A bit of a strange one this. I have the sph da120. It has been installed for approx 18mnths. I lost all sound today and it only comes back if I turn hard right
Anyone else heard of this issue? I checked all the connections and were all good. The only thing I can think of is a dry joint on one of the boards.
Cheers Chris

 

Check your wiring from HU to speakers. Ideally run a separate wire between the 2.

 

Thanks buddy. I did checks yesterday. I think it's internal as started working this morning until it heated up then no sound again.
