i just noticed its not working.. the car is only 2 years old and has 37,000 miles on it... has this happened to anyone else? should i buy new speakers or do u think its just a loose wire?

 

The door panel is pretty easy to take off and check, theres a how to somewhere.

It may have gotten wet, the inside of the doors collect alot of water, I lost one on the passenger side due to water damage

 

my gf's drivers side speaker went out a week ago i checked the wiring and everything then i even took out the speaker and tested it on a radio and it didn't work so i just replaced the 2 front speakers yesterday my guess is it was blown....

door panel isn't hard to take off either

 

Lots of water in the door, I have to pull my passenger speaker this weekend and solder and hot glue the connection (after cleaning the rust off it) so it works again and hopefully won't stop working. (I have aftermarket speakers, but am sure the stocks can have the same issue with water.
