On / off through speaker sound

Post by MikkelMuis »

Hi there

I have a question about a weird noise coming from, (Mostly sounds like the rear speakers).

It's almost like when you switch a AMPLIFIER on or off, that initial thump sound you hear when your speakers get current.

This happens when i open a door, you will hear it almost instantly upon opening the doors. And then again a little bit later. Maybe couple on seconds later (like 20seconds)
I have no extra audio devices connected other than what it came out with.

So no amps, no converters or anything like that.

Could someone please assist me with either an explanation or theory?

Just need to make sure that I don't hurt, damage or blow something up because I could have prevented it.

Noticed it happened the 1st time 4 days ago.

Need assistance please...
