This may be a dumb question, but I am trying to find a way to display my amps output in volts, preferably like a volt meter displays your battery voltage. I thought I could just find an AC voltmeter and hook it to my amps outputs, like setting power output with a multimeter. I would like to be able to keep an eye on my output as my amp puts out more than double what my sub can take RMS. With the difference in level between different songs, I want to make sure i am running the power I am comfortable with. I found some AC meters but they were 110/220, I dont know if what I am trying to do is dumb, but I cant imagine nobody else has thought of this. Any help or info is greatly appreciated.
