- ***Update - didn’t work.
Important! - when you wrap the wire around the rca jacks, you must loosen a screw on your deck and then run wire under screw, then tighten it up. I didn’t make that clear. Should fix.
Update Update. I’m so glad this is working for a lot of you. For me, it turns out that the wiring harness was busted. I bought a Pioneer DEH-X8800BHS. It SMOKES that Kenwood, so all things happen for a reason. (Just pissed I drove it for years with a shit sound).
Hello!
Was the quality also losing this issue?
When you say the harness was busted do you mean the one that came with the radio or the aftermarket harness that connects to the car?
Thanks bro really. That shyt was driving me bananas. I blown two 18s due to it humming and popping. 555.60 gone. Really appreciate the video bro. My bass knob for my epic center is good now, it don't thump no more when turning my car on or rumble while car running. I'm very happy. Thank you again.
you didnt turn the engine on and rev to test
Didn’t need to. It sounded like shit the whole time. I pinned a comment. It was the wiring harness.
Dude I have been chasing this issue for months. This fixed it 100 percent. Thank you Soo much!!!
I have a kenwood excelon hooked up with rca's to two full range infinity amps powering a set of jbl door speakers.
For your test, I believe you forgot to start the car. Because mine only threw a whining sound when the engine was running, but not with engine off and power on. I'll still try to connect all of the grounds of the RCA cables together to see if it fixes mine.
I had my doubts. Mine was so loud when you turned on the heater/AC fan that it was unbearable. I just did this and it is complete silence. Thank you! BTW, installed dozens of systems and never had this issue. Alternator could be failing or has a bad connection. Still, awesome that it worked.
I did this on my RCA , but then no sound comes out. Any ideas ?
@@pollo8993 But you have sound before? If so, it sounds like you may have used stranded wire and some could be touching the inside of the barrel? Is that possible?
Yes i have sound before grounding the RCA.
@@pollo8993 Not sure on that one. Sounds something could touching both the inside of the barrel and outside of the barrel causing a short, but other than that, not sure.
You might also try adding a ground to the chassis of head unit. Run a wire from a known good ground and screw to outside chassis of head unit.
Back in the 80's we would just run a ground wire from the ignition coil with a small capacitor to the body. That usually worked. Sad to see the problem hasn't been fixed yet.
This worked for my classic Mini with Pioneer HU and new amp....horrible rpm-dependent whine plus rapid clicking when the electric fuel pump was on. Did not happen with previous amp but it died so needed a replacement....which then picked up these noise issues. Might be a poor ground elsewhere but this is an easy fix to save a lot of testing.
Glad your enjoying your car stereo now!
Awesome, fixed my engine noise issue.
A couple of things I'm curious about . (1) I didn't have this problem until I replaced my factory alternator with one from RockAuto . (2) most RCA cables for car audio are twisted pair (differential) style so if your head unit isn't set up for this type output but the amp is you would have no noise rejection in the cable . I bring this up because I can't find any statement for my Kenwood decks output type but my JL amp has differential input . I've tested 3 different amps of differing price range and the JL picks up the most noise .
props for your song selection :)
I did It this way and IT works perfectly . Thanj you!
I did exactly what you and I'm absolutely amazed it worked thankyou for this video help out tremendously
So just any copper wire would do? Also, I'm using RCA cables, would this prevent me from plugging in my RCA cables all the way into their respective jacks? Would I plug in the RCA cables first, *then* wrap the wire around?
How does this work if u don't have the same Rca cables to plug into the cd player all my rca are on there own wires so what should I do just ground the deck it's self
Do you have to start the car To get alternator noise the alternator has to be running. And I won’t make noise until I start it either
My car has a factory amp, no RCA cables, all wire harness. Replaced the radio with new harness. Any ideas?
Thank you!! I hate the RPM whine!
how do you fix it on cars with hi output only
hi, behind my stereo i can't find the amp connection, where i can connect the ground cable?
Bro, I've watched a bunch of videos about this, and yours just makes the most sense. It's not that it's any better, but it just... makes sense.
Anyhow, thanks for the info and the time spent to make the video; I owe you a beers.
