Question

The front right door speaker makes a chirping sound when my bass hits. It is a Rockford Fosgate 6.5 full range coaxial. How do I fix it, and what is causing the problem (on headunit power)?

Answer 1

The chirping sound you're experiencing from the front right door speaker when the bass hits could be caused by a few different factors. Here are some potential causes and solutions:

1. Distorted or clipped signal: When the bass hits, the speaker may be receiving a distorted or clipped signal, which can result in a chirping sound. This could be due to the power output of your head unit exceeding the speaker's capabilities. To fix this, you can try reducing the bass levels or overall volume on your head unit to prevent overloading the speaker.

2. Wiring or connection issue: Check the wiring and connections between your head unit and the front right door speaker. Loose or damaged connections can cause intermittent noises. Ensure that all the connections are secure and that there are no loose wires or frayed cables. If you find any issues, reseat the connections or replace any damaged cables.

3. Speaker damage: The chirping sound could indicate a problem with the speaker itself. It's possible that the speaker cone, voice coil, or another component is damaged. Inspect the speaker visually for any signs of physical damage or deformation. If you notice any issues, such as a torn cone or voice coil rubbing, the speaker may need to be replaced.

4. Inadequate power handling: If your head unit's power output is too high for the speaker's power handling capacity, it can cause distortion and damage to the speaker. Ensure that the power rating of the speaker matches or exceeds the power output of your head unit. If the power mismatch is significant, consider using an external amplifier to power the speakers, as they typically offer more control over power output.

5. Environmental interference: Sometimes, external factors such as electrical interference from other devices or poor grounding can introduce unwanted noise into the audio system. Check for any potential sources of interference near your head unit or wiring, and ensure that your system's grounding is solid.

If you've checked all these potential causes and the problem persists, it may be beneficial to consult a professional car audio technician who can diagnose the issue more accurately and provide specialized assistance.
