FUSE
4
The amplifier inherently has no internal device fuse. Use the supplied fuse (50 A) with the fuse holder
and install it in the power cable between the 12 Volt pole of the vehicle battery and next to the +12V
terminal of the amplifier. The distance between the fuse and the amplifier should not exceed 30 cm.
ADDITIONAL CABLE FUSE (NOT INCLUDED)
5
Install an extra fuse (not included) for the +12V power cable near the battery to secure the power
cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be
adapted to the cable cross-section of the installed power cable (see table below).
IMPORTANT: The fuse on the battery does not protect the amplifier, but the cable between the battery
and the amplifier against short circuits.
