Just letting you know i just completed changing my front and rear speaker (Infinity Mygig) I chose pioneer TS-A1672R 61/2. Although they are 6 1/2 inch they did not fit the factory boxes in the dash or in the tower. They were just a little to small, I was however able to make them ok with some buttle tape and screws and washers. The factory dash and rear covers almost make the speakers invisible to theft. It was a very worth wile upgrade, However next time I would have chosen a speaker with a larger mounting plate.
