Take a look at the power blocks sold for RV use. I've got one in the rack cabinet holding my scanners and it works a treat; uses standard automotive blade fuses and made the wiring so much neater. Also have one in the truck for all the aftermarket stuff (ham rig, amplified scanner speaker, etc), and another in my portable battery box.
