alright. the amp does have an amp 1 amp 2 setup with separate gains on each. put fronts on amp 1 back on amp 2 and turn gain down on amp 1. With running different power to front and back is that going to sound bad or should i adjust the gains on both to match? also will the shrill "sss" sound get worse?

sorry for all the questions still kinda new to all this audio stuff.
