Brava rear speaker size & improving audio

[Markus]

(I'm sure this can be found in the forum archives, but every time I do a search I get an error...)

I'm thinking of installing rear speakers in my Brava, but just to make sure: is the right size to get 13 cm for the back? When I had my stereo installed someone said the rear speakers should be 10 cm, so which one is it?

Also, is there any (relatively cheap) way of improving the audio in the Brava? Whenever I play a tune with lots of base in it my front doors rattle like hell - is this because the factory fitted speakers are crap or is it simply the acoustics of the door? Will I make the situation better by fitting new speakers?

Thanks!

13cm in the rear, i had this with my standard speakers, never heard any complaints from anyone after upgrading so i'd say it be the speakers not the doors
