I tried a search, didn't come up with anything...Anyone know or tried to have the speakers replaced under warranty?

Not speakers, but two front grills that were vibrating badly!

you can get themreplaced if there is something wrong

Even if I caused it, like say too much bass way too loud?

Shouldn't a radio be matched with speakers to handle the output? Sounds like a defect that should be replaced if your stock speakers can't handle the output of your stock radio.

I would try anyway. I think you have a good case. Not normal wear and tear in my opinion.

Worst case scenario = they say they won't cover them. It's worth asking. Don't be saying you blew them out messing around, tho... Everything sounded fine then suddenly the sound changed!
