[brianbelch]

yeah in wrong thread

[Quashish]

oh ok. wrong section.

try tuning the amp, i dont know what knob it it but if its up too high you get that low white noise rumble. is that what you mean?

I Would Say Check All Gounds On Amp An Adjust Eq Settings On Ipod
Or Check Your Aux/usb Cabble.

[Quashish]

these are the knobs im talking about. im not sure what your amp has.

Adjust Eq Settings On Ipod
Or Check Your Aux/usb Cabble.

and since when do i pods have an EQ??

As previously stated, ensure that the head unit and the subwoofer are both properly grounded... If your ipod is running through the aux input on your head unit and plugged in for power via the cigarette lighter, verify that both of those are grounded to the same point. I had that issue with my unit because the ground on the head unit and the ground on the cigarette lighter were not both grounded to the chassis, and just changing the ground so that they were the same removed the feedback.

^^^ What he said. It's your grounds.

I get the same whining sound. I notice that it goes away when I use a new cord to plug in the ipod to the headunit. Sometimes the wires inside start to separate and this can cause problems. Even, lose the signal to certain speakers.

[SPLCB7]

its probably a bad ground and or your ipod cord....if you run power wires next to your rca's that causes said problems too always run your rca's and power wires on opposite sides of the car.

[brianbelch]

its deff the cig lighter ground cuz it only happens when its charging through that. gonna tackle this today but grounding both the cd player and the cig lighter to the chasis if im correct.

What you are experiencing most likely is a ground loop, or ground offset issue.

A few searches from the info you find on that page/thread and you should be good .
