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

This package combines two Kicker 45KM124 12-inch marine subwoofers with an MTX WET500.1 mono amplifier and a full 4 AWG wire kit, covering the sub, amp, and wiring a boat or off-road build needs for real bass in a single order. Each KM124 sub uses an injection-molded polypropylene cone and a co-molded Santoprene surround, with a sealed motor structure and stainless mounting hardware that resist sun, salt, and spray. The 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. Power comes from the WET500.1, a compact Class D mono amplifier rated at 1000 watts peak and up to 500 watts RMS at 2 ohms, built with a conformal-coated circuit board and an IP55 weather rating so it holds up on a boat, ATV, or UTV. A variable 40Hz to 220Hz crossover lets you tune the amp specifically for a 12-inch subwoofer, and stainless hardware with rubber gaskets around every connector protects against corrosion. The RMWK4 wire kit finishes 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. Because the amplifier's small chassis fits where a full-size unit can't, this bundle works as well tucked under a boat seat as it does mounted in a side-by-side dash.
