Why would left front speaker wiring be down low in a yellow push connector on the left b pillar by the drivers seat? Or maybe that is "light green" and not speaker wiring? Trying to tap into rear speakers eith amp wire or front don't care at this point... I have a 28w rms amp in my android head unit(tda7851) but I just got components for the rear with 3.5 inch tweeters that I want to put in the holes next to the back seat rest. What is the easiest way to tap in?
