There are no factory two-way speakers in that car, hence the OEM component setup. You have two 6.75" midranges in the doors, two tweeters in the doors (I don't know what their size is - they're proprietary), two 6.75" subwoofers in the sail panels, two 4" midranges in the hatch panels, and two more tweeters in the hatch panels. If you use a traditional coaxial speaker in the doors to replace the midranges, you may find your sound imaging in the front is too "bright" (that was my experience). If you are good with a soldering iron, you could remove the capacitors and inductors from the OEM speaker chassis and use them with the replacement speakers. You will preserve the factory sound imaging and not have too much treble.
