- Auxiliary Interference - Discovering Ground Loop Isolators
This quick video demonstrates the massive difference a ground loop isolator can make.
Finally after years of searching I have found a solution for the obnoxious sounding feedback resulting from charging a smartphone and listening to music through the auxiliary cord at the same time. I have tried fixing this AUX interference problem by trying multiple cables, different aftermarket stereos, 4 vehicles and even an app which is supposed to remove the static sound from your phone.
After trying all of these methods to find the culprit I resigned myself to the fact that I will just have to live with it. Luckily for me I stumbled across a comment at the bottom of a "How To" forum which suggested to try the ground loop isolator. Instantly after plugging the device into my Chevrolet Cobalt the problem was solved; all of my hard/ tedious work had finally paid off. This car audio problem has been by far the most frustrating issue I have come across with my Chevy. That is why I wanted to film this short video to save anyone else who has been fighting with this stereo interference issue.

Perfect explanation and solution! Took me many hours searching the problem you explained in 10 seconds (Humming noise when power charger and 3.5 mm audio jack connected at the same time). Good quick video. Very little excess jabber. Well done!!
You don't have to worry about this problem on IPhone cause you can't do both.
Grayson may be on PC and I may be on Mac, but one thing is for certain... We're both on Android phones lol. - Marcus
Roads Untraveled mac have u no shame. next time build a pc
Get a radio with a USB in port and you're sorted
I was exclusively PC for the first 18 years of my life. When I went to film school I switched to OSX and i'll never go back, unless for some strange reason I start getting into PC gaming. But my friend Kevin has an epic PC with Oculus Rift and a wheel setup... It's unreal.
Roads Untraveled you can just come over when ever you want and drift in vr
This comment is a how and why its happening with a write up for a BETTER and cleaner fix than whats highlighted in this video:
90% of the time, the issue is engine noise coming through the power lines that powers your cigarette lighter (or aux adapter) - which in turn powers your USB adapter - which in turn is sending the engine noise through your charging cable and into your phone - which in turn is sending the noise through your phones aux port and up into your stereo - which then then gets "amp"lified by the stereo itself. Essentially, this is known as a "feedback loop".
The reason for this is the power lines that powers your cigarette lighter are typically not insulated. Properly insulated wires would prevent engine noise from ever entering the lines to begin with but for a variety of reasons not many cars insulate those particular wires.
The best way to eliminate all the "which in turn"s is to eliminate the noise at the power source. This means wiring in a 12v power engine noise filter device between the power wires and the cigarette light. This typically involves getting behind your dash, or car stereo, and hoping there is enough room to place one of these devices inline. It is a very easy and cheap ($10) fix - and if you do it right it also eliminates the need for external wires (like the video showcases) cluttering up your center console.
The solution in this video is NOT the best method. Yes, it will work. A decent external aux audio filter will typically do the trick. However you also risk the filter actually filtering your music too. ANY time you add audio wires and adapters between the audio source and the speakers you degrade the audio signal. So yes, the above video works, but you are now adding unsightly and cluttering wires to your dash/console of your car all the while degrading the audio signal being sent to the stereo. An example of this degradation is turn your stereo to FM at 50% volume, then switch to audio through your aux port to the stereo - you will hear a NOTICEABLE decrease in volume. THAT is signal degradation. To get back to 50% volume while using AUX you probably need to crank the stereo volume up to 60 or 65% (sometimes higher). And even after getting back to 50% volume, you don't have be an audiophile to hear your music sounds a bit muted or the quality has gone down - again, that too is a result of signal degradation.
So again, the best way to filter audio noise coming through power lines is at (or before) the power source. This "part" is an example of the type of filter you need. I am not advocating this particular filter - there are much better ones one the market - its just a cheap example that would most likely do what you need: www.amazon.com/Baoblaze-Rating-Filter-Engine-Installation .
I hope this write up helps future folks seeking to eliminate engine noise.
Item no longer exists
@@JoseMarquez-mh8ud I just bought and installed PAC CSS12 Passive Noise Filter, 12 Amp, Choke and Capacitor Design from Amazon and it worked for me. I installed it before my cigarette plug so that everything plugged into it, including my BT audio adapter, would be filtered. Engine noise/whine/hiss has disappeared!
Not only car related but I use one of these between my (expensive) Gigabyte motherboard (£5 on amazon, clean looking black box, size of matchbox) and ear buds. Removed 100% of noise at desktop and in game.
