Why Choose Kicker 45KM104 Marine Subwoofer?
High-Performance 4-Ohm Subwoofer Components
This subwoofer features a four-ohm voice coil for consistent power handling, a durable injection-molded polypropylene cone for accurate sound, a flexible co-molded Santoprene® surround for long-lasting performance, and a UniPlate™ back plate and pole piece to enhance heat dissipation.
Durable Marine-Grade Subwoofer Features
This subwoofer is built for marine environments with thick tinsel leads for reliable electrical connections, a large ceramic magnet for punchy bass, a corrosion-resistant polymer basket, a protective terminal cap to guard against moisture, and stainless steel mounting hardware for secure installation.
Marine-Ready Performance and Easy Setup
This subwoofer is marine-grade tested to exceed ASTM standards for UV and salt/fog exposure, offers simple configuration through the KICKERU app, and is optimized for 175 watts RMS in both sealed and ported enclosures.
Frequently Asked Questions (FAQ)
- • Can this marine subwoofer withstand saltwater, rain, and direct sunlight?
Yes. It is built with marine-grade materials that resist moisture, corrosion, and UV exposure for reliable long-term outdoor use.
- • Why does the bass sound weak after switching to a different enclosure?
An enclosure with the wrong internal volume or port tuning can reduce bass output. Use an enclosure that matches the recommended specifications for the best performance.
- • Can I install this in a sealed or ported enclosure?
Yes. It is designed to perform well in either enclosure type when the recommended enclosure volume and tuning guidelines are followed.
- • Why does it distort when the volume is too high?
Amplifier clipping or excessive gain settings are common causes of distortion. Proper amplifier tuning helps deliver clean bass while protecting the subwoofer.
- • Will it work with my existing marine amplifier?
Yes, provided the amplifier's power output and impedance match the subwoofer's specifications. Always verify compatibility before installation.
- • Why do I hear rattling when the bass gets louder?
Loose mounting hardware, enclosure vibration, or nearby boat panels can create unwanted rattles. Tighten all fasteners and inspect the installation area for loose components.
- • Does the subwoofer require a break-in period?
Yes. Playing music at moderate volume for several hours allows the suspension to loosen naturally and produce smoother bass response.
- • Why does the dust cap feel warm after extended playback?
A slight increase in temperature is normal during heavy use. Excessive heat may indicate overpowering or improper amplifier gain settings.
- • Can this be installed in a free-air marine application?
No. It is designed to perform best in a properly built enclosure that meets the recommended specifications. Using the correct enclosure helps maximize both performance and durability.
- • Why does the bass sound different depending on where I sit on the boat?
Boat layouts can create bass peaks and dead spots in different seating positions. Adjusting the enclosure location or phase setting can improve bass distribution throughout the listening area.

Great marine sub, just had some problems when installing it on my boat, but it still delivers nice bass, which is what I expected from a Kicker sub. Powerful for a 175-watt.
