Because OEM sux.
Look for bad or shorting speaker connections or wires.

List brands and models.I'm having the EXACT same issues. Started just by a couple seconds of popping then the deck just not working. Now the deck stops immediately as I start the car, crackling and popping don't stop until car is shut off, locked, and interior lights dim. I also have a 3200w amp and a massive sub so it's a nightmare and i'm sure i'll get no assistance from ford because the aftermarket sound system.
You have noises from the speakers with the key off?
That is a different creature indeed man. let me see if I can get a hold of someone for you from ford service.
Thanks for reaching out, freemind!...Plus I just sent a PM to look at this thread/issue
Hi JWhite09,Thanks a million freemind!! I sent a PM as well...
Haven't had a chance to get on in a few days. Just got Meagan's message and tickled that she PM'd me so quick[woot]. Hopefully she can continue to help me solve this problem.You RAWK Meagan
The radio shouldnt even be getting power, the only thing that should have any power is the clock. The amp or any thing else in the unit should not be receiving any power after the car is off.So was Meagan able to resolve the issue?
If not, it sounds to me like a head unit problem for sure.
Clearly your speakers work fine. Your output load (aka your speakers) won't affect how the other speakers sound, that is if one speaker has a bad connection it won't make the others go all rice krispies on you (snap crackle and pop).
However, if something is going wrong in the head unit in terms of signal processing or amplification, that wonky signal may be sent to the speakers and result in the rice krispies effect.
What definitely points to your head unit as the issue is how the popping happens even with the car is off.
Let's break it down:
Case 1: everything is working. You send an input signal (audio, sync instructions, etc) to your headunit. Headunit does what it is supposed to (amplifies sound, alters the audio signal, makes a phone call, whatever) and send s the output to speakers.
Case 2a: rice krispies effect.
you send an input signal to Headunit, the HU does NOT do what it is supposed to do, and the result is an output signal of popping in your speakers.
Case 2b: rice krispies. You DON'T send any input, but the HUthinks you did, messes it up, and makes popping happen.
In conclusion, I think your inputs to your HU are messing up. Since you are able to operate the stereo fine at times, clearly the HU can function as It should.
However, if the input being sent to the HU is wonky, then the HU will do wonky things.
Hi kxweil38,Same issue has happened with me. Lasr year it happened twice. First time was at a gas station. All of the speakers and the sub-woofer started to make a loud thumping sound. Doors were closed and the vehicle was not running. Took it to the dealer and they re-loaded the software. Had not happened until about two weeks ago when it did the same thing and scared my wife, who had no idea what was going on.
You RAWK Meagan
