Hello.
I was wondering if anyone has a clue what could cause it, the rear door speakers play no sound. All other speakers work fine. The car does not have the original stereo anymore, it has been replaced with a new aftermarket console, because the original stereo was damaged ( sometimes didnt work at all and other times the speakers started making very weird noises when the ignition was turned on)
I am afraid to take it to the dealership because i think it will be very expensive, so i thought i will ask here first, maybe somebody has a clue.
Thanks.
