ok i know search first but every time i do search i get a different answer. So what are the speaker sizes for the 2001 i30? the front and rear door speakers. Some are saying 6" and some 6 1/2. i have even seen 5". So it need a final answer

 

All 6 and 1/2. (or 6 and 3/4 either one)

 

i think the back is 5.25 because of the bose system no? I forgot what my installer put in mine...I can check though

 

6.5 front, 5.5 rear.

 

I have heard of there being 5.25 in some cars, I have 6.5 all the way around, not quite sure why Bose would make it smaller than it needed to be.