My work van is driving me nuts 😝 I’m a try this and I’m going to do the big 3 or 4
I have this problem with my new system!!! But I have factory deck so can I do this to my low high converter instead orrr what you thinking.. somebody please help me with this!??
Thank you so much.
Ive got same thing happening on mine but one speaker stolen and its grounded...now i cant figure out wtf to do!
I just installed speakers, amp and sub to my factory head unit in a 2016 Canyon and had 2 noises. One rpm related and the other just a constant buzz. I moved the amp ground and the rpm noise went away but the constant buzz is still there. Do you have Any idea what I should check now?
No. I’m an amateur lol.
Can you please tell me what did you do with the original ground wire that came with head unit? I'm going through it! new audiopipe amps box and speakers. I cant even cut my radio on it's so hurtful.
I’m still having issues. Got a few other ideas. What a joke.
I will try this my system didn't have whine up until recently
Subbed to both. Ok to use some of your music in the future?
I've got a noise problem with an Alpine CDE 110. It ONLY does it in AM radio mode. It has a whine that starts out low and slowly get higher, then it goes back down. It will continue to repeat this as long as the power is on. It even does it with engine off and switch in ACC. Any suggestions of what might be causing this?
did you figure it out?
@@senarain337 No, but I may check around some audio stores to see if there are any filters that may take care of this. Many years ago filters were common.
I don’t wanna take the radio out can I just loop it around on the amp??
Brother am going thru this shit right now, have an 2002 ford Ranger Edge 4dr. And ever since I replaced my head unit from single din. Pioneer, to a double din full screen J.V.C.mc750bt, and added a Kenwood 450 4ch amp for new 6x8 door speakers, to my system. It's killing me, already did the big-3 wires to the engine bay. Plus new 2 pair 3x shielded rca to all 3x amps, I dobt know what to do.......?
I've had at least 4 different mids and highs amps,this last time I swapped a fosgate for a d4s jp95 and the wine drives me insane...and I do not understand why..I'll have to try this
Hey bro did it end up working for u?
The grounding of the head unit case to the closest stable ground should do the same. Some amps are designed so that each rca must remain isolated at input and most certainly at output. When experiencing stereo interference, it will more than likely be ground induced.
I do car audio for a living. Sound like a bad RCA, maybe a small break in the line. But hey, this beats having to pull all that out to replace. Sometimes bad spark plug wires will pick up transit noise and amplify it the rca’s and you will hear it in the audio when the car is running.
The wiring harness was bad. I put in a Pioneer DEH and couldn’t be happier.
late response but I just got a new JVC aftermarket radio and installed it. I don't have my door speakers or tweeters hooked up to an external amplifier, just the deck. I got it all wired and when I fired the car up, as soon as the radio starts, a loud static/screeching sound plays through my mids and tweets. The tweeters get no music just static, the mids get music and static. I am curious if I should cut the car harness's factory ground wire that is running to the headunit and run a NEW & seperate wire from the headunit to the amplifer's ground? Or should I keep the cars factory harness's ground wire and run a secondary ground wire from the chassis of the headunit to the amplifer? Another question is should i use the radios harness black wire (the ground) to run a new wire to a new ground location or should I just connect it to the radio's chassis and run it to a new ground location? Hard to explain but sounds like I'm riding inside a UFO.
Never cut your stock harness. Its always best to run a new ground wire for the new aftermarket headunit. The stock harness ground wire always gave me problems.
A Perfect Circle👍
I didn't work for me but I gave it a try though, I'm getting a ground loop isolator next
Same here. I’m about to order one as well. Did it fix your problem??
You can ground those RCA outputs inside the radio, they all share the same ground pin inside, just solder that pin to the radio chassis and Voila! No more ugly wicked copper wire
Is there a video showing this?
@@cameroncampbell6931 I also would like to see how that works
I had Zero engine noise with my 4 channel Amp and then I added the Subwoofer amp and started getting noise of my 4 channel amp speakers. I couldn't use the same ground I used for the 4 channel amp but it's pretty much comming from the same piece. Any clue what it could be?
Thanks
I’m having the EXACT same problem after adding my four channel amp. Lmk what helps you plz
@@cameroncampbell6931 There's a bunch of videos here on how to fix this issue but I ended up getting some descent tight fitting RCA's and that fixed it.
