To check the RMS (Root Mean Square) power of an amplifier, you can refer to the specifications provided by the manufacturer, which usually list the RMS power rating. If you want to measure it yourself, use a multimeter to measure the voltage across a load resistor connected to the amplifier's output, then calculate the RMS power using the formula \( P_{\text{RMS}} = \frac{V_{\text{RMS}}^2}{R} \), where \( V_{\text{RMS}} \) is the measured voltage and \( R \) is the resistance of the load.
