Because I am not familiar with your vehicle, and because the location of the fuse box/panel varies from make to make, model to model, and even different year of manufacture for the same make and model this answer will be generic in nature and applies to most vehicles.
The following list of fuse box locations is generally in order of most often to least often used:
The 2005 Ford Focus power lock fuse can be found in the fuse box. The fuse box is located in the engine compartment. The location of the fuse will be listed on the inside cover of the fuse box.
The 2005 Dodge factory amp can be located in the fuse box. The location of the amp can be found on the inside cover of the fuse box.
The fuse box on a 2005 Expedition is located on the passenger side toe kick panel. There is a small access panel that can be pulled off to expose the fuse box.
