all my speakers are blown except the front passenger. so i went to Best Buy and this is what they tell me:
4 4" polk audio speaker all around.
polk audio amp
polk in-box subwoofer.
installed for $800. (that includes installion charge and wiring)

should i do this or is there a better way? how do find out what audio system my car has?

As far as I know the following list is the only thing that fits without
the door panels or the vapor barrior being hacked. The depth for
the sedan is 50mm and the depth for the coupe is less there are only 4 speakers that I know of that fit in the coupe . Focals, Jehnerts, BSW and the OEM's
The only 4 inch that Polk makes are coax.

I would learn the specs of the car if they can not describe it they don't know what
there doing . Ask them about the connection between the amp and head unit see
if they can identify the fiberoptic connection. Ask them how they are going to handle
that.

Also you have to keep the orignal amp with that because of the fiberoptic connection
between the Head Unit and AMp. You could tap the speaker outs to run another
amp. You should learn more about what you have before you allow them to butcher
your car.

I wouldn't take your 50k car to Best Buy.

yes, i been reading info on the car audio system for now. i just stop at a local bestbuy to get a estimate, the car tech talk about the fiberoptic connection and said it might better to change the whole audio setup, thats when he gave me a estimate of $800 for everything.
i think im going to just replace the speakers with the one everyone here is doing. its only the 4" speakers(front & rear) that are damage..i think.

They sell a kit that allows you to self install.
Google Bavarian Sound Works.
There are many other choices but they get pricy pretty fast.

The Focals in my E92 are magic! Love the sound. But they JUST barely fit...they had to be fitted PERFECTLY in order to clear the window when closed. Very tight fit.

From Technic, of course! JK, just PM him, he's one of the resident experts here. He makes them for all kinds of connections you need to upgrade the audio in all the various systems.
