I want to know the relation between amplifier's output power vs speaker's usage. ex. if i have two 200 watts speakers what must be the minimum output power of my amplifier and ?
 
Solution
Anything less than 200W at the impedance of the speakers. The rating on speakers is a maximum. So a 50W amp could be perfectly fine. How loud those speakers get depends on the efficiency of the speakers and the input power. Efficiency and impedance are two other specifications for speakers that are just as important as wattage.
