To calculate the power of an audio amplifier, use the formula \( P = \frac{V^2}{R} \), where \( P \) is the power in watts, \( V \) is the RMS (root mean square) voltage output of the amplifier, and \( R \) is the load impedance in ohms, typically the speaker's impedance. Ensure that the amplifier's output voltage and the speaker's impedance are compatible to prevent damage and achieve optimal performance.
