The equalizer on the car audio is an electrical signal device that can be adjusted to different frequencies. Different frequencies produce different sound effects. The equalizer has three sound settings, namely short bass, midrange and treble. As long as it is within the appropriate frequency range, the car audio effect can be the best.

The bass frequency should be adjusted within the range of 60HZ to 250HZ, so that the sound effect will be more relaxed and will not appear too high or too low. Secondly, the frequency of the midrange is adjusted within the range of 1KHZ to 4KHZ. The sound effect adjusted within this range will be very clear and the experience will be good. Finally, the best frequency for treble is 6KHZ to 15KHZ, so that the sound is slim and not distorted.

As long as the car owner adjusts the equalizer within the above range, the sound effect will be the best. The specific frequency can be freely selected within the range according to your own preferences.
