The optimal setting parameters for Kugou car sound effects will actually vary depending on personal preferences and the specific conditions of the car audio equipment. However, here are some common settings that can be used as a reference:

Equalizer: Adjust the frequency response curve to achieve the ideal sound balance. Generally speaking, you can try to add some gain in the low frequency (bass), mid frequency (midrange) and high frequency (treble) to improve the bass and treble details.

Soundstage Mode: Some car audio systems provide a variety of sound field mode options, such as surround sound, theater mode, etc. Choose the appropriate sound field mode according to personal preference to obtain a wider sound field experience.

Volume: Adjust the appropriate volume according to your own hearing needs and safe driving principles.

In-car balance (Balance) and volume (Fader) control: Adjust the left and right channel balance and the front and rear channel balance according to the position and preferences of the passengers in the car to achieve good audio distribution.

Noise Cancellation: Enabling the noise suppression function of the car audio system can effectively reduce the interference of noise in the car on the sound quality.

In addition, you can also try other sound effect settings according to your personal preferences, such as Bass Boost, Sound Enhancer, etc. The best settings should be adjusted to your personal listening needs and preferences, and to balance the sound quality and soundstage experience with your specific car audio equipment.
