Should this occur, the PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the protection circuitry to become activated. If the amp shut off because of a thermal overload, allow it to cool down before attempting to restart. If the shutdown occured because of an input overload, or speaker short circuit, be sure to correct these conditions before attempting to restart the amp. To reset the amp, turn the REMOTE power off and on again. 13 Remote

Follow these steps: 1. Set the volume control on your head unit to about the 2/3 position. 2. Adjust the amplifier LEVEL control(s) to an average listening position. LLRR 3. Turn the head unit volume all the way down, and listen for background noise. orange black black 4. Start your vehicle, and again, listen for background noise. 5. By fine tuning the LEVEL control(s), you can reduce background and engine noise, if present. orange These adjustments should only be made once. After that, use the
Try to drive as high a signal level from the head unit as possible. Protection LED comes on when the amplifier ispowered up. • Check for shorts on speaker leads. • Check that the volume control on the head unit is turned down low. • Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty. Amplifier(s) gets very hot. • Check that the minimum speaker impedance for that model is correct. • Check for speaker shorts. • Check that there is good
