Hey guys,

I'm hoping somebody can help me with this. Today I took out the Avic-Z2 which goes into the aux-input of the PXI-H990. I don't remember if I had popping noises before (I don't think I did) but I do now, it has turn ignition on pop, turn car off pop, and even change song pop along with pause song pop.

Can this be caused by the head unit? From what I remember people usually blame it on power wire and RCA being close together but can it be something with the head unit and if so what?

Thanks

Sounds like , as an electrical contact is made you are getting a rush of power to your speakers.

Some amps are known to have turn and turn off issues.
