Adam Francis, I was getting crazy with my issue, every time I pop up the subwoofer gain way more than a half the hum vibrates my subs so bad, and I just weld a cable to the RCA plug that goes to my mono amp, and boom, no more whine and hum noises, excellent video thanks for the tips, I have already did it to my car stereo, I weld the RCA cables to the chasis it worked but was back again, thanks mate, you deserve these ⭐⭐⭐⭐⭐
Dude I never comment on youtube videos think maybe 3 in my life but I did the wire around rca on amp to ground boom hum I literally rewired almost everything bout to give up untill I stumbled on ya vid can't tell u how much I appreciate I ever subscribe to ya channel thanks again man
Hello... I'm from Mizoram State in the far North Eastern area of India. It's great to hear the way you explained the whole lot, which is just what I've been expecting for the last past couple of years. It's really perfect for my liking. You've brought me success. May the Good Lord bless you always in all your needs.
You're life saver. I have 2amp setup in my car and humming seems to come from sub amp, so I was thinking its broken and was about to buy a new one🤦♂️, will try these fixes first. Cheers
@@cxsper6111 I later found out that issue is rca cables and speaker amp being turned all the way up. I resolve it with jl audio Bluetooth receiver which eliminates need of long rca cables and also gives strong signal so I can turn down amp gain.
This is the best vid on the subject, period. I'm about to crack open a brand new amp for the same fix. Why have manufacturers not figured this out and continue to sell them when clearly there's an issue? Does it have to do with floating ground on the RCA's?
I tried it on mine, it changed the frequency of the hum, but it was still there. I noticed it after I replaced my rear speakers, it was very, very faint, however I bought a small amp .... which amplified it. My car's stereo controls the climate settings, and also the cruise control, I can't really remove the stereo without losing features, so I added a Kicker kisloc2 which is working, but it still amplifies the hum even on the lowest possible gain setting ... People online mentioned the day time running lights will cause a buzz with after market amps, which it did (when the car was both off, and on) I removed the fuse, and the sound went away with car off, however while on it still hums, this was worth the effort to try, I just don't know what to do now, it had some effect but the sound went from one constant tone, to like 3-4 different tones at once oddly enough. Wasn't any quieter, but I really wasn't expecting this to work for me, as I think it's my cars preamp ... beside ferrite rings I'm not sure what to try =/ Guess this is what I get for trying to do something nice for myself, speakers, wiring kit, amp, loc and it's only gotten worse now lol
bro out of most of the videos on youtube about this issue ,you nailed it..simple and direct and not gonna break my bank....no purchase..no software download..lol..easy peasy..and yes this did work..I also have a line out converter..whats your thought on sub jacks..the aux jacks for youe subs i8 ment..do i go standard or braided and does material efect powert?
I have set up an car amplifier for my TV at home. Recently i got noticed a Buzz sound from speakers not from subwoofer. Previously it was not there. I would like to know how your car amplifier had set up for remote cable for "ON" indication. Are you connected with a small wire from 12v to remote. For me it is 12vdc 30A power source. So I used around 20awg wire for this. I don't know this makes anything noise.
Ha I did the same thing years ago with my car amp powered in home, without knowing if it's safe for the amp or any source I'm connecting to it, but I did it anyway since the hum went away completely when connecting the grounds together. So I guess it's safe? Also, do you have any video about the power supply powering your amp? And that thing that you set at 13V? Because I use a PC PSU and as you know that stays at 12V.
Old video, but worth a shot. Would it be possible that the rca port *ground wire* on the amp (witch connects to the board within the amp) could have broken at the soldier point?.. Tried sub, and mids on both channels and always a hum. Until I cut remote power. No power wire crossing rca or speakers. Power straight up driver side and speakers/rca's up passenger side. *wires do not cross* Been playing to long Ready to rip it apart now. Also While I'm writing a story. 😂.. Got a alpine 500 mono block. Powers up, but no sound to tye speakers. Speakers work on different amp.
Hi. How to eliminate hum from a home "hifi" sub, when it probably comes from the power supply transformer? Can I shield the power supply somehow? Thanks.
@@PacmanBasshead hey so I tried this method and it didn't help if anything sounded worse ive messing with this thing for months now and can't figure it out I know there's a way cause I had a guy help me with it once before I uninstalled it when my kids were born but I can't remember what he did I'm running a Alpine IVE-W535HD head unit alpine PDX-M6 amp and 12" alpine type x vehicle is a 2009 saturn vue never had an issue like this till I owned this vehicle and the guy that fixed it said its an issue that has to do with GMC the way they wired the audio systems in here
I tested a 3.5 mm to rca on my amp and it didnt hum but when used with head unit it will hum. Does that mean i need new headunit? I have hook up a rca bass knob too and when i turn the knob up without anything playing, the hum lowers
I was thinking I needed to apply the OLD blown pico ground trick. I have a buzz in a used amp that I bought for a good deal on eBay and i think i might have to try this fix and save $279. I know it is the amp because my first identical amp work fine with my source and power supply. I was told to also test with a battery because power supplies can cause buzzing (according to Rockford Fosgate customer support, but not in my case).
Update it was the old HU. But my RCAs are not in that style they are in a harness. Grounded those and it was good. Time to upgrade the test bench source HU.
