I just bought the car very recently i haven't been driving it much since it needs repairs but when i was listening to music from my aux in a 2010 c300 only the left side of the car had any sound except the small speaker on the pillar next to the windshield i'm really lost i tried searching it up haven't found much help so if you guys can please help me in any way you can because it is quite annoying

 

it's almost as if it's running in mono. so check the basics...balance and fader settings, make sure they are to your liking. also any EQ setting or presets. Make sure it's not in a 'mono' configuration. Hope this helps.

 

Okay I see well once I can I’ll see if it’s on the mono configuration but I know that all the eq settings are fine I checked that
