I found a good audio setting awhile back in the forum here. Let me see if I can find it if not I'll goo out and see where my stuff is set. It's still not magical but it got rid of allot of the unwanted crap sound you usually get from ricers with their full bass vibrations at intersections.
here ya go. Bare in mind this is for what I listen to..Barry Manalow, Justin Beiber....ok I'm kiddin but it sounds good with anything from Rock (Metallica'ish) to Industrial (NIN) to stuff like the RHCP and Drop Kick Murphy's....Also my Bass is +4 and treb +1
