well a good friend of mine has an s4 it comes with a bose set up similar to ours he has had his car for 2 months and his rear speakers have blown (apparently this is a problem with many s4 owners according to audiworld)

what im asking is has anyone had any problems with their factory system ? i plan to add a system soon other than my head unit which will remain stock but it may take a little while ...

 

The only problem any of us have had is the factory system generally sucks! I don't think it has enough power to blow anything.
