45KM124 12" Subwoofer + RXM-T1 Amplifier + 4 Gauge Wire Kit

This bundle gives you everything needed to add real bass to a marine audio system: a 12-inch subwoofer, a 2-channel amplifier to power it, and a 4-gauge wire kit to hook it all up. The 45KM124 is built for a sealed or ported box, with 175W RMS and 350W peak handling on a 4-ohm single voice coil, an injection-molded polypropylene cone, and a co-molded Santoprene surround that resists UV and salt fog exposure. Stainless mounting hardware and a rear gasket come included for a clean install.

The RXM-T1 amplifier drives the subwoofer with 370W Dyno-Certified RMS bridged at 4 ohms, or 250W x2 in stereo, backed by a conformal-coated circuit board and stainless exterior screws that hold up to ocean spray. A high-speed MOSFET power supply, adjustable 12dB bass equalizer, and auto-turn-on high level inputs make it simple to wire into a boat that has no preamp outputs. The included 4-gauge wire kit supplies waterproof power, ground, RCA, speaker, and remote cable along with fuses and terminals, so the entire subwoofer and amplifier system installs from a single box.
