Thanks guys !
I read some threads about sound system but every thread gives some differents opinions. Once the head unit once the speakers !
I'd go with speakers changing option but it's way complicated to change the doors ones !
Anyway the sound is so awful in mine that I doubt something is not wrong... The doors speakers dont give anything than muffled bass sounds. My head unit setting is min bass max treble ans it's still too much bassy...
Is that normal or...
Thanks !
