so im crusing back from my girlfriends house listening to music at a very normal level. I dont listen to rap music or blast music in anyway, just your typical normal listening. anyway suddenly this awful rattling sound starts coming from my passenger door. Immediately im like wtf? Upon closer hearing it sounds like the tweeter or mid ( im thinking its the mid) is bottoming out - but it shouldnt be doing that? Are they known for going out like that?
Most important question - Will the dealer cover this with no problems? Last thing i want them to do is say " well you listen to music loudly because you're in your 20's and thus you need to pay 1000 bucks to fix everything" or some other typical stealership excuse. TIA! |

If speakers never failed, parts wouldn't sell them.
If the speaker is bottoming out, it MIGHT be the amp at fault. Usually a dealer will replace one or two speakers before telling you you're abusing the equipment.

Stuff happens... I've seen the X5 amp fail from water collecting back there, ditto some E36, but hard to say. I don't even know which amp you have (fiber-optic or not).

I had heard of the evils of rap music, but never about how it forces you to rotate the volume knob... Rap and hip-hop music actually have severely boosted bass notes, and can damage audio systems when turned up due to the demands these notes make on the system's speakers and amplifier.

sorry i didnt mean anything derogatory about rap music - i mean that rap music has low bass notes and tends to hit harder than say alternative rock or classical music.
Sorry for any confusion! |

I used to think distortion blew speakers, too, but as it turns out I was corrected (in a pretty detailed manner) by a speaker engineer on another forum a year or two ago.
If the voice coil is receiving less power than it can handle, it doesn't care if it's distorted or not. There are some folks who hold that infrasonic content will heat up a voice coil and cause failure, and some who disagree. Apparently the rule of thumb is, most amps can deliver 2X the amount of distorted power as they can clean power. So driving an amp into distortion is also driving it over its rated output. So I was wrong. It's easier to blow a 100W speaker with an 80W amp, which can deliver 100W+ when driven into distortion, than it is a 100W speaker with a 50W amp, which can't exceed the power rating (and would sound far worse doing so anyway, so it would be unlikely). Of course, I've seen speakers blow on amps well below their rating. I now believe those amps had their power ratings assigned by the marketing department, were totally made-up lies, like many specs that come from manufacturers.
