The 501 oz magnet and cast basket keep the motor assembly rigid under sustained high-power use, and dual voice coil configurations in 1 ohm or 2 ohm give you the low-impedance wiring options that high-output amplifiers demand. At 90 lbs and a 10.8\" mounting depth, this is a driver built for dedicated enclosures — plan your box accordingly with a recommended ported volume of 3.824 ft³.\u003c\/p\u003e\n\u003cp\u003eThe XMAXXX Monster 15\" is purpose-built for SPL competition, high-output demo vehicles, and serious street builds where power handling and cone control are non-negotiable. Pair it with a high-output American Bass or VFL monoblock rated at 4000 watts or above for a properly matched system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tabitem\" id=\"Specifications\"\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eRMS POWER\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e4000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eMAX POWER\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e8000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eIMPEDANCE (OHMS)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003eD1\/D2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eSENSITIVITY DB\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e86.6\/87.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eMOUNTING DEPTH (IN)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e10.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eCUTOUT SIZE (IN)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e14.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003ePORTED BOX (FT³)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e3.824\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eMAGNET SIZE (OZ)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e501\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eVOICE COIL SIZE\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003e4\" \/ 3.9\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eBASKET TYPE\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003eCAST\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.6739%;\"\u003e\u003cstrong\u003eRECOMMENDED AMP (PAIR)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.657%;\"\u003eVFL 6K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4 style=\"text-transform: uppercase; color: #d92328; text-align: center;\" class=\"heading h4\"\u003eSupport\u003c\/h4\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0655\/3550\/8703\/files\/XMAX_Series_Subwoofer.pdf?v=1671568478\" style=\"color: #e20d0d;\" target=\"_blank\"\u003eSpecification Sheet (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"American Bass","offers":[{"title":"1 Ohm","offer_id":52386047557913,"sku":"XMAXXX-1511","price":1224.99,"currency_code":"USD","in_stock":true},{"title":"2 Ohm","offer_id":52386047590681,"sku":"XMAXXX-1522","price":1440.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0915\/5811\/7657\/files\/xmaxxx-monster-15-subwoofer-679146.jpg?v=1778701429","url":"https:\/\/www.alternatoroutlet.com\/products\/xmaxxx-monster-15-car-subwoofer-4000-watts-rms-dual-voice-coil-1-ohm-or-2-ohm","provider":"Alternator Outlet","version":"1.0","type":"link"}
