45KM104 + dBM65 + RMWK4 V2 + MRCA25 2-Pack

This bundle builds a multi-zone boat audio system around the Kicker 45KM104 10-inch subwoofer, adding a Rockville DBM65 6-channel amplifier, an RMWK4 wire kit, and two MRCA25 RCA cables to wire it up. The 45KM104 handles 175W RMS and 350W peak through a 4-ohm voice coil built to ASTM UV and salt-fog standards, fitting sealed or ported enclosures between 1 and 2.4 cubic feet. The DBM65 delivers 2,600W peak and 660W Dyno-Certified RMS across 6 channels, each with its own crossover supporting full-range, subwoofer, or midrange use, plus selectable 2, 4, or 6-channel input modes for receivers with limited RCA outputs. A conformal-coated PCB, waterproof silicone terminal covers, and stainless steel hardware protect the amp from salt spray, while an included bass remote and PA microphone add control and hailing capability at the helm. The RMWK4 kit and two MRCA25 cables supply the power, ground, speaker, and RCA wiring for the install. Between the four pieces, this bundle covers the subwoofer, a flexible amplifier capable of running several zones of speakers plus the sub, and the cable needed to connect it all.
