I am having issues trying to upgrade my speakers in my 2014 JKU. I am replacing the rear sound bar speakers with 6 1/2" Kenwood 3-way coaxial speakers.
The 6 1/2" I bought are quite noticeably smaller than the stock ones and can't be mounted because the speaker hole is too big. There's not enough to screw into. How can two speakers be advertised as the same size but not fit the same hole?
I'm so confused. And frustrated.
