Just found out how shallow the rear side is...the speakers I bought require too much space to mount and the right size spacer will cause issues with the arm rest panels....anyone found 6.5s that are shallow enough for this area?

just use the old speakers as a spacer if you need more room

Boston Acoustics SX65's fit fine for me.
What are you trying to fit?

thanks for the help! i ended up using the speakers from the front doors and turned them into spacers to fit these speakers in (i wanted to keep the rear speakers just in case i wasn't able to make it work)....its not the prettiest thing but it worked and certainly sounds better than the Bose!
