Which wires are for rear speakers??

[komichal]

When I was playing around (for my Yaris 2007 hatchback) with that I found out the colors below:

Left Rear Speaker Positive Wire (+): Black
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Red
Right Rear Speaker Negative Wire (-): White

Those two thin ones, white in the very bottom and red right above it.

The question is how to get them through to the door, because they end here, unfortunately.
