If you have an alternator whine in your speakers, there are a few things you can do to try to get rid of it. First, check all of the connections to make sure they are tight and secure. Next, check the ground wire to see if it is properly connected.
If neither of those solutions works, you may need to replace the alternator.
- Check your car’s audio system to see if the whine is coming from the speakers or from somewhere else in the system
- If it’s coming from the speakers, then proceed to step 2
- If it’s coming from elsewhere, then try troubleshooting that part of the system to see if you can fix the issue
- Identify which speaker is making the whining noise
- This will be easier to do if you have a sound system with multiple speakers
- Once you know which speaker is causing the problem, proceed to step 3
- Inspect the speaker wire connections at both ends (at the amplifier and at the speaker itself)
- Make sure that all connections are tight and secure
- If any connections are loose, then tighten them up and see if that fixes the problem
- Try moving around the wiring in your car’s audio system, especially near the affected speaker(s)
- Sometimes alternator whine can be caused by electromagnetic interference (EMI) from other parts of the wiring harness, so moving things around may help mitigate that issue
- If you have aftermarket accessories installed on your car (like an aftermarket stereo or amplified subwoofer), then try disconnecting those accessories one at a time to see if any of them are causing interference with your audio system

How Do I Stop My Alternator Whine in My Stereo?
If you’re hearing a high-pitched whining noise coming from your car stereo, it’s likely that the alternator is to blame. Alternators are responsible for generating the electricity that powers your car’s electrical system, and as they age, they can start to produce a higher-pitched whine.
There are a few things you can do to try and reduce or eliminate the alternator whine in your stereo.
First, make sure that all of the connections between your alternator and your stereo are tight and secure. If there are any loose connections, tighten them up.
Next, check the ground connection between your alternator and your car’s chassis.
If the ground connection is loose or damaged, it can cause interference that will amplify the Alternator Whine. Tighten or replace the ground connection as needed.
Finally, if none of these solutions work, you may need to replace your alternator altogether.
Depending on the make and model of your car, this may be something you can do yourself (if you’re mechanically inclined), or you may need to take it to a professional mechanic or auto shop.
Why is My Car Stereo Making a Whining Noise?
If your car stereo is making a whining noise, there are a few possible explanations. The most likely cause is that the power supply to your stereo is not clean. This can be caused by a number of things, including bad ground connections, loose wiring, or a problem with the alternator.
If you have checked all of these things and the problem persists, it is likely that the stereo itself is faulty and will need to be replaced.

How to Fix Alternator Whine
If you’re hearing a high-pitched whine coming from your car’s engine, it’s likely that your alternator is the culprit. Alternator whine is a common electrical problem that can be caused by a variety of factors, but fortunately, it’s usually relatively easy to fix.
The first thing you’ll want to do is check all of your car’s ground connections.
A loose or corroded ground connection can cause alternator whine. Be sure to clean any corrosion off of the terminals and tighten any loose connections.
Next, take a look at your alternator’s pulley and belt.
If the pulley is misaligned or the belt is too tight, it can cause the alternator to work harder than it should and produce noise. Adjusting or replacing these parts should fix the problem.
Finally, if none of these solutions work, it’s possible that your alternator itself is faulty and needs to be replaced.
This isn’t a very common problem, but it does happen from time to time. If you suspect that this may be the case, take your car to a mechanic for diagnosis and repair.
Conclusion
If you’ve ever heard a high-pitched whine coming from your car speakers, it’s likely caused by interference from the alternator. Alternator whine is a common problem with many cars, but there are a few things you can do to get rid of it.
First, make sure that all of the connections between your alternator and your stereo are tight and secure.
If they’re loose, it can cause electrical interference that will show up as noise in your speakers.
Next, try grounding your stereo system. This means connecting a wire from the negative terminal on your battery to a metal point on your car’s chassis.
This will help to reduce the amount of electrical interference that’s reaching your speakers.
Finally, if you’re still having problems with alternator whine, you may need to replace your alternator. If it’s old or damaged, it may be causing more electrical interference than a new one would.
Alternator replacement can be expensive, so make sure that you really need it before you spend the money.
