So, I just bought a 03 Grand Am. I would like to put speakers into it within the next few weeks.

The door panel looks like this (From a 99 grand am but still the same concept)
Anyway. The tweeter is what I an asking about. I was told I need to make a custom mount for the tweeter. How can I keep the stock look of the tweeter but still fit one in there?
Anyone that has done a grand am please feel free to chime in.
