I recently got a 2008 Mazda3, 5 speed manual transmission, and I've noticed that once in a while, like when I take a hard turn, or sometimes put the clutch in, or downshift, or other random occurrences, the music I'm playing, whether it be from a CD or Media like my iPhone, randomly diminishes to just the treble end of the music. Like the bottom half of the sound has just disappeared. It's not just like dubstep or whatever, just any music at all. I'm not complaining that my bass is too low, there's a setting to adjust that. I mean it is literally like the sound is cut in half. It is not until I hit volume up or down does it return, only to be diminished again shortly after, randomly, without my doing. Does anyone know why this is? Do I need a new radio center unit thing? That would really stink because they're expensive and I just don't want to go through all that, or is there something in the car's manual I don't know of with some setting that random reduces what the output of the music is? I've tried the ALC feature or whatever it is, level 1, 2, and 3, and off, and it makes no difference. The audio still does this. Has anyone ever had this problem before? Any fixes?
