I am having a problem with my amp i plug in my sub woofer and it shuts off a red light turns on saying diagnoses what do i do i also am having problems with my alpine stereo i cant watch dvds because of the saftey switches i just bought the car and it was turned on with a button and the lights but i could not figure it out so i un pluged it and dont know what to do
One of your subs are blown if you un plug the subs from amp and the light turns on then its not the amp so try one sub at a time and see what one turns the red light on........its your subs or sub

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
