45KMF104 Subwoofer, 45KMG10C Grille, and RXM-T1 Amplifier

This bundle pairs the Kicker 45KMF104 10-inch free-air marine subwoofer and matching 45KMG10C charcoal LED grille with a Rockville RXM-T1 2-channel amplifier, covering the bass, the finished look, and the power in one order. The subwoofer needs no enclosure and is rated for 350W peak, 175W RMS 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 charcoal grille is molded from thick, waterproof ABS plastic sized specifically for the 10-inch subwoofer and ships with silicone-coated LEDs already built in. The RXM-T1 supplies the power: 1,500W peak and 370W dyno-certified RMS from a conformal-coated, marine-rated amplifier with a high-speed MOSFET power supply and studio-grade bipolar output transistors. Smart auto turn-on senses a signal from the head unit so no separate remote turn-on wire is needed, and full IC-controlled protection circuitry keeps the amp running safely at higher volumes. Stainless exterior screws and a conformal-coated circuit board protect the amplifier the same way the subwoofer and grille protect themselves, so the whole system is ready for a boat from day one.
