is there a difference between amp watt and speaker watts ?

[Jack1998]

How much wattage would a 200 watt amp give to my speakers, my guess is 200 watt

A MAXIMUM of 200W. Most of the time much less. Obviously, the volume you play at determines a lot of the power used. It also depends on the impedance of the speaker. The 200W rating is for a specific impedance of speaker.

Assuming a non-crappy amplifier:
For normal listening levels, 5 watts.
For shake the house, 15 watts
For marketing purposes, 200 watts.
