Check Power and Remote turn-on wire
for voltage. Make sure Ground wire is
secure.
Both excessive temperature and low impedance (or short circuit)
conditions will activate the amplifier's AM IV protection circuitry, which
turns down the amplifier's output. When the amplifier cools down, or the
impedance is corrected, the AM IV will restore full power.
If your amp is turning down check your speakers and wiring for low
impedance and short circuits.Also,ensure that there is nothing blocking
the normal convective airflow of the amplifier. No obstruction should be
within 2" of the amplifier on all sides.
NOTE: Low battery voltage will cause the amplifier to run warmer.
