There is a gain adjustment on the GMOS-04, it is located on the side of the little box, actually there are 2 gain pots, one for the chimes, I believe that one is on the end by one of the connectors, and the other is for your system. Play with it until you like the sound. That is all.
Thats what I was saying, I can't turn the gain up enough to get rid of the distortion. I went ahead and wired it in directly, I leave for work in a few minutes, well see if it drained the battery too much my wiring the switched lead into the constant.
