I hate in-line fuses as a practical matter; they're a pain to secure properly with the wire and then easily access their contents. I much preferred it when most components came with the fuse incased in the back panel of the component,
That being said, it should be emphasized that they, or a suitable replacement for them are necessary. You can install a breaker or fuse for each circuit not to exceed that required by the wire and thus protect the wire, while doing nothing to protect the component. If you have a seperate circuit for each component, there is nothing wrong with having 12 gg wire with a 1 amp fuse reflective of the component's requirements. If, as is common, you're to have multiple components coming off the same circuit, the fuse should be of a size reflecting that of the lowest rated component. Since that practise results in the lowering of the utility of that circuit, ie..how many things you can place on it, it's perhaps best to fuse or size the breaker for the wire and fuse each component seperately at the component.
Anotherwords, Don't cut off those in-line fuses and throw them away without planning for adding similar fusing capability elsewise in their replacement! Remember that the tendency will be, when confronted with a single fused circuit, to apply a larger fuse at some future date, thus jeopardizing all unfused componnents down line.
