Should the amplifier go into proteciont mode, simply

disconnect all RCA and speaker leads, while

keeping +12 volt, power ground and remote leads

connected. Now turn the amplifier back on, and if

the PROTECT-LED lights, the amplifier has an

internal fault. If not, plug the RCA cables back, and

reset the amplifier. If it goes into protection mode

now, the fault lies in the input, either with bad cables

or source unit. If the amplifier seems fine with RCA

cables plugged in, connect the speakers, one at a

time, and if one of the speakers or its wiring is faulty,

it will activate the diagnostic system.
