I have a 2002 s3 and the bose system is defo past its best.
When the stereo is playing I get a horrible tweeter crackle, which the louder it is the better it gets. That would be fine if I was 18 but im 29 and don't want to be blasting my tunes all the time.
The car has a double din headunit with tape and 6 disc changer which I believe is the symphony. Could it be the head unit? Its better on radio than it is on CD but still there.
Is there a way to test it? If I wanted to change the headunit, does anyone know the facia I would need, and iso lead? Ive searched it on here but gotten pretty confused.
Any help would be great.
