With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF. 6 English n Power wire connection GND LINE IN 1.0 INPUT SENSITIVITY(V) BASS ENPHASIS POWER IN GND FUSE(25A) FREQUENCY(Hz) L R SPEAKER LEVEL INPUT 25 Terminal cover Battery Ground cable (Commercially available part) Battery cable (Commercially available part) Power control cable (Commercially available part) Round terminal (Large) Power terminal Protective Fuse Round terminal (Small) Round terminal (Medium) 2WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal. 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). • When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. Power terminal Connect to their respective terminals the power control wire, power supply wire, and ground wire, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section.
