I've just installed and replaced all 4 speakers with Polk Audio DB series and mounting them similar to the method here. Everything playing well and I retained the factory plug. The important question is does polarity matter? If polarity is reversed , would the speakers still play? How do you test for the polarity?
Easiest way, look at speakers! When base hits etc if speaker moves outward your good. If speaker goes inwards, flip the hooks ups
