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.(Use a power wiring cord with a diameter of 8 mm² (AWG 8) or greater.) For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit’s fuse capacity.The protective fuse should be the same capacity as the unit’s fuse capacity or somewhat larger. Be sure to install a protective fuse in the power cord near the battery.Do not turn the power on if the ground wire is not connected. 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 allow the wire to directly contact the edge of the iron plate by using Grommets.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.If it’s connected to the vehicle’s wiring harness, it can cause blown fuses etc.

Take the battery wire for this unit directly from the battery.If the unit does not seem to be working right, consult your Kenwood dealer.If you experience problems during installation, consult your Kenwood dealer.To prevent a short circuit when replacing a fuse, first disconnect the wiring harness.Using a fuse with the wrong rating may cause your unit to malfunction. When replacing a fuse, only use a new one with the prescribed rating.Also avoid places with too much dust or the possibility of water splashing. Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity.Do not open the bottom covers of the unit.Be sure the unit is connected to a 12V DC power supply with a negative ground connection.To prevent damage to the machine, take the following precautions:
