I can't remember if the windows on the back doors of the STI go down all the way or not. I never paid attention. Mine don't. I know on most cars that the back windows only go down a certain depth for child protection or whatever they call it. But i thought i glanced back once and saw mine were all the way down. The reason i am asking this is because i had my stereo installed and i wanted to know if the windows were hitting the speakers or if they were only supposed to go down that far. Somebody wanna check their STI for me and let me know. Peace!!