The ground loop isolater can be bought at most electronics stores like Radio shack, jaycar electronics in Australia. I used to run multiple earthing points everywhere. Even to the Alternator. Thats where a lot of whining noise in Audio comes from. Also car engine like carby versions. Cheers from Australia subbed and liked 👍
This used to be an issue back in the day with stock wiring when adding amps or other items- ground isolation is key, even spark plug wires were specifically made for 'audio' setups back then.
Good info.
And yeah, I'm talking back in the day with cassette adapters and such, cd's receivers created a whole other array of issues.
Glad you guys got it figured out!
Video started like a bad p*rn intro
😂😂😂
True tho
LMAO 😂
Brazzers would be disappointed
Thanks for this. I had a look and couldn't see where I'd plug the isolator into my car so I looked online and found a car bluetooth device which has it built in. It's an MPOW B2.0 Bluetooth Receiver 2.0 Car Packaging and I just bought two of them on ebay, one for me and one for my son, for $34 Australian dollars each. I'm looking forward to getting rid of the bloody annoying static.
I've been listening to music with static for a long time. Didn't know you could fix this issue. I thought it was the audio source and never fixed it
I had the same issue with my JBL sound system at home...
fixed it with the isolator..
thank you!!
great content!
We hope you enjoy this different type of video exploring an auxiliary issue which I have been fighting with for years. If you have the same issue let us know in the comments below!!
your barely found this out today.......rly
Roads Untraveled I have a problem with my truck but it's only when I plug the aux cord it makes a sound like eeeeee and it just keeps going eeeeeeeeeee what can i do to fix it?
Thanks for please learn what "feedback" is.
@White Amber use a ferrite choke over the power wire to the lee's lights
Just put an emi ferrite core filter on your charger cord. Wrap once. Pretty sure that's all that is inside that fancy box.
The noise comes from the Transformer inside the charger, sending an oscillating frequency back through your system so the filter just simply filters it out.
Thank you so much, I drive for a living and have been having this problem for years.
Happy to hear you found this useful. I have been getting very frustrated over the years trying to find a solution.
I've been using the PAC isolator with MacBook Airs for years now...I have my laptop hooked up via AUX to a 2.1 speaker set up and it's the same thing...without the isolator I get the exact same issue that you do with iPhones....
This is amazing!!!!! I thought it was just me.
We'll see if works in my scenario. I have a Mobile HAM radio installed in my Chevy Tahoe. Power is supplied directly from the battery, and then I have 3.5mm aux cable running from the HAM receiver to the aux input on the car's radio receiver. I get a humming noise that is a result of interference from the alternator. Today, I took delivery of ferret cores hoping that would eliminate the issue. I put a ferret core on the aux cable just before it plugs into the car radio aux port; and I put one on the positive power cable from the battery. No dice. So, I just ordered a BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable. Hopefully it arrives tomorrow and solves this annoying issue.
Thanks for saving my endless headache in the car. You rock!
Crazy, I've had this problem on all my phones except the Galaxy S7. Even when my friend and I had the S5 it only happened to mine. Big ups for this video.
Lifesaver! Had this issue and didn't know what to do
Haha I am glad to hear that this helped someone. I thought I was the only one due to the lack of information that is out there :-P
Noise from the charger is jumping onto the Aux output on your phone. Usually it's from a bad earth/ground on the socket or a cheap bad quality charger and sometimes unshielded cheap cables.
Bro I just bought a Chevy Cobalt 09 and have this issue and it looks like that's what you're driving.
I'm ordering this and I have to thank you a million for this. It's been driving me fucking insane!
Update:
This ground loop device works perfectly!
After scrounging around on Amazon the KRIPT ground loop isolator seems to be the best device. It's a little more but what's that matter when you get good quality?
Reviews of people who bought this device and others went with the KRIPT.

what about bluetooth? when my phone is connected and music is playing I can hear hissing static sound. it's not super loud, but it is there and it's annoying
There Bluetooth models as well
I am glad I found a quick result for this issue
Thanks so mich for this. I have had this problem for years. You solved my issue as well.
Thanks dudes. Was having this problem for ages. Ordering one.
I wish I saw this video many months ago, I had this issue with my Bluetooth-to-Aux dongle. The dongle needed to be powered by USB from the car's 12V line and this introduced that hissing noise. I had to resort to powering up the dongle from a power bank instead of the car's power as the power bank didn't have the same noise issue (buttery smooth DC power). In the end, I bought a high end Bluetooth-to-Aux dongle which seems to filter out the noise.
