Setting the Unit

What

’s what

Front side

Rear side

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

1 Power indicator

The power indicator lights up to indicate power ON.

2 GAIN (gain) control

Adjusting gain controls CHANNEL A (channel A) and

CHANNEL B (channel B) helps align the car stereo output to the Pioneer amplifier. Default setting is the

NORMAL position.

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.

! If using only one input plug, set the gain controls for speaker outputs A and B to the same position.

! 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.

3 LPF (low-pass filter)/HPF (high-pass filter) select switch

Switch the settings based on the connected speaker.

! When the Subwoofer is connected:

Select

LPF. This eliminates high range frequency and outputs low range frequency.

! When the full range speaker is connected:

Select HPF or OFF. HPF eliminates low range frequency and output high range frequency.

OFF outputs the entire frequency range.

4 INPUT SELECT (input select) switch

Select 2CH for two-channel input and 4CH for four

–channel input.

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.

Installation

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 are not caught in the sliding mechanism of the seats, resulting in a short-circuit.

! 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.

! 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 (1/8 inch) 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).

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.

! 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.
