I realize that the Gen5s and Gen6s are different but, at least with the Gen5s, an adapter was needed to install a replacement for the factory door speakers. I assume this to be true for the Gen6s. As for the tweets in the top of the dash, they look like a complete bitch to get out and replace. Makes you want to intentionally blow them, buy replacements, take the car in under warranty for the blown speakers and tell them to install your aftermarket speakers instead.
We don't necessarily have to use those tweets or use that tweet location though. An aftermarket tweet could be mounted elsewhere or you could just use a coaxial speaker instead of a component speaker. There are options available to get around messing with the dash tweets.