Thank you so much! I've always had this problem in my E34 and now it's gone! I thought it was just my phone cuz ive tried many aux cords and in my f30 this doesn't happen cuz well Bluetooth. This even happened to me on a iPhone and my nicer Android phone fyi for those people saying just by a iPhone lmao na I'm good screw that
How would you make this work with the oem radio using Bluetooth??
The fact you have the same car I do but black is how ik this will work😂😂
has anyone else never had this problem?
Nope. Had 5 or 6 head units with just as many phones.
I had the issue when i first bought my s7 edge and my note 9 but there was a certain setting that I changed and it went away...
@@Pfeiffer-fp2se What did you change setting wise on your Note9? I have the Note10 and the Aux volume SUCKS!!!!
I've heard of them, but fortunately I've never needed one for whatever reason. I would definitely like to see the detector video though!
I found this randomly! Thanx 😊 this was a huge help.
My old truck that I daily drive doesn’t have a working radio and I have been using Bose computer speakers to play music. For a while I’ve always had them plugged into a power inverter which had a built in USB port to charge my phone and I never had any problems except it would stop working then the engine was at idle and I wondered if my alternator was going bad but it was charging just fine. I realized that the input voltage on the speakers was 12v and a found a car plug with a barrel jack on the end that fits into the speaker. Therefore I could do away with the noisy power inverter. My truck only has one car outlet so I bought a splitter so I can have sound and charge my phone at the same time, except there was a problem. Whenever I plugged the charger cable and audio jack into my phone at the same time, there was a loud deep rumble that came from the speakers at all times, even at the lowest volume. It would never do it if I was only using the audio cable or charging my phone separately, only when used together. I thought the splitter was defective so I exchanged it with another one and it did the same thing. Then I stumbled by this video and as soon as he said “ground loop isolator”, I remembered that I got a box of random car audio parts that Best Buy’s was throwing away and I thought there was one in there. As a matter of fact, there were two of them, high quality ones in metal cases. The only issue is that the inputs and outputs are RCA and not 3.5mm jack. That was no problem because the inputs on the Bose speaker was RCA so I just connected a small patch cable that I soldered up from the random AV wires in that box from Best Buy’s. And holy cow it works! I can now listen to music and charge my phone with no audio feedback or interference.
1:36 this guy is really dedicated to solving the problem because he bought whole other cars to fix the sound buzzing from his phone
(I'm kidding obviously he didn't buy other cars)
You could have started the video at 2.00 and finished at 4.00, or just told us to buy an islolator. But thanks anyway. Good job.
What about the fix for the usb charger and radio???
We all need to charge something in our vehicle. And many times, while using the usb charger when listening to our local radio station, the static happens.
This has annoyed me for ages. Great fix
yes this actually has been annoying me, especially since a road trip to uni is an hour+ long and the stupid audio is just hissing
Keep up the awesome videos! I love seeing local content :>
Has ground loop isolator .
Keeps under passenger seat instead of plugged into aux.
Anyone have a problem when the aux is plugged in but when try to charge my phone it cuts off aux and goes to fm am radio , I unplug the charger then aux comes back in let me know fizellas
But then again this man put me on id buy from him if I could wait
IDK what I did wrong...I plugged it in and not only the loud noise was gone but so was the music. Any Help???
This is generally interference coming from the alternator. However in this case it seems the car is off. I've really never had that issue in any car??
I never had this problem .. and I did it with about 4 cars
did you connect with bluetooth?
My 2011 Toyota Venza always had great sound when I connected via Bluetooth BUT NOW my sound is at MAX and I can still talk over the music. Someone said "get a sound shocker" I need my music LOUD, help
i have two other possible solutions for you.. drive Ford or use bluetooth... for some reason the ford aux cables usually don't cause interference like this
I have had the same issue with a C63 AMG, 2010 Silverado, Nissan SUV, 2014 Subaru Legacy, etc.
I bought a Ford Fiesta the other day and now I'm on this video searching for a solution to my god awful Aux static.. Your comment is false
my s2000 has a pioneer deck that has a USB port. I listen to music through an Apple usb which not only charges my phone (while listening to music and just driving around) but also has stellar quality compared to AUX.
