About Bridged Mode; About Suitable Specification Of Speaker - Pioneer GM-D8604 Owner's Manual

Connecting the units
! 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's nega-
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

! Do not install or use this amplifier by wiring
speakers rated at 2 W (or lower) in parallel to
achieve a 1 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 2 W load, wire two 4 W speakers in
parallel with Left + and Right * (Diagram A)
or use a single 2 W 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.
