Power = Voltage * Current, so halving the available voltage will double the current requirements (for the same power).  
 
When your European amp runs from 220 V, it draws half the current it does than when it runs from 110 V, and the 2A fuse was adequate. But with 110 V, it will draw twice the current and blow the 2A fuse. That's why they stuck 4A fuses in the export amps.
