[QUOTE="Alrojoca, post: 7918611, member: 638714"] I have a question guys, hope to clear my thoughts with your help. I have a case where I have 5 volts RCAs for the head unit. The amp voltage gains goes from 6 V minimum Counter clockwise (from left) to something like 2.5 mv max (0.25 v ) or close turning the dial to the right. To set the gains with 3/4 volume using a wavetek digital voltmeter I had to go clockwise ( turn dial to the right) near the max. Does this sound right? That basically tells me, if the HU has 5 volts, instead of turning the gains low on the amp , they have to be turned high. Meaning high equals less voltage on the amp? Less V on the amp equals more volume? Again to get to 29V for a 220w sub at 3/4 vol, using a 5 volt rca HU I had to twist the dial to the right near the end or max close less than 1 volt. Does this sound right or make sense? Thanks [/QUOTE]
