OK I just bought a pioneer Premier 860 MP and all I got with it was the wireing harness that goes into the back of the radio, There are two other connector on the back that looks like something pluggs into the radio. there is also a spot where it looks like an aux cabel can plug in. I was wondering if anyone know where I could find out what all the connectors on the back of the raido are for because I want to hook up some subs and I dont see any RCA cabels like my other radio I had before. I also was wondering about the premier version, a kid I know said that premier was owned by pioneer and was actully not as good as the normal pioneers. I allways thought that it was an upgraded version that gave you extra features such as MP3.
