Fuses usually have to conduct vastly more current than the miniscule amount that is conducted by these wires. Also, in many and perhaps the majority of applications the current through a fuse varies dynamically with the music, and as it does so the resistance of a fuse varies significantly, which can potentially cause a multitude of effects. Those effects will not occur in these wires due to the essentially negligible amount of current they are conducting. Also, the effects of a fuse in many and perhaps most applications can occur at any and all frequencies, rather than just in the deep bass region. Fuses in audio components involve completely different situations than this one.
