Question about Alpine MRP-M850 Car Audio Amplifier
My Alpine 850 wont turn on.. I set up just a cheap little amp that pushes 130watts rms to my high range front speakers. Unfortunately i played them a little loud and the speakers blew also cause they were old. But my problem is i had 2 amps in 4 gauge wire to 2 8 guages then it was after the speakers blew the subs the amp stayed on for a bit but then the amp shut off and i thought it would come back on but it didn't i checked all the fuses and they were good i'm really hoping its not deffective cause i dont wanna buy a new one -.-'
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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 is below ~11 volts, you need to check the wiring feeding whichever line is too low.
