What Determines The Amount Of "Current" In An Amp?

.
For years I've heard that an amp needs lots of 'current' to drive certain speakers. What in an amps' design will determine current?

Also, how does current differ from watts per channel in the ability to drive a speaker?

Per Ohm's law, Current = Voltage/Resistance (I=V/R).

The less resistance in a circuit the more current (power to do work) for a given amount of voltage.

So current is power (and I thought it was knowledge!).
