I can confirm the rear speakers do indeed run into the conduit located in the upper right (when viewed from the rear). Mine have been cut but it will be a simple job to solder them together.
The routing of the 8 pin DIN wire follows the same path but I am still tracing it. It may duck under the centre console instead of the conduit down the passenger side floor pan.
