The kickers should have come with wiring extensions with push clips already attached. The back of the speakers have small and large male ends the correspond with the wiring extensions for the female ends. Unless you have a wiring adapter to plug and play, you have to cut the factory wiring as close to the clip as possible. Should only be 2 wires to cut. Positive and negative. You need to check and make sure which wire is which. Flipping the wires incorrectly could damage your speakers. You'll need to strip the factory wires and crimp the wires provided from kicker. Again make sure you know which is the positive and negative lead. Crimp your wires together screw the speakers in and test em t make sure they work. Do one at a time! Lemme know if u need more guidance.
