I have a weird whining noise coming out of my rear door speaker behind the driver. It sounds like a light whining noise that gets louder when i gas the car. Is it a ground? Wire? any ideas...

was going to ask the same thing; aftermarket stereo, amp, etc?

Does it do it when you play FM, CD, IPOD, etc, or only during one of those?

Typically I would just say its the ground on an amplifier or some cheap RCA Cables, but we're unclear about your stereo setup.

Did you recently get anything done to the vehicle?

sounds like something is loose or an inadequately sized ground wire.

Your Ground wire size should be the same size as the positive wire and be no longer than 3' in length. It should be grounded to the chassis if possible, or an existing larger bolt (i.e. seatbelt or seat mount bolt). I'd start with checking that.

Now, the other root cause could be the RCA jacks. One might be loose, or crushed under the carpeting, or ran too close to the power wire. Or, they just might be inexpensive cables that have no real solid sound interference protection, etc.

I think that's about it?
