If your car speaker is making a high-pitched noise, inspect the alternator and ground connections. Inspect and fix problems with both areas of interest, and you should have clear sounds from your stereo. Or it may be a problem with the antenna connections. Sometimes, the high-pitched noise coming from the car speakers may be due to a faulty antenna. While checking ground connections and the radio, one component that often goes under the radar is the antenna. Therefore, using it as a grounding location means inviting them into your car stereo’s output. Ripple noises from vehicle components like the alternator all reach the negative battery terminal. While it’s a fantastic grounding location, it’s a bad idea if you’re dealing with audio equipment. Many people wrongly assume the negative battery terminal is the best grounding location for car speakers. The best method for grounding your car speakers involves running 12 or 10-gauge wiring from the amp and 12-gauge wiring from other stereo parts to a single location. If there’s still a high-pitched noise coming from your car speakers, it’s time to consider the location of the ground connections. Use a ground loop isolator to suppress the noise coming from the ground points. Likewise, you can check all other ground connections like the battery posts, crossovers, equalizers, and ground posts.Īfter confirming the ground connections, you can ensure your work by putting a protective system in place. You can start by checking if the ground cables connect directly to the chassis of the car.Īfter that, confirm the condition of the charging system of the speakers. You’ll need to check the ground connections to fix a high-pitched noise from your car speakers. If the ground connections are bad, it’s only a matter of time before the stereos begin to misbehave. The ground connections of your car stereo components are as important as the stereo itself, if not more. By doing so, you’ll be preventing the spark plugs from affecting your car speakers in the future.

In some cases, you may need to overhaul the entire wiring system. Perhaps, a wire got dislodged, and you just need to fix it. Start by checking for issues in the wiring connecting the spark plugs to the speakers. If there’s something wrong with the spark plugs, it’ll manifest in the form of high-pitched noises. The wires connecting the spark plugs of a car to its speakers are essential to the sound it makes. Or perhaps there was an issue with your radio’s connections.Īnother common culprit of car stereo noise is the spark plugs in your vehicle. If there’s a clear difference between the sounds, your radio may be the source of the problem. You can do this by switching to a radio that’s working in another vehicle. In some cases, the bad sounds may be due to the radio playing the sound.Īn easy solution is to check whether the radio is in good working condition. Sometimes, the high-pitched noises may not be a function of the speaker. Even if the alternators generate a high-pitched noise, the filters will block it from the car speakers. You can also install one in the head unit’s power cable. Check the alternator whine when you hear strange sounds coming from your speakers, especially the ground connections.Īnother option is installing a noise filter between the car battery and the alternator. In no time, you’ll have alternator whine sounds in the speaker. Perhaps your vehicle mechanic was in a rush and fixed a ground position on bare metal. This alternator defect occurs due to ground connections in the component’s position. As the speed increases, the sound from the alternator whine increases. When you have a high-pitched noise coming from your car speakers, the first suspect is the alternator.
