It sall hooked up and Ive started tuning and WOW what a difference! My only sort of issue is that the input from the Zen is very low . I have the input cranked almost all of the way up in the Audio Control DSP APP and my outputs turned up and it gets plenty loud just under full volume. Would it matter if I hooked up more than one output from the ZEN to the amp? Currently I have outputs 1-2 from ZEN (right front/left front) into Audiocontrol Front (1/2) and i am getting a full range signal but it is very low. I cant imagine more inputs would do anything different as they are line level. Im going to try sending the rear doors from the ZEN out to the Audiocontrol amp and see if there is a difference. I am unable to get it to clip when setting up with pink noise source and truck volume maxed out with input maxed out in the DSP.
Have you adjusted the output level settings in the zen?
