The speakers are 4" as well but the plastic ring with the three mounting holes are too big to drop into the existing space. I don't think depth is an issue (I did not check carefully) but it looked like it would fit.
I guess I could sand down the plastic frame of the Alpines to make them fit but that's too much trouble and I normally have the speakers faded to the front anyway. I bought them because I thought they were a good deal and the magnets are very large compared to the original speakers so thought I would install them just for when I wanted to run all front & rears for a bit more volume.
