Rear Speaker Wires

Which speaker wire is negative on the rear speakers. One side has brown and yellow, the other has a light blue and a darker blue?

Thanx

take a look at the old GM speaker harness, one wire input has an A that is the positive, the other has a B that is the negative. I want to say the lighter color is always the positive but I am not sure. Please wait until I verify by checking my car.

Here is the color schematic for the rear speakers. Hope you get to read this. I apologise for not giving you the information quickly.

brown = left rear +
yellow = left rear -

Dark green = Right front -
Light green = Right front +

Tan = Left Front +
Gray = Left Front -

Light Blue = Right Rear -
dark Blue = Right Rear +


Hope this helps you. Once again sorry for being so late with this information.
