    Dumb question but read this anyway...

    The only way to have a amp reach it's Max RMS (not Max/Peak) wattage is to run gains at full. But running gains at full is not recommended... so basically u don't really even get the full RMS rating going to your subs... (if u don't run gains at full)???

    You do not max the gains to get max power out of an amp. In fact if you have a sufficiently high input level voltage, you can get max power out of an amp with the gains at their absolute lowest.

    are you talking about the voltage from the alternator? or from the headunit's preouts...

    Re: Dumb question but read this anyway...

    So if ur deck is 4 volts and ur amp has output of 9volts... u want to keep gains approximately a little under half...

    Re: Dumb question but read this anyway...

    Chances are the 4V is max not rms. Also, the volume on your HU and the gain on your amp are not linear controls(ie half of 4 volts is not 2, sound weird but thats the way it works). The only way to accurately set the gain is with a multimeter at least and an occilloscope (sp?) at best.
