Well, i'm considering replacing the speakers in my 03 tib. I have the infinity sound system. I am planning on getting components up front and some good 2-ways in the back. I know the tweeters will need some custom work, but for the speakers themselves...do any just fit? I mean without adapters or mdf rings? I would really love to pull the panel, pop the old speaker out, put the new one in and put it all back togeather. What are some good options that have been used with little to no modification of the brackets and such? Please post model #'s and sizes if you happen to know. Thanks!
