When purchasing a stereo system keep in mind that unless you are a "rocker" who has blown their hearing, just a few watts of power from a decent amplifier to quality speakers will be plenty of "sound" for the normal RV. One of the reasons for having a power amplifier rated for more than the normal listening level is that when the amp is run at a lower power lever the THD (total harmonic distortion) will be less. However, most of us over the age of fifty rarely can tell the difference due to hearing range loss as we age.
Another thing to keep in mind is that most manufacturers list the total peak-to-peak power of both channels. That means that each channel is 50-watts (peak-to-peak). Peak-to-peak is 2.828 times RMS (average power) so the total average power of each channel is approximately 17-watts. Ah, but that 100-watt amp must be really great! :)