@@imatter4619 It ended up being a difference in ground between the two amplifiers. I bought two ground loop isolators for the four channel amp and it took the static away
.....is it still quiet after you start the engine?
Remove the serpentine belt and run the car with the stereo on. Do you still have the noise? I'm thinking you're getting electrical interference from your ignition wires plugs and mistaking it for an alternator whine. Wonder what's going on. My dad has the same issue with his mustang and I looked at it for like 20 minutes. I went to college for automotive and took an audio class and that doesn't sound like ground loop. Ground loop is like a hollow sound.
So new wires?
I’m having the same issue as he is. What do I do to fix it?
Thank u. I'm looking for fix didn't start this tell I put this new system in
Dude you a lifesaver and I’m not talking about candy...lol
Bro. Try running output of rf from transistorized radios. Ooof talking needing ground straps at the doors, frame, radio, it is insane how much bonding and grounding is required. Insane.
does your after market kenwood radio using after market bracket which is Plastic/abs ?? and the factory brakcet is metal ??
if so then maybe that's the problem. the bracket should be attached to the frame inside the dash which is ground for it.
FineTune it went back to garbage, so I’ll look into that thank you. I’m also going to run a ground directly off the battery back to stereo and amp.
@@Teamcurtisbjj Ah sorry to hear that. Ignore my question above then. Cheers
I have to try this. Unfortunately and im thinking it just might work
Dude, they make terminating caps to to cover those rca connecters. No more emf noise from those open ports. they are about $10 for 8 on Amazon.
I’m having the same problem as he is but never heard of terminating caps. What do they do and can you drop a link to find what you’re talking about? Thank you
I'm about to try this on my un-used amp rca ports. I think it's my issue.
Well when you run into these issues you isolate segments and run them stand alone with temporary wiring attached to the same automobile. Also known as base lining. One component at a time.
I just paid a company to see if they can fix the problem for me they charge me $360 for one full day they couldn’t figure it out I will have to try this
Tried this, didn’t work unfortunately. My mechanic put his “stethoscope” to the alternator and it turns out it’s no good. I still have the factory new unit from 2007 in my highlander. The whine when you listen to it sounds the exact same as what’s coming through my speakers. At least my radio unit is very grounded now. Didn’t have any whine when the engine was off which was a big clue.
I replaced a Bosch Multimedia Compact with a Android 12 Head Unit. Works great except that the radio has a slight "crack". Seems to be not related to induction noise. Sometimes the crack is not there. So has to do with antenna I guess. Annoying. Old radio did not have this.
A Perfect Circle !!!!!!!!!!!!!!!!! 🤘🤘🤘🤘👌👌👌
Nice job 😂
I’ve tore my system apart about 10 times now. Today I took my radio out and took the ground from the radio to the chassis where my amps are grounded and still nothing.
I have a stock radio that I tapped into with an LOC to get signal to go to my amps. I wonder if I just wrap wires around the input/output of the LOC if that’ll have the same effect on my whine issue?
I’m gonna have to try it.
Tha KS brother man im about to do this lol
Mine never really got louder with acceleration or anything it was just a constant humming noise. Mine was because I grounded my amp to my 2nd battery so I just re grounded it to the frame where my back seats are and it stopped. Prob a noob mistake lol
People forget to bypass factory amp just have to unplugged it usually the bigger one if the two if your using factory speaker wires keep the small one on. If you ran fresh speaker wires to the aftermarket amp unplugged everything on the factory amp
Hey man I'm going to feel just like u tomorrow after spending 1600 on a stereo sound system .... It's common on accords
Hey man how did you fix it ? I have rockville db55 amp hooked up with my factory stereo but the noise won’t go away. I earlier had kicker cx600.1 even then the noise was there. Everything is grounded properly but can’t figure out how to fix it.
Holy fuck. Thank you man🤩
Imma have to do this cause I have blown 2 amps so far running all my music and its a loud as hell whine no matter what and gets worse when you drive. I hope this works.
Did it work?
@@ajpadilla1603 sadly no, I also went and bought a new head unit, new amps and still nothing. Even a new cap so I think its a deeper issue with what I am having but simply no. Thats me tho.
If this works on my pioneer I owe you a drink.
