Loss of treble??

Ok guys as I am driving I suddenly lost my treble or maybe my speakers but the bass is still there? It not only does it with the radio but CD and phone as well? It is intermittent. I am thinking maybe the amp is going but not sure what do you guys think? It is all stock EPS.

I'd listen to each speaker to see if there's any treble. If none have any, it'd be very strange if your blew all 7 tweeters. Could be the amp or headunit. Time for dealer.

Sounds like a head unit issue to me. That happens sometimes with radio, due to reception, but if it's happening with a CD, USB, etc., it has to be the head unit. Amplifier, as its name implies, only amplifies the signals. Finally, remember EPS has a separate equalizer; did you check it? Could have been reset by a gremlin . Good luck.
