For example, my jbl ms-62c components are rated for 80Wrms. My JL 5 channel amp provides 75 Wrms per speaker channel. This is within the 75-150 percent ideal & is thus fine & won't underdrive the speakers.

The gain had to be turned down for my JL 4" coaxials, b/c they were rated for 50 Wrms & thus the 75 Wrms per channel was riding the edge of too much power. Good thing is that with gain turned down, the speakers can be driven plenty well with good, clean power and the amp doesn't have to work as hard.
