Right, and I'm saying that the amp's maximum output is probably a lot less than the fuse rating. Stated another way, the fuse is most likely rated for a much higher amount of current than the amp can draw. That's on purpose, so that the fuse doesn't blow accidentally.

I'm just saying that, at best, looking at a fuse is a highly inaccurate way to determine the capabilities of the device that the fuse protects.

Also fuses are not only made for preventing fire if the power cables earth


Agreed, they are also made to protect the amplifier's internal components from problems, and to protect the car's electrical system from shorts in the amp itself.
