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.
