Help! I have a humming noise coming from my right front speaker and it turns into a higher pitched whine the harder I accelerate. The speakers in my doors are all pioneers and I checked the connections at the amp, the speaker itself and in the dash at the head unit. I have no idea what is causing the wine/humming noise. Any suggestions?

 

Its most likely your ground. Or if your speaker has a tweeter that may have gone out. Mine did that and I had the same problem, then i took it to a local audio store and the checked it for me and told me it was the ground. You may have a split in your wiring somewhere where its touching metal too....

is this what it is doing?

 

well the speaker is only a few weeks old so it might be the ground and not the tweeter hopefully. Also when i tried to load your video it said the content was unavailable.

 

Thats what mine was too. It was only a month old and my tweeter went out on it. Stupid facebook will only let friends see it i guess. Also check your speaker wire plugging into your amp. If any of those are some what lose and not tightly clamped it can cause that. Does your speaker make that noise with the car off or only when you drive?

 

make sure your power wire is not running within 18" of your rca's if so run your rca's on one side of the truck and the power wire on the other side. the reason being is the pwer wire makes noise from the alternator and the rca is a input signal device and if it see that noise it will be induced into the system, also take a vom set to ohm's put one lead on the neg.side of the battery and the other lead find a good ground point in the back to make your ground make sue you get the the ohms closest to zero as you can. also you can run a wire from your radio ground to your amp ground that keeps your system from seeing mutli.ground points. hope this helps you out.

 

Its only when I drive and it gets worse as I'm accelerating and hitting higher RPM's. If i turn the head unit to standby though the humming noise will stop so I'm thinking it's either the ground or a loose connection. I'll go back and double check all of my connections.

 

I never thought of that but my power cord runs on the opposite side of my truck as my RCA's but they could overlap by the amps where i have extra. I'll also check that.

 

As long as they're not together for more than like 6" your okay. But I had the same problem and it was caused by a bad ground on my amplifier and a set of bad rca's.

 

I did have an overlapping cable back by the amp so i moved it and the noise seems to have gotten much quieter now. I guess its either a bad RCA, or a connection problem then.

 

Sounds like a ground loop somewhere. This may sound crazy but grounding the negative for the RCAs helps eliminate excess noise. I did this in a Mini Cooper S, had Alpine PDX amps, 4.150, and the whine totally went away.

 

What he said^. Grounding the rca's should fix it, or a nice high quality pair would probably fix it too, just remember you get what you pay for.

 

grounding the rca some times help, that why you also make all your grounds at one point to prevent a ground loop. remember current flows from neg. to pos. your pos.wires are connected at the same point keeping your grounds at the same point will eliminate multiple ground paths.

 

So as long as I ground both of my amps at the same point I will prevent the ground loop of the current?

 

On paper, yes. But realistically, it probably won't make the difference.
