45KM104 + RPB2-BLACK

This bundle pairs the Kicker 45KM104 10-inch marine subwoofer with a Rockville RPB2 handheld Bluetooth speaker, adding a portable audio option alongside the boat's built-in bass. The 45KM104 handles 175W RMS and 350W peak through a 4-ohm voice coil and a co-molded Santoprene surround built to ASTM UV and salt-fog standards, fitting sealed or ported enclosures between 1 and 2.4 cubic feet. The RPB2 is a compact aluminum-body speaker running Bluetooth 5.0, with a 40mm driver, hands-free calling through a built-in microphone, and an SD card slot for offline playback. Its 300mAh battery runs up to 5 hours at low volume and recharges in 30 to 40 minutes, and true wireless stereo lets you pair it with a second RPB2 for stereo sound. Between the two pieces, this bundle covers the boat's fixed low end and a portable speaker that can move from the cooler to the dock to wherever the day takes it.
