Hi,
As of recent my rear door speakers are not working at all, I have 4 x Focal door speakers, 2 x Sound stream amps and 1 x Sound stream sub. Only has started happening since the car wouldnt start due to the clamps on battery leads werent secured properly and before I realised that was the issue I used a jump starter pack on the car and didnt turn over 3 times, even charged the battery but ended up getting the car started and now rear speakers not working, any help would be appreciated.
