Tower Speaker Problem
 

So, yesterday one of my tower speakers starts making weird noises when the volume is up like there's electrical interference and with the volume down at low levels it sounds fine. Since this happened suddenly yesterday afternoon I think one of the tower speakers has a problem. In my words the speaker is blown. The speaker is in a Roswell light and speaker bar and the speakers are Kicker components on my 2009 22SSV. Would this be something covered under warranty by Supra? If not what kind of economical solutions or replacements would be available? I would like to replace all of them with Wetsounds but, that's not really in the budget right now.
