Have you been observing lousy noises or high-pitched whining that gets louder through your stereo system as you press on the gas pedal? If yes, you must have the engine or alternator of your car interfering with your car audio sounds system.
Now, here’s how to Get Rid of Engine Noise in Car Stereo.
You might be experiencing this change in your stereo frequency as your engine is been raised or as the engine is being worked up. No worries as there’s a solution to the problem and this guide will help you get rid of these engine noises disturbing and interrupting your music enjoyment.
The main objective is to find out the main cause of the problem as the engine of your vehicle may not only be the cause of the disturbance you get while listening to music on your stereo.
You need to know that more than just one factor could be the cause. From using inferior RCA cables down to fitting your speakers near power cables, either of them or both can be the cause of these noises you get.
The cause of noise from your stereo system could be caused by some of these reasons.
You might be experiencing buzz and hiss in-between the sounding of your stereo system as a result of your amplifier connections not been earthed properly.
This can allow easy distribution of vibrations to penetrate through the car stereo sounds as wire connections not properly grounded could be a major cause of picking engine noise and distributing them through the vehicle’s speakers.
It can also be that the stereo ground wire is located near noise sources like the heater, air conditioning e.t c, if you have spotted any of these, space the connections from the ground connections wire to stop the noise.
If you only experience these buzz, hums and other unpleasant sounds when you turn on the radio of your stereo. The cause of your problems leads us to the only culprit which is your AM/FM antenna, you might be getting noises from the antenna lead as your engine works.
If you remove the antenna and the noise persists then you are advised to try an antenna suppressor. The suppressor helps filter plug and the line between the antenna and your receiver, breaking the ground path between them, preventing further noise interference.
Alternator and Engine Noise
You may experience noise through the ground wires linked to the receivers and the pitch of these noises vary with engine speed. If it is engine noise, you should hear a clicking or whining sound.
If that is the case, to solve this problem you will fix an alternator noise filter on the power line between the battery and the alternator to subdue the effect of this problem or you can install it on the receivers’ power lead to reduce signal interference.
Where is Your Amplifier Mounted?
Where your car’s amplifier is mounted can play a role in reducing or causing noise in the car stereo soundings although most car audios like the JVC KD-X370BTS are good in resisting interferences.
It could be placed where the source of disturbances originates from and if so, you should immediately change the location of your amplifier. If your amplifier is not fastened or attached to your car’s chassis it could result in noise pollution.
The amplifier having contact with any metal of the car’s body contributes to the whole mess, so if you notice any of the above to be the problem immediately rectify this problem to stop further disturbances.
Noise in Speaker Wiring
Noise might also come through the speaker wires. To confirm the noises are from the speakers, turn the system off and disconnect all speaker wires from the amplifier. Now start the car.
If the noise persists, then it’s being radiated into the speaker wire. Reposition them, or, as a last resort, shield them by wrapping them with a metal foil.

Installing an interference or noise Filter
Another way to get rid of engine interference in your vehicle speakers is to make use of a filter. They are also known as ground loop isolators followed with a long cable and filter unit attached to a socket.
You can install the filter by inserting the plug in the sockets of your car audio and link the RCA cable to your speaker. Take note that including RCA cable to your filter and adaptor cable will have 1 stereo/ audio plug on a particular end and 2 RCA cables at another end.
You can get an adaptor before starting the installation.
Reconnect and Reset Speaker Wires
If you have disconnected your amplifier cables from the stereo and match on the accelerator of your vehicle and you still hear noises from your speakers. At this point, you will have to reconnect your speaker wires and connection or it could be the speakers are faulty and they need to be changed.
As mentioned earlier, improper grounding connections can cause unwanted and unpleasant sounds as resistance against engine vibrations are at its minimum. The electrical charges caused by the engine get picked up by the wires, which generates unpleasant noises.
This problem also occurs if the negative part of the cable is not properly connected to the body of the vehicle which will need the experience of a technician to handle and rectify.
Use high-quality cable for your amplifier
Electricity is synonymous to running water. You cannot run a hose from the house to the well because there is insufficient water to make ends meet. For this reason, you don’t have to use inexpensive low-power cables to power your amplifier. When you press the control switch, the amplifier becomes power-hungry.
A good cable allows free electricity, so your amplifier gets the juice needed during peak consumption. High-quality cables ensure better flow of signals from the receiver to your amplifier, so you can hear a focused and detailed sound.
A good patch cord also eliminates the interference caused by the electrical system of your car. Don’t you believe that? Ask any guitarist about the need for a good cable.
