Summary
Marine subwoofers use UV-resistant materials to prevent cone, surround, and grille degradation from direct sunlight.
Salt exposure accelerates corrosion, so marine models use coated hardware, sealed motors, and corrosion-resistant terminals.
Moisture resistance is critical. Marine subwoofers are designed to handle splashing, humidity, and condensation without internal damage.
A standard car subwoofer may work briefly in a marine environment, but long-term reliability depends on marine-specific construction.
