Is it necessary to remove the midrange/tweeter pedestals?
I removed the midrange/tweeter pedestals because the midranges were damaged, and I only intended to use the 6x9s as subwoofers anyway. Depending on the type of 6×9 you get and how your adapter plates are constructed, you may have to remove the pedestals as there may be some interference (some pedestals stick up out of the 6×9 a little bit and may contact the edges of the adapter plate’s smaller opening).
