My amp doesn't take SPDIF, so I'm bound to analog. I don't want to add another digital-analog component into my car either.
Anyway, I was able to improve the signal by making changes to my software: I now divide the volume range into 3 parts, which I call soft, hard main, and hard F/R:
hard F/R range: ( 0db -> -10db) software is at full volume, sub is at full volume, front and rears are adjusted as one.
hard main range: ( -10db -> -35db) using system main volume control here (software still at full volume, but all 4.1 speakers are adjusted as one).
soft range: (-35db -> -70db) at this point I'm using the software APIs (audio, video, dvd) to make volume adjustements, since below -35db the hardware volume controls don't work properly.
Also, I have a bass boost dial hooked up into my amp, so that I can make quick adjustments based on the music I listen to.
So... with this I'm relatively happy with the bass output, but in the next few months I will give an external usb audigy a shot, too. Theoretically this should clean up the signal.
