Equalizer adjustment...
If I were you I would just tune it the way you like it.
The best way to learn is to push all the slides down and push each one up one by one to hear what each one is doing. Then just play around with it to customize it to your liking.
- only thing i really adjust for songs is bass... some go over and dround it out (sounds crappy then) so i have to turn it down and some i have to turn it up for cuase there isn't enough. Asking how others have theirs set might not help much as you might not like the way it will sound.
Just be very careful on the bass side as it seems too easy to blow the sail panel speakers in these cars.
