I installed an avic n3 a while ago and noticed a little bit ago that i was getting a whinning noise from the front speakers and it is really starting to annoy me. Iv checked all the wires but dont know whats wrong?

Any Help?

Its alternator noise. there is a few remedies for this and if they don't work, chances are that its the unit itself. Pioneer has had problems in the past with this. First question is, how it it hooked into your speakers? what stock system do you have? or are you just running aftermarket amps?

Try finding a better ground for the unit first. If you are using the RCA outputs, try grounding the outer casing of the RCA's also. You can try a ground loop isolator, but 99 times out of a 100 they don't do a damn thing. If that doesn't work let me know and tell me how you are running your interior speakers.

Man you are going to love me. I had the exact same problem and everyone told me it was the pioneer head unit. I rewired everything just to make sure it was the head unit and just when all hopes were lost i drove to a sound car show and some guy wuz there. He told me he could fix it for 45 bucks guaranteed. And me desperate to take the noise out i paid him...

Son of a bitch all he did was put some black electric tape around the rca wires coming out of the head unit. Where the male and female connect just wrap that **** up with black electrical tape.

Now i cant hear any whinning noise at all...

try it hope it helps....

sorry to burst your bubble man, but that won't do ****. Did you actually watch him do it? when I ground the casing of the RCA's like i mentioned before, I wrap it up in electrical tape so it would look like what you just described... maybe thats what you saw??

Yea I even took the stereo out for him and saw him do it... what casing are you talking about? do you mean the rca wires ends?

yea, when you look at the ends of the RCA's there is the pole in the middle and then the ring around the outside, the ring is the ground for the RCA. if you loop a bare wire around that ring and ground it, it usually cancels out the "whine" and to make the wire stay in place around the ring, I use black electrical tape.

Well i have the stock 500 shaker. And all i did was buy the adapter from cruthfield and the avic n3 and hooked it all up like the instructions showed me. I cant really understand waht your saying about the RCA wires, and all the grounding stuff you mentioned. If you have a picture or can explain in more detail that would be great. I d0ont know why i dont understand... i hooked the avic up by myself :/

it could be that you don't understand because you're using the stock speakers and you're not using the RCA jacks at all. The RCA jacks in back of your HU would only be used if you're using an external amp.

Sorry I don't know how to fix your problem though...I would guess that your head unit isn't properly grounded, but I don't know much about that so I can't offer more advice.

The amplifier should be grounded to the chassis of the car, as close to the amp as possible. The head unit should be grounded to the amp's ground connection.
Remember when trying to find engine noise, that electricity follows the path of least resistance, so if you have a nice big juicy ground at the amp, and a shitty amp at the head unit, you will hear noise, which is current flowing through the car to that nice ground. Occasionally, you may have good grounds on the stereo system itself, and have to improve factory grounds elsewhere in the car, such as on the battery, the electric fuel pump, etc.
If you go this route, just work through them one by one, giving the system a listen after improving each ground until you nail it.
Sometimes purchasing a ground loop isolator will fix or reduce engine noise.

if you are running through the factory amps, then the issue is with the car somewhere or the harness that you got to wire it. I would try to reground the engine block to the battery . Leave all the stock wiring in place and run a 4ga wire directly from the negative post on the battery straight to a good spot on the block.

Also, do you have any different spark plug wires on the car? using lower than stock ohm spark plug wires can also cause this kind of interference.

ok so i took it to a shop for them to check it out. And the guys said i needded to bypass the amp to get rid of the whine. And he also said that would kill my bass so i would have to buy a new amp or subs.

Is this guy cheating me or is that the truth?

Its a possibility that thats true.. you could probably eliminate the problem and retain your factory stuff but they would probably charge you a good amt of money to do so in labor just testing and such. I would tell the shop to bypass the amps and then say you want to see how it sounds for a little while. What they may try to do is turn your bass down on your radio to make it sound like **** so you buy subs. Just take it for a day and make sure you re-tune the head unit to sound as good as possible. If you like what you hear, then you just saved some money, if it still sounds like poop, then you may need to add an amp and sub(s)
