Fuse Requirements
You will need to install an in-line fuse or circuit breaker in the power wire within 18” of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your fuse or circuit breaker. You may also want to add a power distribution block near your amplifiers to distribute large gauge power cable to multiple amplifiers.

The LEDs provide the following indications:
1.Power - This LED illuminates RED when the amplifier power is turned on with the remote input (output muted). After a short time delay this LED will turn GREEN (amplifier ready).
2.Clip Output - This LED illuminates RED on the peaks of the output signal when the peaks are too high. This clipping causes audible distortion in the speakers.
3.Short - This LED illuminates RED on a short condition. The amplifier will turn off and try to turn back on.
4.Thermal - This LED illuminates RED on a thermal condition. The amplifier will turn off and turn back on in a minute or so.
Note: Read the AP-IV Protection Circuit section for additional information regarding Short and Thermal protection.
