Watts vs. Amps

I have seen many times that some speakers do not need Watts as much as they need Amps. This confuses me each time I read it. When I studied electricity in high school & college we were told that Watts equal Amps times Volts: (W = A x V), And since the Volts are staying the same shouldn't an increase in Watts cause a proportional increase in Amps and vice versa?
Am I being too simple with my thinking? There must be something I'm missing right?
Please let me know what I am not seeing. Oh, and please use small words and talk/type slowly for me.
