I just replaced my front speakers this weekend with brand new original parts. The tweeter has a plug that plugs into the door speaker. If yours is different then somebody messed something up. (EDIT: Also, mine is a 97, your 00 might be different)
I looked for stock (AC Delco) for easy install. I didn't want to worry about splicing and different connectors.
Here is a link to where I got my speakers from. Be patient, as this website can be difficult to navigate. ACDelco and Motorcraft Auto Parts OE Parts Headquarters -
Hope this helps you out![]()
