To prevent damage to the machine, take the following precautions: Be sure the unit is connected to a 12V DC power supply with a negative ground connection. [. . . ] Do not allow the wire 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. Be sure to install a protective fuse in the power cord near the battery. 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. ) · 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. If you experience problems during installation, consult your Kenwood dealer. If the unit does not seem to be working right, consult your Kenwood dealer.

After installation, check that the brake lamps, winkers, and wipers work properly. Gray/Black Genuine-accessory car stereo (No line output center unit etc. Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. [. . . ] As this unit accepts speakers with a minimum impedance of 1 ohm, connect speakers with 1-ohm or higher impedance to these terminals. The rated input of the speakers should be no less than the maximum output of the amplifier. Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuineaccessory car stereo. The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. [. . . ]
