Black & Brown MEDIUM = Negative front left door speaker Black & Red MEDIUM = Positive front left door speaker
Blue & Brown THICKEST = Negative front right kick panel speaker Blue & Red THICKEST = Positive front right kick panel speaker
Blue & Brown MEDIUM = Negative front right door speaker Blue & Red MEDIUM = Positive front right door speaker
