i cooked my sub from the humming when i turned it loud and so i switched it with the one i was using as a reflex speaker and then did this trick and omg it was so quiet i thought the sub was off till the bass hit because i was so used to the annoying hum that i tried so hard to fix then just gave up and said fuck it. ty so much for posting this vid!!!
I was hooking up a speaker with the radio on. Positive grounded to body. Not good. Terrible noises after that when ignition on or car running . Replaced 4 channel amp. Same problems. Tried different rca cables still no good. Re did my grounds. No help. This video fixed my problems. And saved my exeleron DVD player. Thank you for your input. 🙂
I have been trying to fix this whine for over a year now and I try this stupid trick today and it fuckin works. I’m excited, but pissed at the same time. Thanks dude.
@@narkyt4356 no. It did not work. The issue lies with the rca cables being too close to electrical system of the vehicle. I ended up coughing up the money for knukoncepts triple shielded cables. The issue is GONE! Ground loop isolator didn't work either. FYI. Peace.
@@narkyt4356 for the rca cables I bought Knuconcepts crystal cables. The rca cables are for the amp. If your having buzzing sounds and you don't run an amplifier with rca cables, than you've got a ground issue. Find a better ground location. Let me know what's up. Thanks www.knukonceptz.com/mobile-audio/rca-cables/krystal-rca-kables/sp/krystal-kable-4-channel-4m-twisted-pair-rca-cable/
YOU ARE JUST MASKING THE PROBLEM. You will be grounding your NEG speaker terminal to CHASSIS GROUND. This is not advisable. The amp will try and ground itself through your RCAs. This is true on ALL half bridge sub amps. The RCA terminal shield(outside metal) is directly connected to NEG speaker terminal inside the amplifier. How do I know this..... I work on amps for a living.
Sounds like you have a bad ground somewhere. Instead of getto fixing it I would have spent the time to figure out what the actual cause was. But to each their own.
not only that but tape the sides of the actual stereo itself with electrical tape sometimes the metal on metal can cause audio interference due to grounding issues.
The upside down "U" you see, right next to the RCA plugs, on the chassis IS the OEM ground wire outlet. You just a male clip on it and ground it, dude.
I just used this technique with success. I had a horrible whine feedback from the engine. My head unit had 3 outputs for front, rear, and subwoofer. I am using the rear and subwoofer outputs and just grounded the 'front' output and now I have absolutely no feedback. Thanks for the video.
I know I'm late to party but you shouldn't stop at grounding to the stereo, continue to run that wire and ground to the car chassis, chances are that there is an exposed bolt in the stereo dash area that you can terminate that wire and ground
@@wavyybased1820 Yes, the proper way to ground a head-unit is to use a 8" to 10" length of 16 to 18 AWG OFC wire with two small ring terminals. One end is connected to a screw of choice that contacts to the metal chassis on the backside of the head-unit & the other end is connected to the metal dashboard mount that the head-unit gets mounted to.
Main route cause of buzzing is running your power cable back to the amplifiers along with the RCA's, which is a no no, RCA's should be run on the separate side of the car to avoid interference between the two styles of cables. Power cable will mess with audio signals of the RCA jacks., it's pretty much a ground issue, but this hack is dumb, the issue is not the deck, it's somewhere else. P.S. another cause if hear "whine or buzzing noises" its due to your alternator and another ground issue.
Okay guys these things he's showing you work but in the end you've still got a problem somewhere in the system!! I've seen everything from battery not connected good to bad battery or a bad speaker or bad ground on an amplifier or you hooked RCA's up while the head unit is playing that usually does not bother it LOL what I found with my system was I had a bad diode in the alternator LOL and that bad diode can kill a battery!! So I would say have the alternator checked first and check the battery second if those do not remedy your problem make sure all of your grounds are properly grounded to a good frame ground!! Usually that wine is caused by either the alternator or battery or a bad ground grounding the RCA's is a quick fix but should only be a temporary fix there's still an underlying problem!! So if you're running a big system you need to find the correct issue and correct the problem instead of doing this because in the end you will mess up more equipment!!! Keep jamming hard keep kicking it LOL just remember that wine tells you there's something wrong other than just grounded RCA's!!!
