Hi. I am installing Subwoofer in my car listed above GT Convertible. I am keeping the OEM head unit, so I am having to install a line out converter for the RCA plugs. My car has the Shaker OEM stereo system, and I was wondering what the color of the wires going to rear speakers are. I am going to have to splice into them for the LOC or tear all the panels off of the driver's side to get access to the driver's side rear speaker. Splicing might be better because the sub is being installed on the passenger side anyway. Thank you

The color of the wires for the rear speakers in your 2015 Ford Mustang GT Convertible with the Shaker OEM stereo system may vary, but typically the wire colors for rear speakers in a car are in the radio wiring diagrams below.

Here is a guide to help you test the connections:

It's important to note that these color codes are not standardized and may vary depending on the car make and model. I would recommend checking a wiring diagram or using a voltage tester to confirm the correct wires to splice into before making any connections. Let me know if you need anything else.
