hey guys anyone else have an issue with a very but faint high frequency noise coming out of the speakers when you accelerate? its driving me mad when i just wish to enjoy the road with no music on. i've tried to troubleshoot but i cant come up with any solutions.

 

Sounds like ground loop whine. Are you using an MP3 player with the RCA inputs and charging/powering the MP3 player with the 12v accessory/cig lighter port?
If so, try not charging at the same time or install a ground loop isolator.
That's all I can suggest...

 

i use the ipod and am connected through the dealer's ipod cable. do they make a ground loop isolator for that connection? thanks!

 

I know of no such specific isolator, shouldn't need one either.
If your only using an Ipod with the factory cabling, nothing else/aftermarket hooked up at all, I'd say take it in for a warranty issue. Do you know if it only happens when using the Ipod?

I use a classic, and have no high pitched sounds or any other sounds that don't belong at all. I'm very sensitive to those types of noises too, often being the first and sometimes the only person to hear an interference.

 

I have a system installed and I can clearly hear the static noise. I usually have music on so it doesn't bother me. I was told the static comes from the radio.

 

i just disconnected the ipod and still hear it clearly when i press on the gas. so it aint an ipod issue.

 

If you can clearly hear it all the time it should make it easier to replicate for the dealer when you bring it in.

 

Alternator whine? When you sit still and rev the engine, does it get louder and more high pitched with your revs?

 

hey thanks betty. tried that all is quiet in that end. it only shows up in motion.

 

So you've ruled out the alternator. I wouldn't think that would be it on a new car with no aftermarket equipment, but you want to rule out everything you know it isn't.

 

Just take it to the dealer. Its obviously some kind of grounding issue they need to fix.

 

i heard it once while using my ipod.. i don't think i was driving though.. i could pause the song and turn the radio all the way up and just hear it

its gone now though

 

Took it to the dealer today and guess what? it didnt do it! grrrrr

 

I've heard of this noise in GM cars. My dad has an Astro Van that does this. It's electronics noise and sounds more apparent when the air conditioner or heater is on, especially from the outside.

 

So after taking a drive and hearing it again and again i took it back to the dealer. They for some reason do not hear what i hear and its extremely frustrating. Either i'm goin nuts or these guys refuse to the high pitch hiss coming out of the speakers. its so bad right now my ears are ringing from it like i was just at a loud concert. anyway i can kill the power to the speakers till i resolve this issue?
