Reminder: how to tell current from an amp's specs?


I have a sinking feeling that I've been here before but, as the subject line says, how can I tell an amp's current from its published specs? 

Thanks!

Well, peak current is rarely specified.  We can learn the current specified at different speaker impedances, but the amp may be able to deliver more.

The power formula you want to use is:

 

Power = (Amps * Amps) * R

or:

 

square root of (power / R) = Amps

where R is the Ohms listed in the spec.
