Hi,

I'm looking into replacing the speakers in my Audi A3. I don't have the Bose stereo, I have the Audi Concert. I have searched online and get different results when it comes to speaker sizes. I search results indicated sizes from 5.25 - 6.5. Can anyone who have replaced their speakers tell me what sized you used. Also if possible tell me the place that did the work. Also did anyone install and create a custom subwoofer in the back. if so let me know where I can go in the GTA to do so.

Thanks,

 

5.25 & 6.5 can sometimes share the same space.
