I was looking the other day at the possibility of adding rear speakers to my 2006 MK2 Renault Clio Campus Sport due the mounting holes already being there for the speakers, just no connector. After looking online, apparently, if there are eights wires in the connector on the back of the radio, the wiring for the rear speakers is somewhere in the car. Is this correct and if so where are they normally located?
Here is a picture of the back of the radio (if it helps):
