Sounds in my Aurora

Hey guys i was woundering if anyone got sounds in their Aurora, because i'm going to put some pretty soon and i need to buy a dash kit for the head unit, i'm planning to put a pioneer DEH-p6600 so if you know what kind of kit i should buy let me know. Also, the guy that had the car before had some kenwood cd player and when i took out the stock delco radio i found some of the wire harness that goes in the rear part of a head unit loose and also they did something to the antenna because i only have a TV antenna loose too that says kenwood on so i don't really know what kind of cd player the guy had before but i really need some help here and i don't want to take it to a sound shop because they charge you a lot of money and sometimes they don't treat the car right so i rather do it myself i'll take some pics of it so you guys could see what i'm talking about, because is kinda hard to explain and understand what i'm trying to say.
