Before you start	01

BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:

!Do not turn up the volume so high that you can’t hear what’s around you.

!Use caution or temporarily discontinue use in potentially hazardous situations.

!Do not use headphones while operating a motorized vehicle; the use of headphones

may create a traffic hazard and is illegal in many areas.

Before connecting/ installing the amplifier

WARNING

!Handling the cord on this product or cords associated with accessories sold with the product may expose you to chemicals listed on proposition 65 known to the State of California and other governmental entities to cause cancer and birth defect or other reproductive harm. Wash hands after handling.

!This unit is for vehicles with a 12 V battery and negative grounding. Before installing in recreational vehicles, trucks or buses, check the battery voltage.

!When installing this unit, make sure to connect the ground wire first. Ensure that the ground wire is properly connected to metal parts of the car’s body. The ground wire of the one of this unit must be connected to the car separately with different screws. If the screw for the ground wire loosens or falls out, it could result in fire, generation of smoke or malfunction.

!Be sure to install the fuse to the battery wire.

!Always use a fuse of the rating prescribed. The use of an improper fuse could result in overheating and smoke, damage to the product and injury, including burns.

!Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Determine and resolve the cause, then replace the fuse with and identical equivalent.

!Always install the amplifier on a flat surface. Do not install the amplifier on a surface that is not flat or on a surface with a protrusion.

Doing so could result in malfunction.

!When installing the amplifier, do not allow parts such as extra screws to get caught between the amplifier and the automobile. Doing so could cause malfunction.

!Do not allow this unit to come into contact with liquids. Electrical shock could result. Also, damage to this unit, smoke, and overheating could result from contact with liquids. The surfaces of the amplifier and any attached speakers may also heat up and cause minor burns.

!In the event of any abnormality, the power supply to the amplifier is cut off to prevent equipment malfunction. If this occurs, switch the system power off and check the power supply and speaker connections. If you are unable to determine the cause, please contact your dealer.

!Always disconnect the negative * terminal of the battery beforehand to avoid the risk of electric shock or short circuit during installation.

!Do not attempt to disassemble or modify this unit. Doing so may result in fire, electric shock or other malfunction.

CAUTION

!Always keep the volume low enough to hear outside sounds.

!Extended use of the car stereo while the engine is at rest or idling may exhaust the battery.

About the protection function

This product has protection function. When this product detects something abnormal, the following functions will operate to protect the product and speaker output.

!The POWER/PROTECT indicator will turn red and the amplifier will shut down in the situations outlined below.

Section

01Before you start

—If the temperature inside the amplifier gets too high.

—If a DC voltage is applied to the speaker output terminal.

!The POWER/PROTECT indicator will turn red and the output will be muted in the situations outlined below.

—If the speaker output terminal and speaker wire are short-circuited.

!Despite correct volume and gain settings, the unit sound still cuts out periodically. In such cases, please contact the nearest authorized Pioneer Service Station.

Gain control of this unit

Preout level: 2 V (Standard: 500 mV)

Preout level: 4 V

Above illustration shows NORMAL gain setting.

Relationship between amplifier gain and head unit output power

If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power.

Signal waveform when outputting at high volume using amplifier gain control

Signal waveform distorted with high output, if you raise the gain of the amplifier the power changes only slightly.

Before connecting the amplifier

WARNING

!Secure the wiring with cable clamps or adhesive 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.

Section

03 Connecting the units

CAUTION

!Never shorten any wires, the protection circuit may malfunction.

!Never wire the speaker negative cable directlyto 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 am-

plifier as far away as possible from the antenna, antenna cable and tuner.

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, or 4 W to 8 W for two-channel and other bridge connections.

Speaker channel	Power

Four-channel output

Nominal input:

Min. 100 W

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 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 2 W load, wire two 4 W speakers in

parallel with Left + and Right * (Diagram A) or use a single 2 W speaker.

Notes

!If speaker wires with an RCA pin cord from a headunit are connected to this amplifier, the amplifier will automatically turn on when the headunit is turned on. When the headunit is turned off, the amplifier turns off automatically. This function may not work with some headunits. In such cases, please use a system remote control wire (sold separately). If multiple amplifiers are to be connected together synchronously, connect the head unit and all amplifiers via the system remote control wire.

!Connect the system remote control wire when you wish to only turn on the car stereo, not the amplifier.

Connecting the units	03

!This amplifier automatically selects an input

signal mode between the RCA level and the speaker level by detecting an input signal.

Solderless terminal connections

!Since the wire will become loose over time, it must be periodically inspected and tightened as necessary.

!Do not solder or bind the ends of the twisted wires.

!Fasten while making sure to not to clamp the insulating sheath of the wire.

!Use the supplied hexagonal wrench to tighten and loosen the terminal screw of the amplifier and use it to securely fasten the wire. Be careful to avoid excessive tightening of this screw, which may damage the wire.

1 Route battery wire from engine compartment to the vehicle interior.

!When drilling a cable pass-hole into the vehicle body and routing a battery wire thorough it, take care not to short-circuit the wire damaging it by the cut edges or burrs

of the hole.

After completing all other amplifier connections, finally connect the battery wire terminal of the amplifier to the positive (+) battery terminal.

WARNING

If the battery wire is not securely fixed to the terminal using the terminal screws, there is a risk of overheating, malfunction and injury, including minor burns.

!Always use the recommended battery and ground wire, which is sold separately. Connect the battery wire directly to the car battery positive (+) terminal and the ground wire to the car body.

!Recommended wires size (AWG: American Wire Gauge) is as follows. The battery wire, the ground wire and the optional direct ground wire must be same size.
