So I changed the rear deck speakers of my 2006 Grand Prix base (3800 v6) and believe me it was a pain! I did it without removing the back seats just fold down. So I had a friend help me run lines then installed speakers. We put everything back but then noticed that we forgot to screw in the speakers! (their drop ins from the trunk). Would it be okay if I leave them as is or is it necessary to remove everything up and screw in the speakers?
Yes, when I access the trunk and i push the speaker up they feel lose but their stopped by the deck.
thanks.
