Re: MRX-F30 wattage question
Yep, its perfectly fine. Usually you want about 10-25% more power than your speakers can handle for extra "headroom". This makes it so you are not stressing out your amp, even when you have your volume cranked. Most people don't realize your THD % goes up dramatically near the point of clipping.