You probably need the other kind of rcas there are two different types made specifically for each type of amp every amp either takes one or the other look it up to test your amp tovfind our what one u need look up a video on the two types of rcas
I just installed speakers, amp and sub to my factory head unit with an LOC 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?
i did that but the problem is still there.the noise was a pulsating one like "THUP THUP THUP THUP" when i unplug the RCA cables the noise was gone even the GAIN knob was set to maximum. ther problem is there even when the engine is off. change the RCA cables dozen of times , change the grounding wire and location multiple times no solution al all. ANY IDEA WHAT CAUSE THE PROBLEM?
This made it even louder lol my problem is I hear the engine noise and everything coming through my speakers I put the ground on the deck to a different location that didn't solve it
Check your ground coming off your amps take it off and grind it down too bare metal again. Dont use a self tapper drill a hole and use a threaded bolt ,nut and lock washer.
Do you think I could ground the RCA cable at the amp? It shouldn't matter whether I do it at the stereo or the amp, they are connected right? I don't want to pull the deck, it's a pain in the ass to pull.
Worked for me. Thanks a lot buddy. Why the hell wouldn't the radio makers just do this for you? It would have saved me the trouble of having to remove my radio twice. Fucking assholes!
90% of the time its your ground coming out of your amp doesn't match the gauge wire going in. That loop has to be the same. I've seen 4 gauge going in and 10-18 gauge going out to the ground. That will never work. U can use a noise stopping block, but that's only hiding some of the noise, its not getting rid of the problem. Good luck with this method. Lol
@Sound Speeds 2.5mm to 3.5mm adapter connected to headset of phone , then to 3.5mm to 1/4 phono (,mono) then inserted to mixer using aux send and mic input,, ,, dial does not hum but when you try to dial a number, a loud humming comes up,,, how do I fix this ?
You should not do this the RCA's are already grounded! Either you have a buzz from blowing an internal fuse on the head unit from hooking up or unhooking your RCA's while the head unit was powered up, or you have a whine which could be a bad head unit ground, bad amp ground, bad battery, bad RCA's, bad battery connections either loose or connected, or maybe even a shorted speaker wire.
someone said if i change my stereo to a better/newer one then it would fix problem u think it will? my subs hum when volumes turned off or low and it sounds distorted and stereo whines when the engine rpms go up
Good video but professionals won't do this trick. Not all alternator whinning is caused by a bad ground but this can work for some but not for everyone. The hum is caused by the power wire to the head unit from the ecu unfortunately. An inline Alternator to Battery Noise Filter eliminates everything but is costly for that part. $180 before tax
I was thinking the same thing--intro audio we deal with ground loops quite often... it all comes down to different grounding points within the same circuit... I didn't think you would have the same problem with noise from ground loops in a car installation.. you just don't have multiple points to ground--it's one car, 1 chassis afterall. engine noise, other electrical noise could be introduced through cheap RCA cables. Use 75-ohm coaxial cables with quality RCA connectors should take care of most noise...isolate the audio cables from the power cables (either by routing them separately or physically shielding them in some conduit or tape etc. I don't think the problem is with the grounding of the head unit-but it is the point in the signal chain in which noise that has made its way into the cabling from somewhere else will make itself heard... so although this may seem to solve the problem, it's really only putting a Band-Aid on it and not actually stopping noise ingress. it's kind of like adding a noise filter for RF interference..
@@nickloss2377 its not a ground loop hum, its a power hum. We identified the issue on the vehicle after a shady install was done and we tried to fix the issue which was in the electrical throughout the vehicle from the computer. None fixable even with a $200+ alternator noise filter, big 4 upgrades and a lot more.
this is not a fix. this is more like a "masking" the problem, you just NEED to make solid connections of all your grounds.. this "solution" is not the right thing to do, cause the problem is is there and not resolved.
Burni cause rca wires has audio signals in them, if you ground it with chassis ground, you’re gonna introduce conflict aka alternator whine, power noise, ect within the signals, there’s a - and a + of the connections on a rca.. which is the outer part is the - and the inner part is the + And both can only be connected to the inputs/outputs of the radio/amplifier(s).. Just dont do what this person did, instead just make sure all your grounds are solid(battery, alternator, amplifier, radio) and so on. Just dont ground your rca.. never.
