! If the system remote control wire of the ampli-

fier is connected to the power terminal via the

ignition switch (12V 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

! Do not install or use this amplifier by wiring

speakers rated at 4 W (or lower) in parallel to

achieve a 2 W (or lower) bridged mode (Dia-

gram B).

Amplifier damage, smoke, and overheating

could result from improper bridging. The am-

plifier surface could also become hot to the

touch and minor burns could result.

To properly install or use a bridged mode and

achieve a 4 W load, wire two 8 W speakers in

parallel with Left + and Right * (Diagram A)

or use a single 4W speaker.

In addition, refer to the speaker instruction

manual for information on the correct connec-

tion procedure.

! For any further enquiries, contact your local

authorized Pioneer dealer or customer

service.
