Imagine you’re going to your long-awaited holiday trip on your wheels, and the moment you’ve pressed the gas pedal, the stereo started sounding like it’s in pain. If that’s what is actually happening to you right now, then relax, you’re not the only one with this hassle.
Actually, this problem has successfully established itself among the most common problems in car stereos. But as you’ve clicked here, we’re guessing you’re more into knowing how to get rid of engine noise in car stereo. Well, you won’t have to go back empty-handed for sure.
So, what are we going to do about that? As the problem can get generated due to lots of reasons, we’re going to tell you each one of them and of course, will give you the solution as well.
Reasons for Engine Noises In Car Stereo
There can be a ton of reasons why your car stereo making whining noise so badly. But like the disease, you need to know the reasons here before you jump to a solution. So, let’s put some light on that first.
Reason 1: Improper Grounding
The easiest way to understand if improper grounding is causing the noise or not is by looking for a buzz and hiss from your stereo or not. If it’s the improper earthing of your amplifier connections, then there’s a high chance of you experiencing that noise.
What it does is make the distribution of vibrations easier, and that makes them penetrate through your car stereo sounds. So, if the wire connections are not properly grounded, it works for picking engine noise, which ultimately gets distributed through the speaker.
Reason 2: Antenna Noise
Do you know that your AM/FM antenna can cause irritating noise through your speaker as well? If you’re really planning to learn how to stop engine noise through speakers, then count this possibility on your list too.
It’s easy to identify if you hear any buzzing sound, hums, or other unpleasant sounds right after turning on the radio. And how to stop engine noise in radio? Well, we’re about to get you that solution soon.
Reason 3: Inferior RCA Cables
The prime function of the RCA cables is carrying the audio signals to different parts of the car stereo. But if you’ve got a faulty one in there, there’s a high chance that it might pick engine noise up. Plus, as you’ll accelerate, you’ll hear a whining noise that will come from the speakers.
Reason 4: Faulty Speaker Wires
If you’re making a list of probable faulty wires that can cause engine noise in your speakers, then you’ll have to put speaker wires on that too. Maybe you’ve heard that these cables are shielded. But the truth is, they’re not always shielded; not the one with poor quality at least.

Engine Noise Through Car Stereo: The 5 Steps Solution
Are you done asking the question to yourself – why does my car stereo make a engine noise? Well, we guess you are, as you now know what was causing that. Now the question is how to fix that up. Don’t worry; following some steps will be enough for that.
Step One: Finding the Source Out
You’ve already seen that there can be a lot of reasons for causing your speaker to bring out engine noise. So, clearly, from now on, you won’t have to count the engine as the only probable source of interference.
In order to find out the main reason for the noise, turn your car stereo on and push the volume to maximum. Make sure you’re doing it when the engine is running. Yes, it can be your engine, too, that’s working as the main culprit here.
But to be sure about that, turn the engine off after doing what we’ve said above. If you hear no noise after turning the engine off, then it’ll be proved that it was nothing but your engine causing the problem.
Step Two: Check the Cables Out
If your engine is not the problem, then go for the next step. Yes, we’re talking about the RCA cables. Pull each one of them out and replace them with the good quality one, but that’s temporary as you need to understand if that’s what’s bringing up the noise or not.
By the way, don’t change more than one at a time. If you see the noise is gone right after the cable replacement, then clearly, the RCA cables were the problem.
Step Three: Pulling Out the Stereo
If the noise is not gone yet, then pull the stereo out of the dashboard and play it. When you see the engine noise is going down or getting vanished, then it’s nothing but the poor shielding that was triggering the electrical interference.
You can fix the problem if you can get to use the magnetic shielding foil, another name of which is Mu-Metal. Take a tin cutter to cut off the Mu-metal strips so that you can wrap the stereo with it and put it back to its receptacle.
Step Four: Shutting the Sound System Off and Disconnecting the Speakers
Well, there’s a chance that you might not be able to fix the noise issue up even after applying the solutions we’ve told you above. In that case, shut the sound system off.
Then, get the speaker wires disconnected. Apply Mu-metal shielding around the wires as the speaker wires being extremely close to the circuitry’s electrical cables can cause the noise. Also, change speaker wire positions as it can get you rid of that irritating sound.
Step Five: Checking the Car Battery and Alternator
Well, this part is about how to get rid of alternator whine. After all, faulty alternators can bring in unwanted electrical impulses, too, and your car speakers can pick that up. Yet, to be sure, check if the whining noise is coming when you’re accelerating.
As a solution, you can get the engine tuned up. Plus, you might need to get a few of the spark plug wires replaced that come with a shielded carbon-core.
Your battery can also generate those electrical impulses. But how to stop whining noise in car speakers when your battery is doing it? In that case, it’s better to send it for maintenance or get it replaced.
Final Words
As a common problem, it’s nothing impossible that your ride can start making those awful noises too. But none of them are going to be a big deal once you crack how to get rid of engine noise in car stereo. All we’ve tried is to make it easier for you. Now, you say if you’ve got something more convenient than this.
