What are the stock speaker sizes for the front doors and the rear speakers on a 95 Legacy Wagon?

6 1/2 in. for the front and back.

Hi ! I have a 97 legacy sw and y have de tweeter+speaker version. Do you know the depth of the speakers ? I'm affraid that when I change them the will touch the window.

This information isn't correct.  

 

I have a 95 Legacy L Sedan and the rear deck speakers are not 6.5 - they measure 6.25 and require an adapter to fit 6.5.  Learned this the hard way...  6.5 will not fit.

Wagon doesn't have speakers in the rear deck. (There is no deck)

Wagon only has speakers in the doors and 6.5" speakers fit perfectly.

 

Depending on the speaker design you may or may not need an adapter, but most 6.5" speakers come with adapters to fit them into a 6.25" mount.

In my 93 wagon the rear speakers are on top of the strut towers and are 6.5's.
