Did you try adjusting the fade control? Possibly got changed inadvertently?

I had the same issue, I have the extended warranty and took it to the dealer, had them check and both speakers were going bad. They ordered two new ones and she sounds great now. If i could have swung it, I would have upgraded to a better type speaker, but am down on disability right now so moneys tight. Now would be a good time to check to see if your stereo bracket is rubbing through your fairing. Unless you have already had it off and checked.
Ya... Mine is still under warranty, but I was hoping it would be an easy fix. Planning to do a few mods over the winter, so ill be able to take a better look at it when I take the fairing off.
