You can mount it behind a panel, under a seat, or in any protected storage area. It operates reliably even in high humidity or vibration-heavy environments.

💡 Protect Your Gear and Interior with Window Tint
Marine electronics can overheat in the sun or degrade from UV exposure. Protect your equipment with quality window tint. Tinted glass helps reduce interior temperatures and blocks harmful rays.
This improves comfort and extends the life of your audio system. It also minimizes glare on screens and enhances privacy.
We recommend Window Tint Delaware for high-performance marine window film. Their technicians provide professional installation and durable tint solutions.
