Hey, as already about 2 weeks ago I shilided the problem with the sub. ->ICh turn on the car , then a pop from the sub and then there is nothing…so after 5 minutes the power amplifier turns off (Protect Led is on) and if I make the Rasio then on and off again everything is fine again ( sub is then also on ) So…. From Friday to today it was weirdly everything went great… car on sub as it should be…. This morning everything is also great…then I do he start the car again at noon, and swups there is the problem again AHHHHHHHH What the hell is going on… I really need your help… Thanks Oh another thing…. Can it be related to that my sub 4 Ohm has and the carpower end stage is up to 2 Ohm stabiel???
