Unbalanced amp

[Youhearthat? 10+ year member]

OK this is a JL audio e6450...

The thing is that I am triying to set the gains of the amp with the required voltage but the amp does not put out the same voltage in the left and right channels there is a difference of .5 volts... Unless I tweak with the gains and I move them around then both left and right channels settle [sometimes] and put out the same voltage and what I mean by tweaking is that I just move the knob around and then return it to the desired voltage... what should I do? I tought it was supposed to put the same voltage on left and right outputs... and I need to fiddle around with knob for it to do that? I know there are 3 gain knobs in my amp... but I am just talking about left and right channels that don't match under the same knob...

PD... I am positive that its not an issue with the headunit because I tried several different sources and it still had the problem...

Thanx for your help

Set the DMM for AC Volts,

Test tone around 60Hz - that's the frequency of domestic 110vAC.
