So I have searched and searched and all I could ever find was the wrong description of color for rear speakers wires in a FD. I wanted to make a post just in case anyone else is ever in the same situations as I am:

Incorrect:
Left Rear Speaker Positive Wire (+): Blue/White
Left Rear Speaker Negative Wire (-): Blue/Green
Right Rear Speaker Positive Wire (+): Blue/Red
Right Rear Speaker Negative Wire (-): Blue/Green

Correct:
Left Rear Positive Wire (+): Yellow & Green
Left Rear Negative Wire (-): Yellow & Blue
Right Rear Positive Wire (+): White & Blue
Right Rear Negative Wire (-): Blue & Yellow
