Installation . . . as easy as 1, 2, 3

1.Mounting Choose a structurally sound location to mount your Kicker amplifier. The controls on the top of the amplifier need to be accessible for adjustment. Make sure there are no items behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm) of open ventilation for the amplifier. If possible, mount the amplifier in the climate-controlled passenger compartment. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifier.

2.Wiring Disconnect the vehicle’s battery to avoid an electrical short. Then connect the ground wire to the amplifier. 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 between the battery's negative post and the vehicle chassis of this same gauge (or larger) is recommended.

Use a twisted pair of RCA (low-level) interconnect cable to feed the audio signal to the amplifier.

Two Channel Operation (Stereo) These ZX amplifiers are capable of operating into a minimum impedance of 2 ohms per channel in stereo operation. See Figure 2.

Bridged Operation (Mono) ZX.2 series amplifiers are capable of operating into a minimum impedance of 4 ohms when in bridged operation. See Figure 3.
