This sounds like a short in the wiring leading from the fuse to the amp itself.I have seen pinched,damaged and corroded wires cause this type of fault here needing repaired or replaced.I would trace and inspect the wiring to where it runs and leads to for any issues and repair any found to be at fault.If this was already done let me know.
