Wire colors for rear speakers

[cuzican]

i'm fixing to hook up a line converter to run an amp and subs with my factory head-unit. I was needed to know what colors the rear speaker wires are at the back of the HU so I know which one to splice into. Thanks

sorry, it's a 00 ls v8 with the 6-disc in the glove-box and it had the factory sub-box in the rear deck but I took it out.
