Haval H6's audio system static noise causes and solutions are as follows: Causes of static noise in Haval H6's audio system: Static noise in Great Wall Haval H6's audio system can mostly be categorized into electrical current noise and bass noise. Other possible issues include: circuit board discharge (clean and dry); tail connector leakage (clean and dry); damaged or poor-quality speaker diaphragm; short circuit or leakage in flexible flat cables; loose soldering or leakage in audio peripheral components. Solutions for static noise in Haval H6's audio system: Replace mid-low frequency speakers, add tweeters, and install crossovers; apply door vibration damping and sound insulation to prevent resonance; upgrade to a higher-power and better-quality CD head unit or all-in-one head unit.
My H6 also had speaker noise issues before, and I had an experienced mechanic check it. Buzzing or crackling sounds are usually caused by loose speaker wire connections. Lift the trunk trim panel and check if the connectors are tight. If the audio system was modified, it might be due to a reversed crossover or poor grounding of the amplifier power cable. Sometimes, it's caused by Bluetooth lag—just restart your phone and reconnect. If it's a humming noise, it's likely alternator interference, especially common in older cars—check the battery ground cable. If the problem persists, visit a 4S shop for a computer diagnostic on the head unit module. Remember to rule out simple issues first, like trying a different charging cable to check for phone interference.
Last time my friend's H6 had audio issues, I helped look into it. There are several types of noise: a crackling sound might be due to a dirty CD player laser head—just run a cleaning disc a few times; a rattling noise is likely from a torn speaker edge—lightly press the paper cone to check for friction; a buzzing electrical noise points to the amplifier module—feel if the casing is hot. For modified cars, pay special attention to cable shielding, as cheap RCA cables are most prone to interference. During regular maintenance, avoid spraying perfume near the speakers, as solvents can corrode the diaphragm. A simple self-check method is to switch to an AM radio station—if the noise follows, it's a signal issue; if it stays the same, the hardware is faulty.
