What are the speaker sizes in a 2007 Corolla?

The 2007 Corolla has a couple of different speakers and sizes in it. The front and rear door subwoofer is A6-3/4" size speaker. These are the ones that are in the panels of the door. In the back corners of the vehicle You will find 6x9" size speakers. These are the ones behind the back headrests. Finally, the speakers that are in the middle of the dash are tweeter in size. These are standard size tweeters, as in they are the same in any car, hence they don't have actual measurements. These are the speakers for the base trim on this car. Other trims may have had better speakers, but due to the age, anything You buy now will likely be better than the old standard.
