^^^ Doesn't take much to kill stock speakers... Could've cranked it up too high & popped the cone... Or somehow there may have been a short in the system which has popped the front speakers.
Anything possible & I have to admit it's happened to me in other cars in the passed (Except with the rear speakers).
Aggree it could be a loose screw or something, but if the sound is actually coming from the speakers (As stated) then I doubt that would be the issue + what are the chances of the same thing happening on both sides of the car?
