Interior Whine when Accelerating
In my 98 SE, I just noticed what sounds like alternator whine coming over the front speakers (with the stereo off). The problem is this only happens under a load when the car is accelerating, not cruising or idle. Go up a hill, there is the noise. Pass a car, there is the noise. Does anyone know what this may be? Please help.
Thanks,
Jeff

Would it be the Electronic engine motor mounts ? Does the problem go away after a few seconds?

Check the connection to the antena behind your radio may be loose, dirty or touching ground. If it continues and you are sure the sound is coming from the speakers you might want to install a ground loop isolator (it goes between the antena connection and the radio) there's another isolator that you can use on your rca's... but can't remember the name.
Not sure if this will help since everything you have is stock, i've never experienced that sound with factory radio only after market.......post up in the audio forum, maybe one of the guys there can better assist you.

Mine makes the same noise, but I bought the ebay supercharger sound noise. Its a little box that you plug into your tach wire that goes to your audio so when you rev ur engine it screams like a supercharger. +70hp.
j/k
I second this, mine always had a while almost like the one described. It was actually due to a shoddy install of an aftermarket deck by the previous owner. The antenna wasn't plugged in all the way And there was a wire that was partly exposed that was wrapped poorly in electrical tape up against it.
As far as the antenna being grounded though, I don't think that would cause any problems because it is grounded as is. To my knowledge the factory wiring harness has no spot for ground. The stock setup grounds through the casing and/or antenna. With my aftermarket deck there was no ground through the case, so my only ground actually was plugging the antenna in.

When ever I'm listening to my ipod at low volume or inbetween songs I hear a high pitch whine very faint and its proportional to engine speed, everyone who rides with me is like, "dude do you turbo?!" which makes good for jokes when I'm like turbo baby! and floor it and its like whineeeee whineeee
Here's a quote on the subject from another forum: "What you're hearing is alternator whine. The frontend of the amp in your tunes is reacting to dirty power and passing it through to your speakers."
So the culprit is a ground loop, which can be fixed easily. Head over to radioshack. It doesn't bother me, I think its hilarious.
