Installation

Wiring

Signal is input into the amplifier using the low level RCA input connections. If your source unit does not have RCA output connectors you will need to use a Hi-Lo level signal adapter. See your Kicker dealer for more details on this.

The output (PAST) RCA jacks provide an unaltered signal output to feed another amplifier or component.

SOURCE UNIT

The ground should be connected to the amplifier first before making any of the other connections. This wire should be as short as possible (24 inches or less) and connected to a paint/corrosion free solid metal area of the car’s chassis. Use the same gauge wire as recommended for the amplifier’s power connection to the battery. Adding an additional ground wire between the car battery’s negative post and the car chas- sis of this same gauge (or larger) is also recommended.

If you ever need to remove the amp from the vehicle after it has been installed, the ground wire should be the last wire disconnected from the amplifier, just the opposite of when you installed it.

A fuse must be installed within 18 inches of the battery to protect the power wire feeding your amplifier. This fuse should be of at least the same value used in the amplifier but no higher than the capacity of the power wire. See the charts below for wire size and fusing recommendations.

MULTIPLE SPEAKERS OR VOICE COILS PARALLEL WIRED

 

 

SX.1 series amplifiers are capable of powering multiple speakers or voice coils wired in parallel as long as the minimum impedance does not drop below 2 ohms (SX650.1) or 1 ohm (SX1250.1).

The use of twisted pair interconnects is recommended for all installations to minimize noise. When routing these cables through the automobile, try to keep them away from factory wiring harnesses and other power wiring. If you need to cross any of this wiring do so at a 90 degree angle to reduce the possibility for noise problems.

When working with power connections it is always recom- mended that you disconnect the battery to prevent accidents.
