Question about Nitro BMW-482 Car Audio Amplifier
I Have a Bmw Nitro 1200 wat amp with 2 plye 1200watt dual voice coil spearker's and i have everything hooked up right, but when i turn my radio up, My amp turn's on to protection mode. and i dont even have the amp tuned that loud just dosent make any sense any help?
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.
