As generally accepted positions for its installation, places such as inside the trunk, etc. 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. • Do not connect cables and leads to both RCA cable input jacks and the speaker input terminals simultaneously, for this may cause malfunction or damage. • Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF. 6 English s Power wire connection LINE IN L INPUT SENSITIVITY(V) 1. 0 0. 5 50 MIN 0. 3 MAX 30 90 120 BASS ENPHASIS OFF 1 70 SPEAKER LEVEL INPUT LEFT RIGHT POWER IN BATT ON GND P.

Wiring • If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire. • Do not allow the cord to directly contact the edge of the iron plate by using Grommets. • Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery‘s negative - terminal. Do not turn the power on if the ground wire is not connected. • Be sure to attach a protective fuse into the battery wire close to the battery. Use a protective fuse having a capacity that is about 10 A higher than the maximum current drawn by the amplifier. • Use vehicle-type (fire-resistant) power supply wiring wire for the battery wire and the ground wire. The current capacity of the power supply wiring wire should be about 10 A higher than that of the protective fuse capacity (which means about 20 A higher than the maximum current drawn by the amplifier). [. . . ] (No sound from one side. ) POSSIBLE CAUSE • Input (or output) cables are disconnected. • Protection circuit may be activated. • The fuse may be blown because the volume was too high. The input sensitivity adjusting control is not set to the correct position. [. . . ]
