I dunno.. I replaced my head unit but I've never looked at the speakers.

Try searching in the "stereo, communications, and electrical" forum - and if you can't find anything, maybe repost this question there where people are more likely to see it.

ETA: From a brief search, it looks like the 6-speaker '00 SE has 6x9 speakers in the rear and then a 6.5" round speaker plus a 1" tweeter in each front door... but I only looked at like one thread. I'd do a bit more research if I were you - plus make sure you get the right impedance speakers. I didn't look to see if they're supposed to be 2 or 4 ohm... but I know that info is availabe on here.
