I just tried to change them, and they are 4 inch, with 5.25 in the front. These lil brats are a b|tch to get to and tough to find a good pair of 4 inch speakers for less then 80 bucks. Pioneer makes a set but are kinda week compaired to the sony's 5.25's. The thing is that for mids and highs, a 4 inch with good tweeters work great. I had a problem as the box I keep in the back for the bass drowned out the stock speakers and all you hear is the beet when you sit in the back. I went to wallmart, grabbed a set of tweeters for 20 bucks, and installed with a 2.5 inch drill bit... I think.. anyway, it solved the problem and looks like this:
