Sorry if this has been covered extensively on this board, but I am trying to find out what is necessary to put in a JVC headunit into a 2004 SE non-JBL system. I'm not the owner..i'm trying to buy as a gift adapters necessary to get the JVC hooked into the stock speakers. I already bought the faceplate, brackets, and ipod cable and I'm not sure what is easiest without having to cut and splice existing harness. Thanks in advanced.
