This is an easy task if the wires are already run and all you are doing is replacing the factory speakers. Remove the grilles, or covers off of the speakers. Unscrew the speaker it self and disconnect the wires. Most of the connections will be ‘spade’ type connectors, but sometimes they will have plugs that will need to be taken apart carefully. Attach the wires to the new speakers, and screw them in place. Replace the grille and enjoy the tunes.
