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.

AMPLIFIER STATUS LEDS
1 2
The LEDs provide the following indications:
1.Power - These LEDs illuminates the center Precision Power logo background when the amplifier power is turned on.
2.Short - These LEDs behind the PPI logo will flash to indicate a short on the output.
2.Thermal - These LEDs behind the PPI logo will extinguish if the amplifier is in thermal shutdown protection.
Note: Read the AP-IV Protection Circuit section for additional information regarding Short and Thermal protection.
