Car Speaker Size

how positive are you? I only ask to avoid wasting money when I try to upgrade them. I had trouble getting the rear door panel off to see for myself. thanks a lot for your answer =)

That is the size Crutchfield lists for both of the factory stereos.

ha crutchfield says 4s but they aren't 4s better count on making an adapter plate they more like 5 1/4

Owner of 06 subaru impreza outback. The rear speakers are 4", confirmed. You will need to cut a larger hole if you want 5 1/4 to fit.

and good luck without some adapters casue a 4 will actually fall in the whole casue of the factory speaker built into a surround
