I have a Saab 9000 CS 1996, and i have done some job on my soundsystem.
It´s nothing special but it sounds really good.
I have changed the original speakers to:
Frontsystem: DLS PS4A Proslim.
Rearsystem: DLS 960 Classic.
And in the trunk i have:
Subwoofer: MMats P3.0 15" in a sealed box for two subs, but i only have one.
AMP: Monacor Carpower 900WATT IGBT.
Well, im coming with some updates on my soundsystem soon.
I will upload more pics when i have the time for it.
