what are the speaker wire colors for 2006 cobalt?

Answer 1

They still follow the GM standard:

LF+ tan
LF- gray
RF+ light green
RF- dark green

LR+ brown
LR- yellow
RR+ dark blue
RR- light blue

Note that if you're looking for them behind the radio, some of the same colors may be used on other wires. The speaker wires should be placed side-by-side for each speaker.

Also, if you're replacing the factory radio, I highly recommend buying a wire harness adapter instead of cutting off the factory plug.
