Car audio FIX! Ground and engine noise solution.

***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).

FOR ANYONE LOOKING FOR COMMENTS ON IF THIS WORKS: I have a Kenwood headunit and the problem was amp wine in my newly installed, bridged kenwood KAC 600w. When I disconnected the SUBWOOFER rca the wine stopped. I was like what? those should be isolated circuits. Well if your problem has to do with the rca induced wining then go check the headunit, unplug one set, replug etc. see what stops the wine. If you disconnect 1 set of rcas and it fixed the wine for the opposite and still connected amp, then this is likely your problem. Wrap the wire around the rca terminals and secure it. Problem solved. Just make sure that the wire you used actually grounds those RCAs to the headunit as said in the description.

IT WORKS!
Thanks to this video I didn't have to call in my dad for help :)

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.

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.

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.

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.

[MrRayDupree]

Glad your enjoying your car stereo now!

[nickalldaylong]

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.

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.

you didnt turn the engine on and rev to test

[michaelburke]

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?

[Mechanixscott]

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.

[curiosity]

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.

[wesleyfrazier]

I did exactly what you and I'm absolutely amazed it worked thankyou for this video help out tremendously

[raiderman]

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.

[NeverMetTheGuy]

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.

[xfrostyyy-ht]

Do yours slightly hiss when tuned off. Mine does

[JONJon-COD]

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

[chadrides]

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.
