About the Kicker 49KM604WL
From our tech experts at CEN
Marine-grade 6.5 inch speakers, with UV-stable cones and corrosion-resistant hardware so they survive sun, salt and damp.
Who it suits
Boats, ribs and open vehicles, plus campers and outdoor builds where speakers live in the weather. Worth considering for any open-topped vehicle that sits outside.
Our tech experts advise
Marine installs live or die on the wiring: corrosion protection at every joint and a properly fused feed. Mounting location does more for the sound than the speaker choice. get in touch and we will talk through the layout. See car audio installation.

Frequently Asked Questions
Q: What makes marine speakers different from car speakers?
A: Marine speakers are built with UV-stable, water-resistant cones, grilles and hardware designed for open-air and wet environments. They are the right choice for boats, jet skis, hot tubs and outdoor installs.
Q: Are these speakers fully waterproof?
A: Marine speakers are water-resistant to marine ratings rather than submersible. The IP rating, where provided, is listed in the Specification tab.
Q: Do I need a marine amplifier as well?
A: For best results, yes. Marine amplifiers carry conformal-coated boards that resist moisture and salt air. Match the amplifier to the RMS rating in the Specification tab as you would with any system.
Q: Will these work outside of marine use?
A: Yes. Marine speakers are popular for motorcycles, quads, hot tubs, garden bars and anywhere the weather reaches. Their durability makes them a strong outdoor choice.
Q: How much power do the Kicker 49KM604WL speakers need?
A: Kicker recommends 15 to 50W RMS, with 150W peak power handling at 4 ohms.
Q: What size hole does the 49KM604WL need?
A: A 132 mm (5-3/16 inch) mounting hole with 62 mm (2-1/2 inch) of mounting depth.
Q: What colour are the 49KM604WL grilles?
A: White only. The white grille and basket are designed not to yellow or fade, and the speaker has built-in LED lighting.
