Usually on Pioneer head units, the pre-outs in the back, say there are two sets, will designate front preout and rear preout. if you plug into them it will just kinda play interference. Those are used for output to front/rear amps.

The best way to work with a Pioneer deck is using the IP Bus.

hmmm… that’s terriffic if talking about the pre-outs. issue here is with the aux input which i assume is a “headphone” jack on the rear of the headunit. try the cable first then do the unit
