just to clarify though, you can add the tweeter to a non-mach panel by cutting the bottom of the tweeter enclosure off. But if you get a mach door panel and do not have the tweeter it will look a little funky where the tweeter should go like something is missing. So your fine no matter what if you get a non-mach door panel but if you get a mach panel you will need the tweeter pod to fill the hole.
