Hey, I have a panasonic head unit (CQ 5110u) and I was wondering if anyone could help me figure out what one of the pigtailed RCA jacks do. I know the longer Pigtailed RCA is my sub output, but I have a shorted pigtailed RCA and I am wondering what those do. I am hoping that they are a aux input, but when I bought the head unit it was open box and the posted specs didn't have aux input. I can not locate any info for this unit and I am hoping somebody can tell me what they do.
P.S. I can't just go and try as I have a broken arm and I have no way to pull the head unit out with 1 hand
