A gain knob allows you to match the output of the head unit (at full volume) to get the full volume of the amp at the same time. EX: If the head unit produces 4 volts at full volume you want the amp to be at full volume with 4 volts of input, not at 3 or 2 volts. If so then it will run into clipping at 1/2 or 3/4 volume because of being over driven by the head unit. If your not getting the required result from your speakers chances are that your amp don't produce enough power to adequately push them. |

They can range from 250mV to 16V in cars. If you want to learn how to set "gain" properly, go to www.jlaudio.com go to the tutorials section, and read the guide there. I have links to half a dozen other guides on the subject as well if needed. more on amplifier basics: http://www.wickedcases.com/caraudio/amplifiers.html |
