Before connecting/ installing the amplifier

WARNING

• The use of a special red battery and ground wire RD-223, available separately, is recommended. Connect the battery wire directly to the car battery positive terminal and the ground wire to the car body.
• 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.
  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.

Before you start

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 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.

What's what

GM-A5602

GM-A3602

To adjust the switch, use a flathead screwdriver if needed.

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.

② FREQ (cut off frequency) control

Cut off frequency selectable from 40Hz to 500Hz if the LPF select switch is set to ON.

BASS BOOST (bass boost level control) switch

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

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

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

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

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

Before installing the amplifier

WARNING

• To ensure proper installation, use the supplied parts in the manner specified. If any parts other than those supplied are used, they may damage internal parts of the amplifier, or become loose causing the amplifier to shut down.
• Do not install in:

Places where it could injure the driver or passengers if the vehicle stops suddenly.
Places where it may interfere with the driver, such as on the floor in front of the driver's seat.

• Install tapping screws in such a way that the screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the car, which can result in fire.
• Make sure that wires do not get caught in the sliding mechanism of the seats or touch the legs of a person in the vehicle as short-circuit may result.
• When drilling to install the amplifier, always confirm no parts are behind the panel and protect all cables and important equipment (e.g. fuel/brake lines, wiring) from damage.

CAUTION

To ensure proper heat dissipation of the amplifier, ensure the following during installation:

• Allow adequate space above the amplifier for proper ventilation.

• Do not cover the amplifier with a floor mat or carpet.

• Protection function may activate to protect the amplifier against overheating due to installation in locations where sufficient heat cannot be dissipated, continuous use under high-volume conditions, etc. In such cases, the amplifier reduces the power output or shuts down until it has cooled to a certain designated temperature.

• Place all cables away from hot places, such as near the heater outlet.

• The optimal installation location differs depending on the car model. Secure the amplifier at a sufficiently rigid location.

• Check all connections and systems before final installation.
  After installing the amplifier, confirm that the spare tire, jack and tools can be easily removed.
