97 Avalon mod?

[JoeDaddy]

My Avalon only has 4 inch door speakers and would like to go larger. From what I have read on Toyota forms is I can easily go up to 5.25 in the front and 6.5 in the back. Anyone do this? How much better will the sound be? Thanks

Just upping the size won't have as much effect on the sound as sealing up and deadening your doors will :)
