Ford Focus - Rear speakers not working - K21000

Speakers never worked with original head unit. Now have a new Alpine unit and they still don't work. Not sure if the grills in the rear door cards are just there for other models which have speakers. I would have thought mine would have speakers as it is the highest spec Focus for the year. It's a 2005 1.6 ghia 5 door. Hopefully someone out there has this model and can confirm if it has rear speakers or not.

Not without removing the door cards, which I don't really want to do.

The car when it was new had 6 speakers 4 in the front a two in the rear .Remove the radio and measure the resistance of the individual on the iso speaker plug to see if they are working or not.
