Adjusting Audio Settings
Start by resetting audio settings to default after the update. Then, adjust bass, treble, and midrange levels to suit your taste. Balance the left and right speakers to avoid uneven sound. Set the fade control to spread sound evenly between front and rear speakers. Use the equalizer presets if available, or create your own settings. Take your time and listen carefully to each change.
Testing Sound Quality
Play different music genres to check sound clarity and balance. Listen for any distortion or unwanted noise. Check if vocals and instruments sound natural. Adjust settings again if needed for better sound. Test the volume levels at low, medium, and high to ensure no cracking or buzzing. Drive around with music on to experience real conditions.
