Connecting the units 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 capacity of the wire is limited. About bridged mode 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 negative cables. ! If the system remote control wire of the amplifier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will remain 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 amplifier as far away as possible from the antenna, antenna cable and tuner. ! 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 (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier 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 4 W speaker. In addition, refer to the speaker instruction manual for information on the correct connection procedure. ! 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 for stereo connection, or 4 W to 8 W for monaural and other bridge connection. En
