Amplifiers take a signal from the stereo and use an independent power source to change it into a more powerful signal for the speakers. The reason for this is that the NFB constrains the amp to a fixed value of gain. One other thing to keep in mind is many RV appliances require more amps to start the appliance than they do to run the appliance. This is often not known by users. Distortion can occur at almost any point in the audio pathway, from the microphone to the speaker. Speakers with Chromecast built-in. This type of connection establishes a low/no impedance path to ground.
