hi!
I've been looking around for the week or so and can not find the certain answer.
I find the factory fitted audio system just embarrassing ( non Bose) and I want to upgrade it.
One of main things needed upgrading are Speakers
I really do not want to start tearing door panels off in this cold just to find out what size of speakers needed.

If anybody did upgrade of speakers and knows for sure what size of speakers is needed for the front and what size for the rear?
is it 6-1/2" (16.5cm) 5-1/4" (13cm)?
are there any speakers adapters needed ? I mean for the speakers case not wiring's

Any kind of help would be greatly appreciated

thanks
