03 Connecting the units

!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.

About suitable specification of speaker

Ensure speakers conform to the following standards, otherwise there is a risk of fire, smoke or damage. Speaker impedance is 2 W to 8 W, or 4 W to 8 W for two-channel and other bridge connections.
