I am trying to install the EMG PJX pickups in a bass of mine. The way I wired it was similar to the JX style with volume/volume/active tone. The neck pickup went into the 1st volume, and from there, a wire from the first volume went into the second volume along with the bridge pickup. Then a wire went from the second volume into the tone, along with the output jack and a red wire for the voltage. When I plug it in, I get extremely low output (like have to my amp on full to hear barely anything at all) and, from what I can hear, it is distorted. I am not experienced with active wiring, but the only thing I had to solder was to the output jack. There is not wire going to the bridge for grounding, if that matters.
