Speaker sounds horrible - does warranty cover it?

Okay, I see a lot of people complaining about the JBL audio system and I will start off saying this is not that type of question. I will say it is not really a great system, but up until recently it did not drive me crazy. Starting about a week ago the front passenger side door speaker sounds like it is blown or something. There is a crackle during any type of bass at all.

I know people will say I probably blew it out or something jamming too loud, but honestly I don't listen to music that loud or really at all. Most of the time I listen to books and I am not 18 year old. Not knocking anyone who likes loud music - it is just not me. I only care that I dont hear a horrible crackling blown speaker sound.

Is there a check or anything I can do? If it is blown or something is off is it covered under warranty? It is an '08 and under the mileage, so I have the warranty. I don't see how I could have done anything out of the ordinary to cause this, but anything is possible.

Any advice appreciated.

 

thanks, i will go by the dealer and have them look at it. i mean one good thing is there is no, "well it sounds fine to me..." that can be played. the thing crackles like a bowl of cereal no matter what input comes in. i just really didnt feel like paying an arse-ton of money for a speaker on a car that is 6 months old and i did nothing to abuse it - as jpadc put it. it is only the one speaker.
