206 rear speakers

First of all, hello friends, I have a 2004 model 1.4hdi x-line sw 206 vehicle, there are speakers at 4 doors but the front sounds very nice, there is no sound from the left in the back door, there is very little sound from the right, is it heard when I give it to the back but do you think the speakers are broken or is it a connection related event? they must have original speakers

It may be in the outbreak, or in the settings of the tape. I suggest you check the Balance and Fader settings.

they're okay bro no problem with them

Then it breaks up, my teacher has the same problem with me. There is no sound on the right door. The others are sizzling.

ok brother thanks i will remove the door covering
