TROUBLE SHOOTING
NO SOUND ON BANDPASS CHANNELS
Be sure that crossover points are set properly. Is the highpass set at a higher frequency than the lowpass or the lowpass set lower than the highpass, creating a no pass?

NO SOUND IN BRIDGED MODE
Check speaker wiring for short circuits or loose connections. Be sure that powerlock plugs are in place properly (screws facing up) and observe correct wiring diagram.
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.
