One speaker out

Hi guys,


I recently came back from a long trip abroad and my car wasn't turning on so I had to jump start it. When I drove the car after I realized just the front passenger speaker is no longer making any noise. I have a dynavin heady but installed along with aftermarket speakers. Anyone have an idea what the source of this issue could be? Thanks in advance

Try this BMW approved procedure:
Disconnect the ground cable at the battery
Disconnect the positive cable at the battery
Short the two cables together for a minimum of 10 minutes
Connect the positive cable to the battery
Connect the ground cable to the battery.

If you honestly thought I would just try this without further questioning, then you are clearly confused. I might be a novice when it comes to car audio, but I am not a moron. I do not see what you would get out of saying this to someone. One day you will do something like this and the person will go and try it and overheat their battery and electrocute themselves. Yea, it would be their fault for being stupid and just trying it, but you would be the cause of that situation. Great contribution you would be making to society, right? Grow up you dumb fvck.


Anyways, sorry for the rant. Does anyone have some real input on how I could figure out whether my amp is at fault or the speaker itself. Was looking to buy a new speaker set anyway if thats the case.

Uh, he's being serious. You don't short the battery out, you short the car out. It will drain any capacitors in electronic modules on the car forcing a complete system reset. It's actually a good idea. If it happened after having to jump start, it's distinctly possible that something just didn't completely reset right and is in a bad state due to power rail droop.

Only other thing I can suggest, would be to pull your door off, and test the speaker individually with a sound source. It doesn't sound like an issue with the speaker, though, since normally you'd at least get SOME sound even if it had gone bad. If the rest mentioned above doesn't help, you'll likely have to pull the unit out, and try to trace the lines back through the system and see if you can isolate where it went. If it's in the Dyavin, or the factory amp, or whatever.

It's a BMW-approved process. I've used numerous times on my bimmer and my friends' bimmers. The process does NOT short the battery but resets the electronix.

You might want to re-read the instructions. You're supposed to short the wires after the battery is disconnected.. I don't see how you can overheat a battery that isn't connected to anything.
