Just brought a pair of Infinity 6.5's for the back doors of my 2002 Maxima (non Bose). Took the door panels off and discovered that the wires on each side are not only 4 different colors but there is no "+" or "-" symbol on the factory speakers.

Can someone tell me what color goes to what terminal?

On the right side(passenger) the wires are red and blue.
On the left side (driver) green and black/yellow stripe.

thanks.
