system install advice - audi 80

[lejaybo]

Hello guys

need some advice on my potential system for my audi 80 saloon

so i don't want to cut any holes or build any pods, i;m trying to keep the interior standard.

so the orignal audi system has
4inch drivers on the dashboard and
6inch components in the rear shelf (mid bas + sperate)

i know the stereo image won't be brilliant but i do want the system to sound better than it does now,



my plan is to use all the standard speaker locations and add a subwoofer

1. notsure what speaker make to go for,

2. notsure what freq to set the x-over between the speakers & sub

3. was thinking of using a pair on 8inch subs
