Has anyone put 6.5 speakers in the rear panels (area that has cloth/leather next to back seats)? I went to a shop and they advised they would fit nicely. This is where they have the rear speakers on 6th gen Celicas from the factory and they sounded nice in my previous car. Has anyone installed them in this location? The pros... the cons? The factory two piece rear speakers on my 89 sound terrible as far as mid bass is concerned. Pics would be nice if anyone has done this.
