Hi!
I want to purchase new speakers for
3-door A3.
What speakers size must I look for
to fit them at:
1. front doors(tweeter and midrange).
2. rear side panel (two-way speakers)

And what type of speakers should I use best (brand) to make it go hard?
Thanks a lot!

front 13 cm rear 17 cm
you will need a speaker adaptor depending on speaker make.....

front 10cm(4"), rear16.5cm(6.5"),go for very good (expens)AVI at front,rear- BOSTON ACUSTIC.

In the front, there are 13cm spekers, not 10cm!!! In the left side of the boot, there is a 16cm subwoofer from Nokia, this one need also replacement. Just visit some car-hifi store in your near. Don't buy Sony and other cheap marks, or you'll be very unhappy. Can recommend you something from ACR group (EmPhaser, Rodek), Rockford Fosgade, Focal, atc.. If you need some advice, just mail me at paja@ahc.cz.

ive found infinity or mb quart speakers the best all round performers
