What should bass and treble be set at in car?

Bass frequencies are generally between 60 to 120 hertz, mids between 400 to 2,500 hertz, and treble between 8,000 to 15,000 hertz.

How do I set my EQ to the best sound?

First, position speakers for best sound. Next, set equalizer controls to neutral or 0 before adjusting to your listening preference. For brighter treble, reduce mid-range and low-end frequencies. For more bass, tone down treble and mid-range frequencies.
