figure out how many watts it'll be putting out at whatever load you have it wired down to.. (2 or 4 ohms etc)
take the total watts, and divide by 12

take that total and multiply by 1.2 for a class D or T amp
or by 1.4 for a class AB amp.
that's your fuse rating in amps.

1200 watt class D amp
1200/12 = 100
100 * 1.2 = 120A fuse
