Eu-700s drop right in with plenty of space around them, so you should be able to fit just about anything that's a 6.5"....the only thing you have to watch out for is the window track, but this isn't really an issue unless you put in something larger(dia.) that would require minor cutting. The 'problem' with putting speakers in is there isn't really a way to make a secure connection without some sort of spacer(such as a modified OEM unit.)
