CONNECTIONS
K Before making connections
» Before installing the amplifier, be sure to disconnect the wire from the battery's negative
(-) terminal to prevent hazards caused by short-circuiting,
« When the amplifier installation and wiring have been completed, first check that they are
correct, then set the volume control to the minimum position to prevent speaker damage
due to high volume when power is supplied. After this, re-connect the battery's negative
[ - ) terminal which was disconnected previously,
M Caution on fuse
When the fuse is blown, first check that the cables are not short-circuited, then replace it
with a 15 Ax4 (60 A) fuse. (Use a 30 Ax4 fuse when measuring the maximum power
output.)
M Caution on speakers
This unit is an amplifier featuring a large power output of 420 W -t- 420 W (840 W in the
case of a bridged output) (when speakers with an impedance of 4 ohms are used).
Therefore, the speakers to be used should have a high maximum input capacity. If you have
to use speakers with a small maximum input rating, regulate the volume with careful con­
sideration to prevent speaker damage. The speakers must have an impedance of more than
4 ohms.
Ü Caution on RCA pin-plug cords
• When an audio system from manufacturers other than KENWOOD is connected to the
RCA pin jacks of this unit, adjust the input sensitivity adjustment potentiometer of this unit
according to the output level of the system.
• Because the RCA pin-plug cord is more sensitive to external noise than the DIN cable,
use consideration when placing the cord.