Lemme know. It’s interesting to see how it’s working for a lot of viewers!
Dno wat u taking about coz that trick does work
3:08 the look of “ I can’t believe this shit “
If I fix the problem I will be like you
my jvc does that too
Is that wire insulated
Ground wires done have to be insulated dude, from electrical theory it just doesn’t, but it can be insulated not saying it’ll make any major diff just it’s insulated but ground is just somewhere for an inrush of current to go to Incase something makes the car produce to much power or having s blowout on a speaker or the system
Team Curtis BJJ ʕ •ᴥ•ʔ
Did the issue return after you did this?
Yes. Still stuck with the shit sound.
Wow so it didn’t fix it in the long run? I just got a 4 channel amp and tweeters “professionally” installed and boom instant buzzing and engine whine. I’m so pissed about it
What's that last song? Good video
Michal R last song is from a band I was in called The Up. The song is called Rewind Me. I’ll upload it to this channel.
@@Teamcurtisbjj impressive man, sounded good
You said it made a noise with the car running.I didn't here you start your engine.All that show's is you didn't have a good ground.
I have this shitty ass problem to when i put my key in the acc position my shit sounds great but when i put it in the on position i hear a loud ringing also when i start my cAr and rev it i can also hear the rpms whine through my speakers i need help 😭😭😭
I’m going to run a ground directly to the negative terminal. I’ve messed with the ground on the amp 10 times. I’m thing it’s gotta be the deck.
Its just sad putting grand after grand into this shit and having these proplems
It didn't work on my case. Thanks
The hum and distortion comes back this doesnt fix it
it does not work as well
I tried it and it didn't work 🙄😭
Update. It’s the fucking faceplate connection. I don’t know how to fix it.
I just tried this and didn't work for me..
Same with me. What worked for u?
@@brycemcmullen4828 for me too, but i nie must try add ground to car body
I did this and it took it away for like 5 minutes but then it came back
Anthony Barragan yep. Same for me.
ActualTour V2.0 I feel like we didn’t ground it right did you screw it down under the screw? I just left the side on top of them screw maybe the vibrations of the car keep it from being stabilized?
Same problem came back to me too - back to the drawing board
This is the 3rd different way I've seen it done.
Did that ever work in the end for you ?
No won’t work for me
For about two days.
Start the engine
I bought a fucking new alternator and swaped it out.... wish I knew that earlier.... will give it a try....
i fixed my alternator noise by eliminating the headunit chassis ground, making sure it touches no metal at all
I’ll give that a try!
🤣that is the true broo
too bad i don’t have an aftermarket stereo with rca 😂😂
Start the car after the fix!!!
i swear to god if this works
Keep us updated…
@@Teamcurtisbjj tbh with ya i didnt even try it yet a year later i probably got lazy but im gonna get wire for this right now and do it. same car same stereo and everything just been putting up with it lol. hopped back in and rewired everything today and its still there... gonna try it now.
it still makes a horrible sound, oh... it´s the music,
😂😂😂😂😂 No way that actually worked, the Engine wasn't even running. Yet another Fakebook fix.... This is almost as good as those Omega 40KRMS subwoofers with 0 ohm voicecoils.
🤣🤣🤣🤣🤣👌
Hummm no engine running so you won’t hear it lol
For me it just made it louder and worse :(
Have you fix it ?
@@gonzalezbeast2286 I gave up after a few weeks lol tried everything, even changed the alternator but still same issue, it looks like that power regulator from alternator is causing that issue but filter for it is too expensive so fk it
@@cykablyat8063 try putting your ground in a seat bolt
Fake, you didn’t start the car. You can’t get alternator whine unless the alternator is running now I have heard of this working but in your case you’re not being honest.
It didn't even sound like you started your car with your car even running? And who's this embarrassing to I don't understand what's embarrassing and who would it be embarrassing to who installed your system?
This is just a case of you get what you pay for.
Almost all the new 2020-2022 pioneer and kenwoods have this issue. Its the cheap china chips and hardware. My 2022 pioneer avh-240ex puts out garbage quality sound, even with a 5 channel fosgate amp. Full on regret the purchase.
My Pioneer is working flawlessly. Very happy with it… it was expensive. Thanks for commenting 👍🏻
