I have a 2020 civic lx and tried to install 6x9s in the rear deck. I cant figure out which wire is positive and negative. The driver side speaker has a blue and white cable and the passenger side has a brown and yellow cable. Does any one know which ones positive and negative?

I have my rear speakers plugged that way but im not getting sound from any of the speakers now.

could it be that the terminal is touching the body of the car? lemme know if im making any sense.

If any part of the metal terminal is touching the metal of the body then you will get no sound.
