The DX 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. A high-level signal can be run from the source unit’s speaker outputs to the
stereo RCA input on the end panel of the amplifi er using the KICKER ZISL as shown (make sure you set the DX
amplifi er’s input level switch to “HI”). Alternatively, the signal can be delivered to the amplifi er using the low-level
RCA outputs on the source unit. Set the input level switch on the end panel of the amplifi er to “LO”. 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.
