[QUOTE="bubbagumper6, post: 7677647, member: 567719"] Gain is to match the input voltage level ONLY. There's many different sources out there (different HU's, etc) and they all have different 'pre-out' voltages (2V, 4V, 6V, 8V, etc). With these different input voltages if the amplifier just linearly amplified the signal then you would get more power with a higher input voltage (not ideal). So the gain knob is used to compensate and adjust the amplifier to produce it's rated power level based on the input voltage. Thus, usually the higher input voltage you have, the LOWER the gain knob will need to be. If you want, you can think of the gain as a multiplier. If the amp is rated for 1000watts and your input voltage is 2V you'll need a multiplier of 500, but if you have an input voltage of 8V you would only need a multiplier value of 125 (thus a lower gain level). However this DOES NOT mean that you can just turn the gain knob up to get more output, once you reach your amp's rated power output anything higher will result in a clipped output which is undesirable to say the least.