I’m using a stock radio with an LC2i loc and my system has a buzzing noise in it. And the whine increases when the rpms increase. Should I wrap wire around the outputs of the LC2i and try to ground them?
any advice on an active sub that makes a hum but only when engine is running. Head unit is a ford 6000CD and bass speaker is an 30 year old tube that had been retired and sitting in my garage and have handed it down to my son :-) Whilst on the subject of the ford 6000CD is it worth changing that out or is it not too bad as a headunit? Thanks in advance. ****UPDATE** changed out the headunit a friend had an aftermarket one and the hum went without changing anything but the headunit and it sounded better so think case solved
I have a NVX 1500 wired up to 2 SDR 12s and when I turn the bass knob up and there's no music its just a quiet hum. Everything is grounded good, power wire is good the 2nd battery is good everything is fine so I'm confused. Is it my RCAs or my LOC? Or maybe the remote wire I'm not sure what the check cause everything works good just annoying might just have to get used to it...
I have a 2005 F-150 Lariat with a stock amp and sub and I can not get rid of the humming after installing an aftermarket radio. I tried grounding the RCAs on the back of the radio and it did not work. I tried grounding the amp wire hardness at the radio, it did not work. My issue is that the amp is wired to the sub with a wire harness, not RCA cables. Any suggestions?
I I have I have a question to ask you what if you're using your stock radio and running the amp to the little converter box to give you the bass because that is what I did to my girlfriend's car I ran the stock radio and the converter and I still get the hum I try several different ground spots but seems like nothing is working I haven't tried your idea yet but I am going to do that but I didn't know if you can do it with the stock radio this is in a 2008 Honda pilot by the way please respond as soon as possible if possible thank you and have a good day
Alright. So I went through the process just like I would for finding a short. disconnect the HU plug. Still noise. 2. disconnect the highs amp power. still. 3. disconnect RCAs from mids and high amps. still. 4. measure V drop of mids amp. fine. 5. disconnect mids ground connection. still. 6. disconnect mids power. still. 7. measure Ohm of all grounds to batt and ground to amp frames. OK. 8. disconnect mids front speaker outputs. still. 9. pull out the front crossovers. disconnect power input. still. 10. disconnect crossover speaker outputs. NOISE STOPS. Ta da. 11. check front speakers for short to ground. OK. 12. reconnect crossover speaker outputs: NOISE RETURNS. 13. Presume interference. Relocate crossover to different positions: TA DA. It turned out that the Morel crossovers are sensitive to interference. They can't be even 8 inches near any power junctions/ECU/etc. So, I relocated them to under the floor carpet in the front where people usually don't put their feet. Noise gone.
Hello, Maybe you can help me find a solution to my subwoofer that is huming. 1. Conected to the amplifier an using CD line input, the sub is huming. Switching to other inputs also hums. Switching to optical or coaxial the hum stops. 2. The subwoofer is conected to the power source and disconected from the amplifier but the other end of the subwoofer cabel is conected to the subwoofer input, the subwoofer is huming. If I take out the cable from the subwoofer, the huming stops. You need to put your ear on the subwoofer and focus to hear very low hum. If I connect again the cable just to the subwoofer input (disconnected from aplifier) the huming reapears. 3. I connected the subwoofer to a different power source and it hums. Please help me with advices.
Most likely because the line input is an unbalanced cable so the humming from its power source is present. Optical and spdif are digital so they are different. Try a ground loop isolator or the second method in this video.
I've found the culprit is my surround amp. Using a car sub amp and pc power supply. Works perfect with rca to phono to phone but get hum and no bass when connecting to surround amoy
I got a stetsom 8k valcan amp and its been makeing that sound form day one ..i tryed grounding the headunit ,,dident work ,,then i grounded the rca on the amp and the subs went crazzy ,,started popping hard ,and the sound was like a cat beeing ran over . I dont want to ground wire it on the inside on the amp ,i will mess it up !..what can i do to make this stop ? It is grounded good to the frame under the car and i tryed grounding it to tje alternator and it still didn't work ...... help please!
@@PacmanBasshead I thought you three methods were going to be.. 1.. kick the headunit over next doors fence. 2.. Frisby the amp over next doors fence. 3.. burn the car and run away. Lolol xx
Subs started humming after installing new head unit I think it's a loose power cord but it could easily be a ground loop. One thing I'll say is when you turn the unit on and the volume is on 0 it hums but when you turn the volume up to 1 and back to 0 the humming immediately stops until you turn the volume back on..weird
Make terrible noise while Running song in car, I think it because of some audio line freq in song, like something in bass I think it can't play the specific sound in song. Please help
In all honesty, I don't know enough about home theatre to give you a good response, try and check continuity between a working home theatre amp RCA shield and ground, if there is ground there then try it on your home amp, however. Be careful. You're playing with much bigger voltages there so unplug and use ppe. Your home amp will also have a ground inside it somewhere. Just as a disclaimer, I have not tried this so am unsure if it works!
Why when I hook my subs into my 300 the constantly hit hard asf with no music playing. The second I hooked eveything and connected my subs to the amp they instantly started hitting hard asf with 0 audio coming from the car itself
I tried this to no avail, but i did notice that the hum is still there after disconnecting both rca cables leading to the head unit. Should i try grounding the cables that lead from the amp to the sub instead?
Absolutely not, thats a fast way to mess everything up. Sounds like your amps power or ground cable has an issue to me. Redo your main ground, or check it.
@PacmanBasshead I redid the ground and connected everything besides the rca cables. Turns out that the hum goes away when I remove the incoming single wire. Maybe the amp is fried?
@markopolo7651 those things are a bitch! Easiest fix for that is to remove the amp from the car entirely, let it discharge overnight, get some 99% isopropyl alcohol and spray it into the switch, toggle it back and forth (literally) 100 times. After 5 mins the alcohol will have evaporated and youll be good to go
Have the common 60hz sub hum from a Klipsch 2.1 Promedia computer speakers. Sound great but built like crap. Annoying as F! Used your basic idea of grounding the controller interface by taking a small wire and looping it around the 12 pin interface on the back of the sub and running it over to one of the screws on the metal backplate. Seemed to work! Thanks!
