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.
• 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.
• 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.

Before you start

• 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.

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

The Protection function will operate in the conditions outlined below. If the Protection function is turned on, the power indicator will turn off, and the amplifier will shut down.

• If the speaker output terminal and speaker wire is short-circuited.
• If the temperature inside the amplifier gets too high.
• If a DC voltage is applied to the speaker output terminal.

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 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 500 mV), set to the NORMAL position. For use with an RCA equipped Pioneer car stereo, with max. output of 4 V or more, adjust level to match that of the car stereo output.
• If you hear too much noise when using the speaker input terminals, turn the gain control to higher level.

③ 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.
• 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.

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 ground speaker wire directly or band together multiple speakers' negative ( ) lead wires.
• 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.

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 shuts down until it has cooled to a certain designated temperature.

• Avoid routing wires through hot areas, such as near the heater outlet. Heat may damage the insulation, resulting in a short-circuit through the vehicle body.

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

• Firstly make temporary connections and check to ensure the amplifier and system operate properly.
• After installing the amplifier, confirm that the spare tire, jack and tools can be easily removed.

Example of installation on the floor mat or chassis

1 Place the amplifier in the desired installation location.

Insert the supplied tapping screws (4 mm × 18 mm) into the screw holes and push on the screws with a screwdriver so they make an imprint where the installation holes are to be located.

2 Drill 2.5 mm diameter holes at the imprints either on the carpet or directly on the chassis.

3 Install the amplifier with the use of supplied tapping screws (4 mm × 18 mm).
