Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. I would access wires behind radio because its going to be harder to run wires through door jams. Here are wire colors for speakers and instructions to remove radio. let me know if you have any questions. Thanks.
Left rear - yellow
Left rear + brown
Right rear- light blue
right rear + dark blue
Yes you will need to disconnect it but you should be fine because it will still be programmed for your vehicle. Let me know if you have any questions, thanks.
Here are also intructions to remove door panel if you want to stick with orignal plan. Let me know if you have questions, thanks.
I was curious...In a previous post pertaining to speaker wire colors...you have the yellow wire as being the left rear negative. Yellow is also listed (on multiple sites) as being the switched power wire from the ignition....
