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. 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.
