Installation procedure

1. Remove the ignition key and disconnect the negative - terminal of the battery to prevent short

circuits.

2. Set the unit according to the intended usage.
3. Connect the input and output cables of the units.
4. Connect the speaker cables.
5. Connect the power cable, power control cable and grounding cable following this order.
6. Install the unit in the car.
7. Connect the negative - terminal of the battery.

• Be sure to turn the power off before changing the setting of any switch.
• If the fuse blows, check cables for shorts, then replace the fuse with one of the same rating.
• Check that no unconnected cables or connectors are touching the car body. Do not remove

caps from unconnected cables or connectors to prevent short circuits.

• Connect the speaker cables to appropriate speaker connectors separately. Sharing the negative

cable of the speaker or grounding speaker cables to the metal body of the car can cause this
unit to fail.

• After installation, check that the brake lamps, winkers, and wipers work properly.

2CAUTION

Installation

• Since the power amplifier has no parts which require operation, it can be installed at a position

away from the driver’s seat without any hindrances.
As generally accepted positions for its installation, places such as inside the trunk, etc. can be
considered.

• Use the extension cables. (Optional.)

• Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be

damaged.

• Install this unit in a location which allows heat to easily dissipate.

Once installed, do not place any object on top of the unit.

• The surface temperature of the amplifier will become hot during use. Install the amplifier in a

place where people, resins, and other substances that are sensitive to heat will not come into
contact with it.

• When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check

that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or
wiring harness, and be careful not to cause scratches or other damage.

• Do not install near the dashboard, rear tray, or air bag safety parts.
• The installation to the vehicle should securely fasten the unit to a place in which it will not

obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may
cause injury or an accident.

• After installing the unit, check to make sure that electrical equipment such as the brake lamps,

turn signal lamps and windshield wipers operate normally.
