AMPLIFIER TURNS DOWN
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.
