Hello Forum, I never thought it would be possible for me to be interested in Car-Hifi, but the sound system in the 9-3 (I) made it in less than a week: It just sounds grütze There were even the serial speakers in my 96 Corolla significantly better. More balanced sound bill, more pressure and more abundance, but more transparency. The Saab system sounds thin and somehow unharmonious. Question therefore: What is so bad about the built-in system, the radio or the speakers? Differently asked: Does it bring something, simply to install other loudspeakers (front, possibly only above?), or is a power amplifier mandatory? Or even another radio that I would like to avoid … Would be grateful about a few tips, would also like to know about information about the speaker exchange, if useful (type, size – am an absolute layman in this regard) Merci Seb.
