Do not go Bose! If all you want to do is upgrade the dash speakers replace with some herts or Alpine coaxial, you can either cut up the old speaker to diy a braket or order mout for I think $30 from CAI audio.

You could go focal, depends on what you want to spend.

I did complete upgrade did 3 way components amp and finishing a subwoofer mod using bose footwell sub from 996 cabriolet. Pulled the bose and installed 8” pioneer.

I digress, easy to open the dash speaker and check type. Will hold up to a 4” easiest is use a coax. Watch the depth.
