45KMF104 Subwoofer with dBM12 Mono Amplifier and RMWK4 Wire Kit

This bundle gives a boat everything needed to add serious bass in one order: the Kicker 45KMF104 10-inch free-air subwoofer, a Rockville dBM12 mono amplifier, and the RMWK4 4-gauge wiring kit to connect them. The subwoofer needs no enclosure and handles 350W peak, 175W RMS power on a four-ohm voice coil, with a co-molded Santoprene surround and corrosion-resistant polymer basket built for salt spray and UV exposure. The dBM12 supplies the power: a mono amplifier rated at 2,000W peak and 500W dyno-certified RMS, with a conformal-coated circuit board sealed with waterproof glue, silicone-covered terminals, and a rustproof aluminum heat sink so it holds up on the water. It ships with a bass remote for dashboard-level control and a 60-amp Maxi fuse sized for its output. The RMWK4 kit completes the install with 4-gauge power and ground cable, RCA and speaker cable, a fuse holder with a waterproof ring, and the terminals and ties needed to wire the amplifier in without hunting down parts individually. Together, the subwoofer, amplifier, and wiring kit turn one order into a finished, marine-rated bass system ready to install.
