! 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.
! Install and route the separately sold battery
wire as far as possible from the speaker wires.
Install and route the separately sold battery
wire, ground wire, speaker wires and the am-
plifier as far away as possible from the anten-
na, antenna cable and tuner.

About bridged mode

Speaker impedance is max. 4 W, please carefully
check. Improper connection to the amplifier may
result in malfunction or personal injury due to
burns from overheating.
For bridged mode for a two-channel amplifier,
with a 4 W load, either wire two 8 W speakers in
parallel, Left + and Right * (Diagram A) or use a
single 4 W speaker. For other amplifiers, please
follow the speaker output connection diagram for
bridging shown on rear: two 8 W speakers in par-
allel for a 4 W load or a single 4 W speaker per
channel.
For any further enquiries, contact your local
authorized Pioneer dealer or customer service.
