Anonymous | How do you calculate how many watts rms a amp is putting out?Volts and the fuses on the amp?EX:14.4v x 60A=864watts rms, is this right? |

If you want to test the true power, you'll need a voltmeter on hand, and a resistor for an impedance load. Use the instructions here: http://www.bcae1.com/measpwr.htm |

Anonymous | Well that is what you said in one of your post(Archive through June 30;12" volfenhag;7 post)I just thought that it was right since you posted it. |

It balances out when efficiency is factored in. Anyway, the above is the proper way to measure RMS. |
