(2) 45KM124 12" 350W Marine Subwoofers + Mono Amplifier + Wire Kit

This package pairs two Kicker 45KM124 12-inch marine subwoofers with a Rockville dBM12 mono amplifier and a full 4 AWG wire kit, giving a boat serious low end without sourcing three separate products. Each KM124 sub uses an injection-molded polypropylene cone, a co-molded Santoprene surround, and a sealed motor structure built to handle sun, salt, and spray, with stainless mounting hardware and a protective terminal cap adding long-term corrosion resistance. The 12-inch driver works in a sealed enclosure between 1.25 and 3.5 cubic feet or a vented box between 1.75 and 2.25 cubic feet, giving an installer room to match the box to the boat. Driving both subs is the dBM12, a mono Class D amplifier rated at 2000 watts peak and 500 watts Dyno-Certified RMS at 2 ohms, with a conformal-coated board, waterproof silicone terminal covers, and a rustproof aluminum heat sink built specifically for marine use. A bass remote ships with the amp so you can adjust low end from the dash. The RMWK4 wire kit completes the install with waterproof 4-gauge power and ground cable, RCA cable, speaker wire, remote wire, and a fused mini-ANL fuse holder, covering the full run from battery to amplifier to subwoofer. Together, this kit turns a factory marine stereo into a system with real bass output, matched and ready to wire in one afternoon.
