well sort of...
think of this.. the head unit primarily puts out the sound. the gain just amplifies that sound to a degree. So if you put the head unit volume on max and it distorts and then u put the gain up.. it will increase amplification of the distorted volumes. thus its important to have a super clean signal going to the amps for that to amplify using the gains.
will i thought you would know this shiznit?!!
