    Low level intermittent static

    A new noise just started occuring in my system.

    It's a low level intermittent electronic static/buzzing sound which seems to get worse when driving over rough patches / suspension jolts.

    It only occurs with the engine running. It goes away completely by turning the HU volume down to 0. So I believe it is either originating in the HU (Alpine X008U) or maybe originating in the Idatalink Maestro RR or PAC TR1 which supply/control power to the headunit. Maybe a loose or failing component?`

    Anybody else have experience this type of issue?

    That's probably going to be one of those issues requiring old fashioned troubleshooting time. I would agree that the mute does indicate HU or IDLink. Does any component downstream also mute upon no signal from head unit? Make sure before ruling out those components. Then begin thoroughly checking each connection and wire.

    try simplifying first: if you can unplug the idatalink and/or PAC device, then see if you can reproduce it.

    Re: Low level intermittent static

    So this noise has completely disappeared on it's own

    Only thing that changed is that I charged the vehicle battery. I don't use an aux battery - just the one under the hood. It is a X2 Power size 24F dual purpose (starting, deep cycle) 76Ah AGM. I performed a couple 20min tuning sessions and thought I should put it on the charger. It took 25 Ah.

    Will make sure I use the power supply in the future for any tuning over 10min.

    best part about problems that go away on their own? come back on their own?

    Bad ground somewhere, it doesn't necessarily have to be an audio component ground, either.

    batteries help to filter noise, but only when they are healthy and well charged. So the noise was probably getting through because your battery wasn't charged.
