OK thanks. Saw that for the Sub but didn't see it for the Aux In. Must have missed it. The menu could be more intuitive. Wasn't overly concerned with exact matching, but did want more volume at a lower volume setting less near the max setting.
What is the minimum input voltage to drive the 'Aux In' on a Sony DSXA415BT? Every device I use the sound level is low. Have to turn the volume to 26 plus to get same output as 16 on the Tuner.
