🌞 Keep Your Audio Investment Safe
Heat and sunlight can reduce car subwoofer life and affect performance. That’s why we recommend car window tinting to protect your interior and electronics.
Window tint keeps your car cooler, protects audio gear from UV damage, and offers extra privacy. It’s a smart upgrade to pair with your new subwoofer installation.
