Rear Speakers Location: Side Panels
Left Rear Speaker Wire (+): Black
Left Rear Speaker Wire (-): Yellow
Right Rear Speaker Wire (+): Red

-----------------
But if after connecting this way,your radio is not operating then its possible that fault is in radio itself.
To confirm this,try this test.
Use a 12 volt test light to see if there is power between the gray and brown wires when the key is on. If there is power there, you may have got hold of a bad radio.
check to see if there is power at the fuse. If there is power at the fuse, run a new wire from the fuse box. If no power at the fuse, either the fuse box is bad or the feed from the ignition switch is bad.

This details will help you.
