Yep. Smitty installed my CCS-100 with a 3 amp fuse, but that's about the smallest fuse that you can conveniently get from the local auto stores in the ATO/ATC format (though 1 and 2 amp fuses can be ordered by mail or on-line). The instructions that came with the Audiovox might show a smaller maximum current draw in their specs, but 3 amp seems to do.
