45KMF122 [Used]

The Kicker 45KMF122 is a 12-inch free-air marine subwoofer built to bring deep bass to a boat without a dedicated enclosure. Its two-ohm voice coil, injection-molded polypropylene cone, and co-molded Santoprene surround handle 350W peak and 175W RMS power, and a UniPlate back plate with a large ceramic magnet keeps output consistent. The polymer basket resists corrosion, the terminal cap protects the connections from spray, and stainless mounting hardware with a rear gasket are included for a clean, secure install. Built specifically for marine use, the subwoofer meets ASTM standards for UV and salt/fog exposure, so it holds up to sun and water season after season. A 5.5-inch mounting depth and 11-inch hole diameter make it a straightforward step up from a 10-inch sub in an existing free-air location, giving a boat noticeably more low end without reworking the cabin or deck.
