Maintenance Tips

• Rinse gently with fresh water after saltwater exposure to prevent corrosion buildup.
• Clean regularly with a soft microfiber cloth; avoid abrasive materials that can damage the marine-grade finish.
• Ensure all stainless steel hardware and mounting points remain tight and corrosion-free.
• Check seals and gaskets periodically to maintain water resistance and prevent moisture ingress.
• Avoid directing high-pressure water jets directly at the tweeter or woofer.
• Inspect wiring connections for oxidation and apply marine-grade dielectric grease if needed.
• Do not exceed rated power handling to prevent distortion and long-term driver damage.
• Keep drainage paths and mounting surfaces clear to avoid water pooling.
• Allow speakers to dry fully after cleaning or heavy spray exposure.
• Store or cover when not in use for extended periods to extend marine durability.
