I don't believe this is possible. Check my other posts to see how to make a 18 system better. Quite a project. Changing the speakers only will increase white noise and will not even sound better.
Just took off my spoiler. Going to plasti-dip the MP Concepts GT500 style spoiler and mount it. The plasti-dip is still perfect. There is some wax on it on the top from careless waxing. The wax is the only imperfection. I have not attempted to remove the wax.
There are Sync 3 forums that can show you how to do advanced software changes like revert to earlier versions of Sync and stuff. You might look them up.
