WARNING
! Secure the wiring with cable clamps or adhe-
sive tape. To protect the wiring, wrap sections
in contact with metal parts in adhesive tape.
! Never cut the insulation of the power supply
to feed power to other equipment. Current ca-
pacity of the wire is limited.
CAUTION
! Never shorten any wires, the protection circuit
may malfunction.
! Never ground speaker wire directly or band to-
gether multiple speakers' negative (*) lead
wires.
! If the system remote control wire of the ampli-
fier is connected to the power terminal via the
ignition switch (12 V DC), the amplifier will re-
main on with the ignition whether the car
stereo is on or off, which may exhaust battery
if the engine is at rest or idling.
