Cracking Front Passenger Speaker: NOT a blown speaker
Car Info:
2010 E90 LCI 335d Base Audio CIC iDrive Bavsound Stage 1 Speakers The Issue: My front passenger side door speaker cracks when there is bass-heavy music. It's only that one speaker. This issue was present with the stock speaker as well as the bavsound speaker. I even swapped around the bavsound speakers but the issue persists. The cracking is dependent on bass amount and volume. If the music has little bass but is turned up, the speaker cracks. If it has a lot of bass and is turned down, there is mild cracking. As I turn the volume up the cracking gets worse. If the bass is low and volume is low it won't crack(or at least it isn't totally obvious) and I can enjoy my music This issue is independent of the door. I held the speaker in my hand with the door card off and it still cracked. The kicker here is I have tried installing and uninstalling an Avin iDrive unit, and have had to pull the head unit as well as the idrive screen about 3 times. I'm thinking one of those times I just didn't fully seat a connection and that's why this issue appears. Anyone have any ideas about where to look for broken wires, bad connections, or similar? I'm hoping since it's only limited to the passenger door speaker and nothing else it shouldn't be a huge problem. P.S. When people say "head unit", is that the iDrive screen, or is it the box where those preset buttons and CD player are? This has always confused me. Last edited by Torqu3; 02-06-2018 at 10:54 AM.. |

Often a hard cracking sound will be due to a connection point that is too weak to carry the power to the speaker. The crack sound occurs when the connection goes out then quickly comes back in play.
Sounds like it's time to start tracing wires. |

"Base audio" I thought was the normal way to describe it. 2 front door speakers, 2 rear shelf speakers, 2 underseat subwoofers, no amplifier.

You are correct I didn't read carefully before
opening my mouth. Are you turning it up a lot before this starts to happen the base system doesn't have much power it could be distorting . You could try sound insulation but if you like a good stereo in your car you should consider and upgrade like maybe the bimmertech helix 82 dsp or one of the solutions from this board. Base system in these is a POS even the next level up the Hi Fi is not very good for 50k car. |

With the windows up I have to turn it up pretty high. With the windows down it happens at extremely low volumes. I plan on amping this system and installing new underseat subs eventually, but I want to fix this door speaker problem first. I figured if it was distortion it would happen to all 4 speakers, or at least the 2 front speakers. |

You could measure the speaker resistance at the Head Unit
connector. From after that is leaves the head Unit. In the base system the floor speakers are wired in parallel with the floors. If you could somehow drive the speakers from another source other than the head unit it might tell you something. |

Hi was this ever resolved? I have the same issue and I have upgraded all the speakers, added two amps and I had base audio prior. Specific to the engine being on and bass and volume turned up
