are my speakers blown? (2013 gls canada)

Hey guys, I have about 24,000 km on my 2013 Hyundai Elantra. Over the past weeks I swear my audio quality has been more 'tingie' and less clear. Other then using the dash to listen to specific speakers....what options do I have from Hyundai to repair these? My dealership hasn't been great about prior issues...


Thanks
