Chevy Equinox Speaker Wire colors.

[inlovewithmychevy]

I have a new 2006 equinox with a factory radio setup. I'm trying to determine which wires from the raido are which, so I can hook up an amplifier.

I need to know what color pairs go to which speakers. The rear speakers specifically. Thanks in advance.
