As I've been doing my research here and on a couple Mustang forums, I've come to the realization that the 6.5s I was planning on using (either Daytons or Silverflutes) may be too deep. Based on what I've read, 2.75" is about the max depth for my door speakers. It seems like everything I've found is either too deep or much more expensive than the two brands I mentioned above. Can anyone recommend some that'll work? I may be able to squeeze a 1/4" spacer in there and make one of these, but it doesn't sound promising. Those that have done the 2.75" deep speakers had to reuse the factory spacers and it sounds like there's no room between the speakers and door panels.