Mine does it when my phone isnt plugged in to the aux cord. How do i get rid of that
Are you saying your car stereo always has engine whine OR that you get engine whine when simply charging your phone (not even aux'd to the stereo) OR are saying your are getting engine noise with aux plugged in but NOT charging the phone...some other combo?
If you are getting engine noise simply charging your phone (and no aux cable to stereo) then your feedback loop is def happening through your power lines. For a fix, read my most recent post above.
If you are getting engine noise through your aux while the phone is NOT being charged then your issue a bad or weak aux cable (not properly insulated) that is picking up engine noise on the way back to the stereo. If you have a good cable or the cable is all external (meaning its sitting on your console) and simply plugs into a front facing AUX port directly on the stereo then my guess is you have a bad or cheaply made stereo - and your stereo aux port is the culprit.
FYI- It's best to avoid charging your phone in the car or through any other "12v outlet" all together. Also, using your phone while it's charging is not conducive to optimum battery life. Ideally, all apps should be closed and battery charge should be maintained in the 40-80% range using the original charger attached to a clean power source.
just enjoy ur phone ffs😂
Another easy way to do this is use a power bank, Use the cars power to give charge to the power bank and then pass-through to the phone. Because "technically" you arent using the cars charge directly it will give you the same result.
Let me see if you can help me with my problem.. Iam using Aux in my Mercedes for watching videos as it's 4 pole 3.5mm connector carries both Audio and video.
Iam facing the ground loop problem with Audio.. However The video and Audio is carried via the same 3.5 mm connector ( 3 lines on 3.5mm head, any solution or noise separator with 4 Poles 3.5mm connector)
I tried 3 different aux cables and 1 of the cables almost completely removed the noise.
Its funny i watched this video in my car through aux xD
Explain to me how to eliminate the noise ppl hear when I'm talking to them Bluetooth via my car stereo...it's an aftermarket Sony...just installed and when I'm driving, they say there's alot of noise like wind or something on their end....but I can hear them loud and clear.... Need help on this one
Tnx one problem down.
Mby you know the answer to why when using a TRS cable with my phone on my car it makes mono sound (L) and when using TRRS it goes to stereo and everything's fine.
So my issue is if I have my (iPod classic yes I have one) via aux and my phone plugged into a car lighter port. It switches from aux audio to video and keeps trying to play a video. It's why.
Does that happen while your phone is NOT charging?
now how do i get an aux plug in on a oem stereo i like enough to not change. fm transmitters seemed to suck
I have a Moto G7 android. I tried plugging in an aux. cord and get alot of static, is my port bad or do I need something like this? Thanks
Omg finally!! I thought it was only my radio! I'm going to but this thing now!
Hey cool. My card was accepted. I just wish the numbera made more sense
I have an s8 had this problem also.. went into the music settings.. switched the eq and it instantly went away.
Hi guys. This is an easy fix, but not a propper fix. It would be much better to connect the lighter socket ground to radio ground. This fix is way better and surprisingly much cheaper (one wire and couple connectors). After this mod you won't need this toy anymore.
Thanks for the tip. I am looking at selling my car so I don't want to open anything up at the moment but due to us driving different cars every week we would not have the opportunity to do that to every car.
Thanks for the Info!!
No problem :)
There will be most likely two small transformers (one for each signal) to decouple the grounds between your phone and radio.
How? there is any video of this? I have the same problem with 2 cars...
please can you tell us how to do this?
Can you show the difference in sound when phone isnt charging?
Yes I have this problem! Do I have to buy the aukey chord with it?
I wish I knew this solution a year ago instead of spending money for a expensive stupid factory Amp adapter on a mk4 Jetta which prevents this issue when he could have cut the wires to the amp and I could use this noise thingy.
thank you my car does it without charging a phone its faint but it is noticable and slightly worse when charging a phone now i need to get one of these for use all the time xD
I am having that issue with my car right now, I bought commander touch Sirius xm and there's a lot of interference :( I been desperate, and hopefully that'll work. I'll let you know
Have same issue but only on Bluetooth mode. Will this work somehow?
what if my car doesnt have a aux jack my car is a 96' mercury sable
thanks guys that's really helpful I been having the same problem for ages lol.
Glad to help!!
How about if this happens in a Bluetooth radio ? The hissing sound is there can anyone guide me to a tutorial?
it probably depends on the phone with this issue my new Google Pixel doesnt have this issue
I've tried these and they all significantly degrade the audio quality. I don't recommend them if audio quality is important to you.
