brianmission,

Scroll up to my previous post on this thread and hit the link for Winston Organ. Call them. Give them your dimensions and they will send you the right surround. I also refoamed my Infinity sub when I did my Missions. The sub was an odd size, so I had to cut and overlap the surround. Not a problem, and the sub sounds fine. It is not hard to do. Send me a PM if you have any more questions.
