Kicker KEY200.4 Manuel D'utilisation page 7

Cut the looped red power cable located in the KEY
carton and install using the 20A fuse. The fuse should
be within 18" (45cm) of the battery and in-line with
the harness' power cable, which is connected to
your amplifier. If you ever need to remove the amplifier
from the vehicle after it has been installed, the ground
wire should be the last wire disconnected from the
amplifier--just the opposite as when you installed
it. The KEY amplifier is capable of using the wiring
directly from your head unit, but for best results it is
recommended you use power and ground wiring
from the vehicle's battery and chassis. KICKER
recommends 14 gauge wire.
If needed, cut off the RCA connections to use hi-level
input.
