Installation

Self-tapping screw (ø4 ⋅16 mm)

Installation board, etc. (thickness : 15 mm or more)

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.

2CAUTION

•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.
