Guys I am adding 8” speakers to the rear roll bars of my 2018 jk. I have got a waterproof amp and Plan to use the factory head unit. I have purchased a pac loc and was hoping to simple tap into the speakers so i don’t have to pull out the head unit. I would think the rear would be easier to get both left and right speakers, but I don’t know where they run let or right side or wire colors. Please help or give advice

I know on the 2016s the black wire is positive and white is negative not sure about the wire colors on an '18
