1997 X Speaker Wire Colors

I was Hoping someone could tell me what the color codes are for the speaker wires on my 1997 Explorer XLT. I am installing one of those RCA converters to the back of my stock HU and i need to know what wire controls what speaker before i can install my subwoofers. More specifically its a 1997 Ford Explorer XLT SOHC JBL Premium Surround System. Thanks, Any help is greatly apreciated!
