I have a Sony cdx c90 connected to a Audiocontrol 3xs. I have had the deck for a few years, but the crossover is new to my system. When i have my deck turned all the way up i does not turn on the signal maxamized light on the 3xs. Then with my deck at full volume I turn the output adjustment all the way up on the 3xs, which only gets the 2v light to turn on. I thought that my deck was 4v out, so i expected more output than 2v. Should the 5v light be coming on with this equipment and this setup? I'm wondering if there is something wrong with the output of my deck.

The input maxamized led is supposed to come on when the deck is within 3db of clipping. I turn my deck all the way up and it doesn't come on. Does this mean that at full volume my deck isn't clipping?
