Hi, all, I have a couple questions about the watts rms differences that amps put out at different operating voltages? I was looking at specs on some of my amps, and some are rated at 12.5v and 14.4v.

My mtx 250x is rated 25 watts rms at 12.5volts while my coustic amp is rated at 45 watts rms at 14.4 volts.

How much power % wise is typically lost going from 14.4 volts to 12.5 or vice versa how much power is gained by going to the 14.4 voltage (if there is anyway to really compare). I am just trying to get an idea of how to better rate/compare the amps that I have.

Thanks for all the help!
