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. 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.
