To set the gain on a 4-channel amp, start by turning off any equalizer settings and set the head unit volume to about 75% of its maximum. Adjust the gain for each channel by playing a test tone or music at a moderate level and slowly increasing the gain until you hear distortion, then slightly reduce it until the sound is clear. Repeat the process for each channel to ensure balanced audio output.