Did you ever fix your driver side headlight?
Is this works on FM&AM on my car radio or just for AUX?
Hats off to you man 💯
also people suffer from low volume from the phone which could be a impedance mismatch between the phone and car aux
Neato
yup, my is250 do that shit, thanks guys.
maybe it relates to where the charge port and aux port location is
cause all my past phones had them on opposite ends
and I had no problem
but my friends' Samsung and IPhones did it all the time
not rly, have this happen on old nokia lumia which is only used as music device and it has charge port on one end and aux on the other.
I love cracklin' sounds! 3:11 Cracks!!! 3:15 Different
PAC isn't a chinese generic. They work alongside Stinger.
I dont think this happens with aftermarket head units.
dacasman depends on the head unit, doesn't happen on my JVC one but happens on my old sony one
thank you, that was exactly what i needed
Did you find something for doing the same thing listening to a Bluetooth device in the cigarette lighter.
I'm having this issue as well.
This RUclips video doesnt give me feedback but my spotify does... help?
Poor isolation of the different electrical groundings. I assume this doesn't happen on other cars with the same combo.
I have tried it with 4 cars from different manufacturers and all 4 have the same issue
Roads Untraveled What about with different chargers?
I have tried multiple chargers, 3 different phones, different aux cables and even an app that was supposed to fix the issue.
Roads Untraveled That's just bizarre, DC voltage is leaking in somewhere. I've never had this issue, presumably as the combinations I've used have good ground isolation or inbuilt circuitry like that in this device.
Either way you don't have the issue now, which is great!
Just for the record, this doesn't happen with my MR2 :) - Marcus
Thank you! Finally I have a solution:)
WATCHING THIS VIDEO AND HEARING HE SAID AUX BRUHHH LIKE WTF IS CALLED BLUETOOTH JUST GET A PIONEER 4660 NEX
did you buy a cheap Chinese $10 charger? I have a Motorola Droid 2 Turbo and I've never had this issue, before that I had a LG G2 didn't have that issue either. I always buy the 1A chargers. Never have this issue, sometimes I get like a cellphone reception radio thing that happens but then immediately it goes away, kinda like the unheralded radio signal most phones exhibit on speakers when close by.
All of my chargers have been either brand name Samsung or high end aftermarket. I had this problem with my last phone as well as my new phone which was used in the video.
On the same car?.. Maybe issues with grounding in your audio system?
I have had the same issue with a C63 AMG, 2010 Silverado, Nissan SUV, 2014 Subaru Legacy, etc.
I have used different charging cables, Aux cables, chargers (including trying a power converter in which I plug a wall charger into)
As you can see this has been extremely frustrating :-P
I drove a Hyundai Sonata GLS 2010, and now a Nissan Altima S 2015 model, same, no issues what so ever. After market stereos? Same installer? Seems like a pattern happening. Generally when you don't hear about this kind of stuff happening many places, it means something is common in the environment that you're in is the same / happening multiple times. I know you think this is common but I've never seen this happen and I worked at a mobile software development company and they had plenty of people to complain about this issue.
Pineapple doesn't go on pizza.
Also please make moar R32 videos. K thanks. Bye.
We drove a pink widebody and bagged R32 GTR last weekend :) stay tuned
Pineapple belongs on Pizza.
idk, i have no problem. sony xperia with 24bit dac and charging playing music just clean fine.
Never mind the AUX issue...Fix the issue with those shoes. What in the fuck are those?
Headlight out in beginning hahahahaha good video had to say it
Issue goes away when using an iPod or Bluetooth audio receiver. Strange...
I think its because on the bluetooth device the ‘dirty’ ground signal is not connected to the audio input of the amplifier. While in a splitter they just put the two grounds together, and the one coming from the 12V plug has static.. I need to buy a filter it seems, I have this problem in my ford :(
..and if you want to pop out your speakers to hell, just plug in and out like that! ;)
use decent aux cords? there are shielded cords as well
I have tried a variety of cables from cheap to expensive, no luck
Shielded cords is the key phrase. Look into why you get ground noise.
yep that's typically the solution if you're getting static from your line in. it's already really weird he experience this with multiple cars, so I'm guessing he's using some cheapo wires from amazon because I highly doubt multiple cars has the same problem causing static, either it's the wire or the phone itself.
that doesn't work.
Didn’t work for me :/
dude you are my hero
