			For the front it is modified.  I believe that no matter what way you go on the front, it is modified.  I found a few posts on how to modify the existing speaker bracket.  You have to completely destroy the speaker.  basically I used a dremel tool to cut away the old speaker front the bracket.  Then a put the new one in place, securing it with a little hot glue.    It wasn't too bad of a job.  Definitely worth it on the front speakers.
