Basically you ignore factory wiring and remove the factory tweeter and 3.5" midrange and factory woofer, and remove the factory x-overs. The component speakers come with their own x-overs and are already set properly. The tweeters and woofers should fit in the factory locations just fine, iirc.

The crossover that comes with the speakers routes the correct frequencies to the proper speaker: the tweeter highs go to the tweeter and the other frequencies go to the woofer. It's at the external amp level that you use the amp's built in high-pass and lo-pass filters to channel the subwoofer frequencies only to the sub (set the low-pass on the sub channel and the high pass on the speaker channels).
