How to Solve Resonance Noise in Car Audio?
2 Answers
Solutions for car audio resonance noise: 1. Redo the full car sound insulation: Some car audio resonance is caused by poor sound insulation measures, and redoing the full car sound insulation can solve the problem; 2. Replace the audio system: Resonance caused by poor audio quality requires professional repair or replacement of the audio system; 3. Install an equalizer: After installing an equalizer, the sound should be set at around 70%; 4. Adjust the amplifier frequency points: Generally, the front sound field amplifier should be set between 80Hz to 120Hz, the rear sound field amplifier between 200Hz to 350Hz, and the subwoofer amplifier between 80Hz to 120Hz.
I used to frequently experience a buzzing sound from the audio system while driving, feeling like the doors or trunk were vibrating, especially when playing bass-heavy songs. I solved it myself a few times: first, I lowered the bass settings on the audio system to avoid excessive low frequencies; then, I checked if any interior panels were loose, like the door handles—I found some loose screws and tightened them with a screwdriver. I also moved items in the trunk to prevent collisions and resonance. If the noise persisted, I used some soundproofing foam to fill the gaps, which can be bought cheaply online. After these fixes, the car became much quieter, and driving was less distracting. Remember, resonance is usually caused by loose components or improper audio settings—taking a little time to address it can save you repair costs.
