In 2010 to 2011.5 there was no Hi Fi in the United States. Normaly World Wide the Base system is standard.
If you bought this thing used the last guy could have messed with the system .
We saw one system come through here where the speakers were absent.

Turn the bass all the way down and move the fader to the speaker you want to check would be what you could do
without taking anything apart while turning the treble all the way up for the doors .
