There's no "universal" tuning as the car itself affects the frequency response. This is also the reason why you can have the exact same setup in a car but once you throw it in another car, it can sound vastly different.

I have no idea what Q1W,Q2W,Q1N,Q2N means.

The general "curve" that's most pleasing to people is a slight hump in the bass, a flat mid, and recessed treble. For stock systems, I like a "U-curve" with a hump on the bass and treble (because alot of OEM speakers suck at their highs).
