2004 Ford Explorer

Universal gear includes car amplifiers, subs, and other products that do not install in a specific location or require fitment to integrate with a vehicle.

Universal-Fit Audio for 2004 Ford Explorer

When thinking of universal gear, we consider products like a car amp that gives more power to your speakers or subs, cell phone chargers, equalizers and sound processors, rear-seat entertainment and video monitors, as well as dash cameras.
