-Weird sound from the rear end. *Not sure*. - United Bimmer Community

I was driving back home. It was night time and I didn’t switch on the AC. My two rear speakers make some “Popping sound” and I know it needs replacing since its crack. It’s an OEM Nokia speaker.

I was playing a loud music. The popping sound from the speaker is unnoticeable. Suddenly there was a loud noise. I can’t describe where the noise came from but it’s like this “ TAT TAT TAT TAT TAT ”. I thought at first it was the music but it’s getting louder and off the radio and stop at the bus stand. The sound appears for 10 seconds and gone like that. Then I drive it again without switching on the radio. It’s all ok till I reach home. Felling not satisfied I drive another 15 minutes at the freeway at 120km/hr and all seems fine. All ok!! Make a U turn and switch on the radio and I can only hear a slight “popping sound” like I always hear.

So can anybody tell me what’s gone wrong here? Is it the speakers?

did you feel anything when it happened? did the car feel rough or vibrate or anything?

No vibration at all. The engine runs like normal when the sound occurs.

Hmm..I guess could be the radio speakers?

Maybe you just got hit by an RF or EMI pulse . . Lots of things can interfere with a radio signal . . welders for example. Were you near a construction site?

you don't happen to have a nextel phone near the radio or amp did you. Those things make all my electronics pop. So much radiation.

I drive today at the highway. No noise except for the slight popping sound in the rear speakers which I hear everyday and now it starts popping in the driver side speaker. I wonder what happen because yesterday that speaker (Driver side speaker) is good.

I don’t think it anything to do with signal interferences. Yes I do have the Sony Tripod Head unit. It’s an old model. The yesterday's loud sound it like the sound of something loses.
