Disconnect the factory ones and chop the connectors off the ends, strip about 1" of flux off of each wire, then thread the wire through the terminal on the speaker and TWIST the wire together back on itself VERY VERY tightly against the speakers terminal, then solder them to the terminal.
wires are...
Left Rear ~ gray/white = negative, & blue/yellow = Positive
Right Rear ~ Brown/white = negative, & red/yellow = Positive
If you have an uprated head unit and are uprating the speakers, then its best to take off some of your interior trim and tie the new uprated (thicker) speaker wire to the end of the factory wire, then feed it through to the stereo, are trying the wires included with the speakers will generally be heavier duty and higher surface area than the factory wires. Trying to run higher wattage speakers via the stock wiring will result in quality loss. Speakers are generators too you know!
Hope this helps all you EK9'ers and EK owners out there. Any mroe info needed just ask
