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.
