okay... Gain.. NOT equal to "volume", as Knu was saying..
The gain matches the OUTPUT impedance (zo)of your HU to the INPUT impedance (zi) of your amp.
It is (correct me if I am wrong..) like telling the amp how much power to expect... so that it can be ready to amplify THAT amount to a higher level. You tell your amp to expect 1v, and it is ready to amplify it to 400w output, and then pump 2v in, you will clip your signal. The gain control just decreases the bias on the FETS inside the amp, therefore decreasing Ic. (Collector current).
(It's kinda like having extrude honed parts... matches the sizes EXACTLY, so that the air transfers most efficiently, and you get the most power out, with the least work..)
Well.. okay.. except that extrude honing doesn't care how many volts you have.. lolol
