So is the input going into the RCA input side of the processor or into the hi level side? I was under the impression that the amp used hi level inputs out of the deck. My reason of thinking this is that the Jeeps without infinity systems use the same plug to provide audio through the head unit. With the infinity system that same plug goes into the amp. Am I looking at something the wrong way here?

 

i have had to ask the guys who installed it, and they have advised it has taken the input onto the high side to clean the sound down correctly and flatten out the peaks and troughs
