Thanks for all the replies so far guys. Now I might be mistaken but I do not think the kenwoods are very deep speakers. I think with their dual mag technology their magnets are not as huge. Now it could be because I am looking at 5.25s but they do look pretty small. And also these dual mag speakers are the lightest speakers I have ever held so basically what I am saying is that I do not think that they will be hard to fit in. I dunno like I said this is my first system and I am trying to do it right the first time!!!
