2003 sirion speaker size

Hey champions wondering if someone can point me in the right direction as google don’t know nothing. I am looking at upgrading the speakers in my 2003 sirion and wondering if anyone knows what fit and if the same size will fit in the back?

I upgraded to 6.5 splits for the front of my Sirion. I think I had to put a spacer to make it work and also cut into the plastic of the door trim. But they fit behind the stock speaker opening in the trim and the tweeters I put in the top of the door. In the back I believe I put in 5.25 speakers and just bolted them in.
It has been 8 years since I did it, so my memory might be spotty.
