This 12-inch free-air subwoofer mounts directly into a panel and uses the air space behind it as its enclosure. That means you can put real bass under a helm, in a gunwale or in a seat base without giving up storage. Its 5.5-inch mounting depth fits where enclosed subs won't.\u003c\/p\u003e\u003cp\u003eIt's built for South Florida conditions. Kicker tests the KM sub line to ASTM B117 (200-hour salt fog) and ASTM G154 (400-hour UV). The injection-molded polypropylene cone, co-molded Santoprene surround and polymer basket are made to handle sun, spray and humidity. A protective terminal cap and stainless mounting hardware keep the install clean and corrosion-free.\u003c\/p\u003e\u003cp\u003eThis is the 4-ohm version (45KMF124). That makes it easy to pair with a marine amp channel or bridge a 4-channel amp. Kicker recommends about 175 watts RMS. If you want it to light up after sunset, add the KMG12 LED grille.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBest for:\u003c\/b\u003e center consoles, bay boats, pontoons and wake boats that want deeper bass without a box.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSize: 12\" (30 cm), single 4-ohm voice coil (45KMF124)\u003c\/li\u003e\n\u003cli\u003eRecommended amp power: 175W RMS; peak 350W (ANSI\/CTA-2031-A)\u003c\/li\u003e\n\u003cli\u003eFrequency response: 30–500 Hz\u003c\/li\u003e\n\u003cli\u003eMounting depth: 5.5\"; cutout 11\"; outer diameter 13\"\u003c\/li\u003e\n\u003cli\u003eFree-air: no enclosure required\u003c\/li\u003e\n\u003cli\u003eASTM B117 200-hr salt fog and ASTM G154 400-hr UV tested\u003c\/li\u003e\n\u003cli\u003eStainless mounting hardware, protective terminal cap\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eDo I need a subwoofer box for the KMF12?\u003c\/h3\u003e\u003cp\u003eNo. It is designed for free-air mounting, so it plays off the sealed space behind the panel you mount it in.\u003c\/p\u003e\u003ch3\u003eWhat amplifier should I use?\u003c\/h3\u003e\u003cp\u003eKicker recommends about 175W RMS at 4 ohms, such as a channel pair bridged from a Kicker KMA360.4.\u003c\/p\u003e\u003ch3\u003eWhat size hole do I cut?\u003c\/h3\u003e\u003cp\u003eThe cutout is 11\" with a 13\" outer diameter and 5.5\" mounting depth.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Ocean Rock Audio\u003c\/h2\u003e\u003cp\u003eOcean Rock Audio is South Florida's Kicker marine boat speaker specialist and an authorized Kicker dealer, so your purchase carries the full Kicker manufacturer warranty.
