FAQs
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.
