How to adjust the equalizer for the GL8 audio system?

Increase the treble to a positive six level and move the overall sound field to the rear seats at negative three or four. Adjust the bass to about four-fifths of the midrange, and adjust the midrange according to personal preference, recommended to be about two-thirds of the treble.

My GL8 is primarily used for client transportation, and I've developed a sound tuning method tailored for business scenarios. First, locate the six-band equalizer interface in the 'Sound Settings' on the central control screen. Reduce 100Hz by 2 notches to avoid muffled bass, increase 400Hz by 1 notch for clearer vocals, leave 1kHz unchanged, boost 6kHz by 2 notches to enhance instrument texture, and avoid adjusting 16kHz to prevent harshness. The key is to shift the soundstage positioning two steps forward, ensuring music doesn't overpower conversations in the rear seats. For testing, use Tsai Chin's 'Ferry' - you should hear deep yet non-overwhelming drum beats, with vocal imaging correctly positioned above the dashboard. Never activate 'Rock Mode' as clients may find it tacky.

Families with kids need to balance nursery rhymes and navigation sounds! Here's how I adjust it when taking my child out: Enter 'Audio Settings' in the center console to adjust the equalizer. Boost the 200Hz band by 3 notches for adorable Minion voices in cartoons; lower the 4kHz band by 1 notch to prevent kids from saying 'ears itch.' Most importantly, enable 'Speed Volume Compensation' so the volume automatically increases on highways. During testing, play both 'Peppa Pig' and navigation voice simultaneously—only when both fairy tale dialogues and 'turn right ahead' are clearly audible is it successful. Remember to save these settings as 'Parent-Child Mode' for easy switching next time.

Enthusiasts can try these settings: enter engineering mode and turn off all sound effects. Set bass at 63Hz +2, midrange at 500Hz -1, and treble at 8kHz +3. Test with "Hotel California"—the intro drum should be snappy without dragging, and the shaker should have noticeable granular texture. Focus on soundstage positioning—pull the center point to about 15% right of the windshield's center for the most balanced driver's seat experience. If equipped with BOSE audio, remember to disable Centerpoint virtual surround in the central sound settings, as the factory tuner claims this yields a more natural soundstage.

Long-distance driving advice: First, restore the default settings! Set bass to 100Hz +1 notch to prevent fatigue, midrange to 1kHz -1 to avoid harshness in conference calls, and leave treble at 10kHz unchanged. Activate the 'Driver Priority' mode to focus the music on the driver's seat. Key step: Play frequently listened radio stations and make fine adjustments while driving. I found that reducing the middle frequency band of the equalizer by 2 notches significantly reduces wind noise interference with music during highway driving. The GL8's trunk is prone to low-frequency resonance. If you notice a buzzing sound from the rear door, reducing the low frequency by 3 notches is most effective.

Attention to car enthusiasts who just modified their audio system: For those who installed a DSP, adjustments should be made via the knob, as the equalizer in the original car screen will become ineffective. A tip from the engineer when I installed my Alpine system: Start the engine before tuning to ensure stable voltage. Use three test tracks: "Dabancheng Girl" for vocal imaging, "Drum Poem" for low-frequency transients, and "Pipa vs. Saxophone" for instrument separation. Focus on checking if the speakers above the second row are out of sync—if so, fine-tune between 400Hz-800Hz. After modification, it's recommended to set the mid-high tones 1-2 notches lower than the factory parameters, as aftermarket speakers have higher sensitivity.
