amplifiers are connected to the headunits with high-voltage pre-outs, the signal is not clipped or distorted if the gain control is set to proper position, so high S/N (Signal-to-Noise) ratio is realized in the speaker level signal. To ensure continuous audio output, the amplifier's gain control must be set according to the pre-out maximum output level of the headunit. There is no need to decrease the volume of the headunit, as too much output will be controlled.  (less)
