Depends on the amplifier's power. A 100 watt output solid state amplifier
takes about 16-18 amps at 13.6 volts.
A 500 watt output solid state amplifier (like the Hercules II) takes five
times that much current at the same voltage.
Most amplifiers are not solid state but use vacuum tubes. Those amplifiers
usually come with their power supplies.
