Before connecting the

amplifier

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 wire the speaker negative cable directly-

to ground.

! Never band together multiple speaker’snega-

tive cables.

! 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.
