Bill - First off, thanks for the great write up with pictures. I wish more people would post pictures of their custom installs. Have you identified a replacement for the dash midranges?

I never heard Diamond speakers play before but I am willing to give them a try. When I search the internet I only see D362.5. I would think that they are pretty much the same as the D362.
