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
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 tur n 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.
