45KMF102 10" Free-Air Marine Subwoofer with Hifonics TPS-A500.1 Mono Amplifier

This bundle pairs the Kicker 45KMF102 10-inch free-air marine subwoofer with a Hifonics TPS-A500.1 mono amplifier, giving a boat deep, controlled bass without the extra step of matching a sub and amp on your own. The 45KMF102 mounts directly into the boat's structure with no enclosure required, and its 2-ohm voice coil, injection-molded polypropylene cone, and co-molded Santoprene surround handle 350W peak and 175W RMS power while standing up to sun, spray, and humidity. A UniPlate back plate, large ceramic magnet, and corrosion-resistant polymer basket keep the subwoofer performing after seasons on the water, and it meets ASTM standards for UV and salt/fog exposure. The Hifonics TPS-A500.1 is built to power it: a 500W mono amplifier with ABYC and ASTM certified marine-grade protection, a conformal-coated circuit board, and gold-plated RCA inputs that resist corrosion from salt spray. A low-noise pre-amp stage keeps the signal clean, and quick-disconnect wiring makes it easy to pull the amp off the boat for winter storage or added security. Three-stage protection circuitry watches for thermal, overload, DC, and speaker-short conditions, so the setup keeps running through long days on the water. Together, the subwoofer and amplifier give a boat a complete bass upgrade already matched for power and impedance.
