I have a 2010 Ford Transit Connect factory radio with CD player (6000 series). The radio has 2 front door speakers only. I would like to possibly add rear speakers and wire them into the factory radio. My dilema is this, I understand that the factiory radio has only 2 outputs for the front speakers, rear speakers were not available till 2012 I think. 1) Has anyone added rear speakers to their Connect, after removing the headliner there are 3 speaker openings. 2) Which opening do the speakers go into (1, 2 or 3 with 1 being towrds the rear and 3 being towards the front) 3) Can you wire the rear speakers into the front speakers or do I need to upgrade to an aftermarket radio with 4 outputs 4) Has anyone installed a 2012 Ford Factory radio with success (Ford Fusion or Milan style). I know I have many questions. Any and all assistance would be greatly appreciated as I would like to have rear speakers with minimal work if possible.
