FUSE RECOMMENDATIONS
D7 Professional Reference Series Amplifiers
, by design, require external fusing.
Research has shown that a circuit board mounted fuse can create a drop in
available DC voltage at the input of the power supply resulting in increased
current draw.
We recommend that you install the correct size fuse/holder combination to the
main power cable within 18 inches of the battery. This will protect your vehicle
from fire damage due to a short circuit to the chassis or vehicle body. If a single
amplifier is installed, follow the fuse recommendation below. If installing
multiple amplifiers, add up the total fuse ratings of all installed amplifiers. This
should be used as your main fuse rating.
