O(RMS) = 2 x 4, which means that the RMS output voltage from the audio power amplifier must be 2.83 V. Because the peak-to-peak output voltage of the CODEC is 3 …
Output Power of Audio Amplifier
https://amplifier.cd/Tutorial/Power/output_power.htm
Output power of audio amplifier The output power is a important characteristic for audio amplifiers. Introduction. Amplifiers have a specific power, which is indicated in Watts. The power is the product of current and voltage. In a loudspeaker the supplied electrical power is converted almost exclusively in heat.

Calculating RMS power: Wrms=Vrms^2/resistance (4.04^2)/8=2.04W 2.04W= RMS power. This is within 3W power rating of speaker. It is good to leave some headroom as in most audio applications the frequency, duty cycle, amplitude, and waveform will change and this may increase the power output.
