Music problem

[Bellyandcaz]

Hi guys.
2006 9-3 wagon.
My stereo has been working fine but the other day the center dash speaker has just started with a high pitch chirping. It’s not a blown speaker, It sounds like siginal issue. No water damage or other problems. I was hammering the player on Saturday and Sunday it’s chirping Morse code from the center speaker.
Could this be a problem with the amp under the seat ??

It could be, but if it is an actual signal noise, it could be coming from a control module. Before you go chasing after phantom noises, pull the neg. battery cable to reset everything and see if the noise goes away.
