2014. Why are there crackling noises in RF speaker?


You may have a short or open condition in the wire/cable connecting the two. Especially the ground connection, if it gets disconnected, the the main signal wire will pick up every stray electric/electronic noise near the wire.

I have a 2009 BMW X5 and its making a crackling noise in the engine. When I accelerate it goes away but is present when the vehicle is stopped or at low speeds. Please help


The crackling sound you hear is called pre-ignition. Meaning your either running too cheap a fuel or the engine needs timing reset because timing is too far advanced and causing pre-ignition. That means the spark plugs are firing earlier than they should.

I tried to install an aftermarket 6 1/2" speaker


possible reasons:

Impedance mismatch
wiring is grounding out on frame/metal
speaker isn't OEM and is slightly "pinched" thus causing cone distortion

One of these three will be your issue.

Also, you may remove the speaker and leave it hanging with the wires attached. Knowing that no wiring is shorted and nothing is disturbing the cone, try running your stereo. Same crackling problem? It may be an impedance issue or you reversed the polarity on your speaker.

It will require some work but the solution is there if it was working before.

Hi all My rpm runs unusually high when i start my car in the morning plus I hear an embarassing crackling sound when I accelerate in low gear. But once it's in high speed the sound stops. Joshua


1- The problem in the high idel at first start could be the TPS "throtal Posistion Sensior" is going bad. I'd take it to your mecanic and ask him to take a quick listen most gareages wont charge just to listen to it real quick.

2- is this a crackling noise? OR is it a vibrating noise could be a heat shild, the weld could have broke off on one side causeing a viabration.wont affect the car just will be anoing...God luck

My speakers will start to make a crackling sort of noise then stop. Sometimes the radio will not play at all. Sometimes the speakes make this crackling noise then they stop making the noise and play ok for...


Are your speakers factory? Sometimes the wires start corroding from moistures or from not being covered well. If you can or know someone who can, you may try checking the wires to the speakers/radio. If they are corroding, they may be shorting out.
