my back speakers all of a sudden dont work anymore... do you know what it could be?

i was playing music at 19
I left to work and came back and now they dont work..
i dont think i blew them up cause they would at least play music right?

 

It would lead me to suspect the connection either at the headunit or the amp has been disconnected. If you don't know what to do, take it back to the dealer.

 

check the fader

 

take it to the dealer

 

the fader is not an issue.
The car is an 03 and no longer has warranty..
Do you think its time for an upgrade?

 

i would hook up a volt meter on the rear speaker wire to see if you're
getting any signal.

 

k so i looked again and the back speakers seem to be on, but they are much lower now, does that mean theyre blown?

I thought that when they blown, they sounded distorted..
