01 Before you start

!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 follow-

ing functions will operate to protect the product and speaker output.

!The power indicator will turn off and the amplifier will shut down in the situations outlined below.

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

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

!The amplifier will reduce the power output if the temperature inside the amplifier gets high. If the temperature gets too high, the power indicator will turn off, and the amplifier will shut down.

Important (Serial number)

The serial number is located on the bottom of this unit. For your own security and convenience, be sure to record this number on the enclosed warranty card.

Note

Before installing this unit in your vehicle, refer to the illustration below and remove the tag (GMA5602 only).

Do not use the parts you have removed (screws etc.) when installing the unit in your vehicle.

1 LPF (low-pass filter) switch

Switch the settings based on the connected speaker.

!When the Subwoofer is connected: Select ON. This eliminates high range frequency and outputs low range frequency.

!When the full range speaker is connected:

Select OFF. OFF outputs the entire frequency range.

3BASS BOOST (bass boost level control) switch

You can select a bass boost level from 0 dB, 6 dB and 12 dB.

4GAIN (gain) control

If output remains low, even when the car stereo volume is turned up, turn controls to lower level. If distortion occurs when the car stereo volume is turned up, turn these controls to higher level.

!For use with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. For use with an RCA equipped Pioneer car stereo, with maximum output of 4 V or more, adjust level to match that of the car stereo output.

!For use with an RCA equipped car stereo with output of 4 V, set to the HIGH position.

!If you hear too much noise when using the speaker input terminals, turn the gain control to higher level.

5 Power indicator

The power indicator lights up to indicate power ON.

Setting gain properly

!Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection.

!When outputting high volume sound etc., this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down.

Section

02 Setting the unit

!A cut in sound output may indicate improper setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output.

!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

If the signal waveform is distorted due to high output, even if the amplifier gain is raised, the output power will change only slightly.

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.

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.

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.

03 Connecting the units

!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.

About bridged mode

!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 (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 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.

Connecting the power terminal

The use of a special red battery and ground wire RD-223 (sold separately) is recommended. Connect the battery wire directly to the car battery positive terminal + and the ground wire to the car body.

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.

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 thor-

ough 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.
