I just installed a new Eclipse CD5435. The non-fader does not have the same effect as my old head unit (Eclipse 54110). On my old unit I could turn the non-fader to 0 and essentilly mute the sub or turn it to 15 for full on glory...anyway, the new head unit (CD5435) non-fader controls are from 0 to 6 and there does not seam to be much difference between 0 to 6. Any thoughts....? I have turned the gain down on my amp running to my subs. Anyone have any comments abouts this head unit???
