It provides a dedicated bass driver for systems where full-range speakers alone cannot reproduce the lower end with enough authority. Its selectable 2-ohm or 4-ohm impedance capability helps it fit a wider range of amplifier and wiring plans.\u003c\/p\u003e\u003cp\u003eThis model is intended for listeners building a compact marine or off-road system that needs substantial bass without moving to a larger subwoofer size. With 600 watts RMS power handling, it is suited to a properly matched external subwoofer amplifier. The 8-inch format can be useful where available mounting space is limited.\u003c\/p\u003e\u003cp\u003eThe MMJ824 uses a 2-inch voice coil, a 105-ounce magnet, and a die-cast aluminum basket to support high-power bass reproduction. Its published Thiele\/Small data includes a 40 Hz resonant frequency and a 0.59-inch linear Xmax rating. These characteristics support use in either sealed or vented enclosures built to the manufacturer's recommendations.\u003c\/p\u003e\u003cp\u003eMarine-focused materials include a UV-resistant polypropylene cone, plastic dust cap, rubber surround, gold-plated terminals, and a black stainless-steel grille. An RGB LED back-lit Memphis emblem adds visible accent lighting at the center of the subwoofer. The product is designed for marine and powersports environments, but it should still be installed and wired according to applicable equipment instructions.\u003c\/p\u003e\u003cp\u003eThe MMJ824 can be used as a single-subwoofer upgrade or paired with a second matching unit in a larger system. Memphis publishes enclosure recommendations for both single and dual sealed or vented configurations. Pair it with an amplifier that is stable at the selected impedance and whose RMS output is appropriate for the subwoofer's 600-watt RMS rating.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFLEX Selectable Impedance:\u003c\/strong\u003e Supports 2-ohm or 4-ohm system configuration flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600W RMS Handling:\u003c\/strong\u003e Accommodates a properly matched dedicated subwoofer amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRGB Back-Lit Emblem:\u003c\/strong\u003e Adds illuminated Memphis branding to the installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV-Resistant Polypropylene Cone:\u003c\/strong\u003e Uses a cone material suited to exposed installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie-Cast Aluminum Basket:\u003c\/strong\u003e Provides a rigid foundation for the moving assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack Stainless-Steel Grille:\u003c\/strong\u003e Adds front-side protection with a marine-oriented finish.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe MMJ824 combines a UV-resistant polypropylene cone, plastic dust cap, rubber surround, die-cast aluminum basket, gold-plated terminals, and black stainless-steel grille.

Select the desired 2-ohm or 4-ohm configuration to match an amplifier that is stable at that load, then use an appropriately sized sealed or vented enclosure. For a single subwoofer, Memphis recommends 0.65 cubic feet sealed or 1.1 cubic feet vented, with the vented design tuned to 40 Hz.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633186725958,"sku":"MMJ824","price":288.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81p2b5v7c7L.jpg?v=1784411271","url":"https:\/\/audiowatt.store\/products\/memphis-audio-mmj824-8-marine-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
