I think they are 3.5 inch speakers but again I made my own mounts. I found the speakers in the dash and doors were old and torn so I replaced them all. Sorry I couldn't be of more help. I would think they are pretty much standard for such a small speaker.

Hello

Sorry I did not see your reply.

I took off the rear speaker deck and noticed 1 speaker was torn.
So I was hoping to find drop in replacement speakers as I did not want to cut anything

Thanks

Hi! Well I bought a Chinese HU off ebay, DD. I upgraded the speakers in the dash and doors the ones I had were shot. I had the rear shelf storage (which I never used) so I added 6 speakers to the rear deck and swapped out the factory amp with a 996 factory 6 channel from a cabrio. I would be glad to give you what info I have but not sure what you are asking? are you looking to replace the speakers in the rear shelf? Do you have the factory speaker package? or are you looking to replace the dash/door speakers? I have a 99 Base and live in RI.

Hello MikeZ

I saw a post from you stating you upgraded your speakers with chinese drop in replacements
I have a 2001 base Boxster and the rear speakers are shot
any advice on how to find replacement speakers would be great

thanks

Mike
