For complete protection, pair this stereo with a marine audio cover or mount it in a console to shield it from splash zones.

💡 Bonus Tip: Add Window Tint for Extra Comfort
Sunlight can wear down boat interiors and make your cabin uncomfortably hot. A great marine stereo deserves protection.
Professional car window tinting helps reduce heat, glare, and UV exposure. It also protects electronics like the MGV520B from overheating. Consider it the finishing touch for a better boating experience.
