range system use. Independent front and rear sensitivity controls allow the amplifier to be matched to the output level of the source unit. A selectable 2-channel or 4-channel input mode can simplify wiring when the source provides only one pair of audio outputs.\u003c\/p\u003e\u003cp\u003eIts IP66-rated chassis, conformal-coated circuit board, and sealed connectors are engineered for resistance to dust, water spray, and the elements. A protective top cover shields the tuning controls while keeping them accessible after installation. The compact chassis is especially practical for tight mounting locations common in powersports vehicles.\u003c\/p\u003e\u003cp\u003eThe MX400-4 accepts both low-level RCA and speaker-level input signals, helping it integrate with aftermarket or factory-style source units. Fixed 80 Hz high-pass and low-pass crossover options help direct the appropriate frequency range to connected speakers. Pair it with properly matched speakers, a suitable 8-gauge amplifier wiring kit, and a fused power connection for a complete powersports audio upgrade.\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 speakers from one compact amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass D Design:\u003c\/strong\u003e Provides efficient full-range amplification for powersports systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP66-Rated Chassis:\u003c\/strong\u003e Helps resist dust, water spray, and outdoor conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConformal-Coated Board:\u003c\/strong\u003e Adds protection for internal electronics in exposed installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed 80 Hz Crossovers:\u003c\/strong\u003e Supports high-pass, low-pass, or full-range channel setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- And Low-Level Inputs:\u003c\/strong\u003e Connects with RCA-equipped or speaker-level source units.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MX400-4 uses a compact weather-resistant chassis with sealed connectors, a conformal-coated circuit board, and a protective cover over its top-mounted controls. These details support use in powersports applications where vibration, dust, and water exposure are common considerations. Its status LED indicates normal operation or protection status.\u003c\/p\u003e\u003cp\u003eMount the amplifier in a secure location with practical access to the control cover and adequate cable routing. The recommended Memphis 8GKIT wiring kit is specified for installation, while an 8-gauge power and ground connection with a 40A fuse is recommended. Use the included input harness that matches the source signal type, select 2-channel or 4-channel input mode as needed, and set each channel pair to high-pass, low-pass, or full-range operation.\u003c\/p\u003e","brand":"MEMPHIS","offers":[{"title":"Default Title","offer_id":45843353862335,"sku":"MX400-4","price":152.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/6252\/4351\/files\/MX400.4-5.jpg?v=1783904500","url":"https:\/\/nsidistributor.com\/products\/memphis-mx400-4","provider":"NSI Audio Distributing","version":"1.0","type":"link"}
