Now I'm unsure whether I've got the polarity the same as the rear speakers, since I feel I can't trust this document now...
Has anyone else seen this?
What is the correct wiring color & polarity for a 2003 Impreza - Canadian model?
That pinout shows the wire colors of the harness that plugs into the radio. In many models/years the wires change colors by the time they reach the speakers.

Complicating matters is that on some of Subaru's wiring diagrams the wire colors at the speakers are drawn backwards or wrong from reality.

See this thread for colors in the 2002:
Factory speaker wire color codes
Those colors may be the same in the 2003.

Usually, the larger pin at the speaker is +. But a quick and easy way to tell would be to unplug the radio and speaker, and use a battery and voltmeter to check.

Please let us know if your 2003 is the same as the above chart.
