Kicker IX500.4 Owner's Manual page 3

Wiring: Disconnect the vehicle's battery to avoid an electrical short. Then, connect the ground wire to the
amplifi er. Make the ground wire short, 24" (60cm) or less, and connect it to a paint-and-corrosion-free, solid,
metal area of the vehicle's chassis. Adding an additional ground wire of this same gauge (or larger) between the
battery's negative post and the vehicle chassis is recommended.
The IX amplifi er has dual input sensitivity differential RCA inputs which will receive either high or low level signals
from your car stereo's source unit. Ideally, when connecting the source unit to the amplifi er, the IX amplifi er's input
level switch should be set to "LO" and a low-level signal should run from the source unit's stereo RCA output to
the stereo RCA input on the end panel of the amplifi er using RCA interconnect cable. If a low-level stereo RCA
output is not available on the source unit, the signal can be delivered to the amplifi er using the high-level speaker
outputs on the source unit. Set the input level switch on the end panel of the amplifi er to "HI". Crimp and solder
RCA connectors to the end of the speaker wire running from the high-level speaker outputs on the source unit
and connect the wire to the RCA Inputs on the end panel of the amplifi er or simplify the installation by using a
KICKER ZISL as shown below. Either input method will provide a low-level output signal at the RCA output, which
effectively passes the audio signal to another amplifi er or component. Keep the audio signal cable away from
factory wiring harnesses and other power wiring. If you need to cross this wiring, cross it at a 90 degree angle.

Install a fuse within 18" (45cm) of the battery and in-line with the power cable connected to your amplifi er. Install
a second fuse within 18" (45cm) of the amplifi er. If you ever need to remove the amplifi er from the vehicle after it
has been installed, the ground wire should be the last wire disconnected from the amplifi er--just the opposite as
when you installed it.
