Understanding Car Amplifier Noise
Car amplifier noise, commonly known as ‘humming noise’, is a common annoyance that can ruin the whole audio experience. Whether you are a music enthusiast or love to enjoy long drives, a humming noise can distract you and make your vehicle’s audio system unpleasant.
However, understanding the root of the noise is the first step to getting rid of it.
Types Of Car Amplifier Noise
There are different types of noise that can be produced by a car amplifier. The most common one is humming, but it’s not limited to it. Here is a list of the types of car amplifier noise:
- Humming noise: A low-frequency noise that occurs when the signal ground is faulty.
- Whining noise: A high-frequency shrill noise that occurs when electrical systems interfere.
- Popping noise: A sudden popping sound occurs during start-up or shut down of the amplifier.
Causes Of Car Amplifier Noise
There are several reasons why a car amplifier might produce humming noise. The following are some of the most common causes:
- Ground loop: This is a situation where there is more than one ground path in the signal chain, resulting in a 60hz hum.
- Poorly shielded cables: Cables that have poor shielding will pick up interference from other electrical systems, resulting in a whining noise.
- Faulty alternator: If the alternator is faulty, it can create a whining noise when the engine is running.
- Loose or corroded grounds: Loose or corroded grounds can create a humming noise.
Symptoms Of Car Amplifier Noise
The symptoms of car amplifier noise vary depending on the type of noise and its cause. Generally, these are some of the common symptoms:
- A low-frequency humming noise that increases with the volume.
- A high-pitched whining noise that changes pitch with engine rpms.
- A sudden popping sound during start-up or shut down of the amplifier.
By understanding the causes of car amplifier noise, you can take the steps necessary to get rid of it. In the next post, we will take a deep dive into how to remove humming noise from your car amplifier.
Step-By-Step Guide To Removing Car Amplifier Noise
Removing Humming Noise From Car Amplifier: A Step-By-Step Guide
Are you fed up with the annoying humming noise coming from your car’s amplifier? The good news is that removing humming noise from your car’s amplifier is not rocket science. With a few simple steps, you can eliminate the noise and enjoy an uninterrupted listening experience while driving.
So, without any further ado, let’s dive into the step-by-step guide to removing car amplifier noise.
Checking The Grounding
Grounding is one of the primary causes of humming noise in car amplifiers. Follow the steps below to check the grounding:
- Turn off the engine and remove the key from the ignition to avoid any electrical shock.
- Locate the grounding wire and check it for any rust or wear and tear.
- If the grounding wire is damaged, replace it with a new wire.
- Ensure that the grounding wire is firmly attached to the car’s metal chassis for a secure connection.
- Check the grounding wire’s attachment to the amplifier’s metal housing to ensure a tight connection.
Checking The Power Source
A faulty power source can also contribute to humming noise in car amplifiers. Follow the steps below to check the power source:
- Check the battery for corrosion, wear and tear, and loose connections.
- Ensure that the battery terminals are tightly attached to the battery posts and not corroded.
- Check the amplifier’s power cable for kinks or breaks.
- Ensure that the power cable connector is firmly seated in the power port.
- Check the fuse on the amplifier’s power cable and replace it if it is blown.
Checking And Securing Cables
Humming noise can also come from damaged or loose cables. Follow the steps below to check and secure cables:
- Inspect all cables connected to the amplifier for any cuts, frays, or damages and replace them, if necessary.
- Reconnect all the cables, ensuring that they are tightly secured to their respective input/output ports.
- Check the rca cables; if they are loosely attached, adjust them carefully, ensuring that they are firmly connected.
Shielding Cables
Electromagnetic interference is a significant cause of humming noise in car amplifiers. Shielding the cables can help neutralize the noise. Here’s how to shield your cables:
- Wrap aluminum foil around the cables, ensuring that all portions of the cables are covered.
- Wrap the aluminum foil with insulating tape to prevent the cables from short circuiting.
Installing A Noise Filter
Finally, if all else fails, installing a noise filter can be a game-changer. A noise filter is an electrical component that helps eliminate unwanted noise by separating the audio signal from the electrical interference. Follow these steps to install a noise filter:
- Purchase a noise filter from a reliable automotive accessory store.
- Locate the input and output cables of the amplifier and connect them to the noise filter accordingly.
- Secure the noise filter firmly to the metal chassis using zip ties or screws.
Congratulations! You have successfully removed the humming noise from your car amplifier by following these simple steps. Hit the road and enjoy your music without any interruptions.
