Installation

1.Mounting Choose a structurally sound location to mount your Kicker ampliﬁer. 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 of this same gauge (or larger) between the battery's negative post and the vehicle chassis is recommended.

The ZX ampliﬁer has dual input sensitivity differential RCA inputs which will receive either high or low level signals from your car stereo’s source unit. Ideally, when connecting the source unit to the ampliﬁer, the ZX ampliﬁer’s input level switch should be set to “LO” and a low-level signal should run from the source unit’s stereo RCA output to the stereo RCA input on the end panel of the ampliﬁer using RCA

CONFIGURATION

interconnect cable. If a low-level stereo RCA output is not available on the source unit, the signal can be delivered to the ampliﬁer using the high-level speaker outputs on the source unit. Set the input level switch on the end panel of the ampliﬁer 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 ampliﬁer as shown in Figure 1. Either input method will provide a low-level output signal at the RCA output, which effectively passes the audio signal to another ampliﬁer or component. Keep the audio

at a 90 degree angle.

Install a fuse within 18” (45cm) of the battery and in-line with the 8 gauge power cable connected to your ampliﬁer. If you ever need to remove the ampliﬁer from the vehicle after it has been installed, the ground wire should be the last wire disconnected from the ampliﬁer--just the opposite as when you installed it. See the fuse chart on the following page for power and ground wire size, and fusing recommendations.
