Kicker ZX450.2 Manual Do Utilizador

Mounting: Choose a structurally sound location to mount your KICKER amplifi er. 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 amplifi er. If possible, mount the amplifi er in the climate-controlled passenger compartment. Drill 
four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifi er.

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 ZX 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 ZX 
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.
