Why Choose Kicker 45KM44 Marine Speakers?
KM Series Marine Coaxials
Your cruise needs a soundtrack. KICKER KM Coaxial Marine Speakers make it loud, clear and fun!
Kicker Quality
The KICKER logo means it sounds great and will last for years. Whether your boat is in salt or fresh water, we know you need spectacular highs and lows to get that quality, full-range audio designed specifically for a marine environment.
Marine Made
KICKER went the extra mile to make these coaxials 100% marine-grade. Built from the ground up to be the best possible speaker for your boat, we added UV treatments to injection-molded cones and Santoprene® surrounds. We made splash-and-spray-resistant sealed motors, cones and locking/sealed terminal covers. Even the grilles have a built-in drainage port to prevent standing water. It’s all engineered to maintain top-shelf performance for years to come.
Frequently Asked Questions (FAQ)
- • Are these waterproof enough for my boat?
They are designed with marine-grade materials that resist water, UV rays, humidity, and corrosion. While they are built for marine environments, they should not be continuously submerged in water.
- • Why do the speakers sound distorted when I turn up the volume?
Distortion is often caused by amplifier clipping or incorrect gain settings rather than the speakers themselves. Matching them with an amplifier that provides clean RMS power will improve performance.
- • Can I use these with my factory marine receiver?
Yes. They work with most factory and aftermarket marine receivers that provide compatible power output.
- • Why is one speaker not producing any sound?
A loose wire, damaged speaker cable, or incorrect wiring polarity is usually the cause. Check every connection before assuming the speaker has failed.
- • Do I need an external amplifier for better sound?
No, an amplifier is not required for basic operation. However, adding one will provide cleaner output, higher volume, and better overall sound quality.
- • Why is the bass weaker than I expected?
Weak bass is commonly caused by reversed speaker polarity or an installation that allows air leaks around the mounting surface. Double-check the wiring and ensure the speakers are securely mounted.
- • Will these fit in my boat's existing speaker openings?
Fitment depends on your current cutout diameter and mounting depth. Compare your boat's speaker openings with the manufacturer's specifications before installation.
- • Why do I hear crackling or popping during playback?
Crackling usually indicates loose wiring, damaged speaker cables, or amplifier clipping. Inspect the wiring and test the speakers with another audio source if the problem persists.
- • Can I pair these with a marine subwoofer?
Yes. Adding a compatible marine subwoofer improves low-frequency performance while allowing the speakers to reproduce cleaner mids and highs.
- • How do I keep the speakers in good condition over time?
Rinse away salt residue when needed and inspect the wiring regularly for signs of corrosion. Proper maintenance and secure installation will help maximize their lifespan and performance.
