I am looking to wire up an AMP with a sub. I have pulled the carpet back a bit on the driver side. Apparently the rear speaker wire colors are light blue and dark blue. yellow and brown. Now where it gets confusing is there is 2 yellow wires in the mass of wires and not sure if they are both the same, same thing for the light blue wire. I guess in short, are they both the same or do i have the colors completely wrong? And are both left and right in that harness or is there another bunch of wires on the right side to?
Any help would be great.
Thanks.

 

On mine they were twisted together loosely for each speaker. you need to go under the passenger side carpet to get the other speaker.

 

Just pop the head unit out. It's only 4 screws.
