Using a fuse with the wrong rating may cause your unit to malfunction. • To prevent a short circuit when replacing a fuse, first disconnect the wiring harness. NOTE • If you experience problems during installation, consult your Kenwood dealer. • Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit’s fuse capacity or somewhat larger. • For the power cord and ground, use a vehicle type (fireproof ) power wring cord. (Use a power wiring cord with the range of 5 mm2 (AWG 10) or more. ) • 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. 7 扬声器选择 • 使用输入额定值比放大器输出功率小的扬声器将会导致冒烟 或设备故障。 • 所连接的扬声器的阻抗必须为 2 欧姆或更高（立体声连接 时）；或者 4 欧姆或更高（桥接连接）。 当使用一组扬声 器时，必须在计算扬声器的 总阻抗之后，再连接合适的扬 声器。 ＜例＞ LIMITATIONS To the extent permitted by law, JVC KENWOOD makes no express warranties or representations other than set out in this warranty.
