Mounting Instructions When selecting a location to mount your Kicker amplifier be sure it is structurally sound and that there are no items behind the area that could be damaged by the screws. Check for wiring, brake lines, fuel lines, gas tanks, etc. All amplifiers generate heat under normal operation. Be sure to choose a location that allows adequate ventilation for the amplifier. Also consider that the air temperature inside an automobile’s trunk can reach upwards of 140 degrees fahrenheit.

Wiring Instructions Signal can be input into the amplifier using either the low level RCA input connections or the high level (speaker level) connections. Using the low level RCA connections is the preferred method. Use the high level inputs only if your head unit does not have low level RCA type outputs. WARNING-Use Only One...

System Diagrams The following diagrams show the most common configurations for your Kicker KX series amplifier. TWO CHANNEL OPERATION (STEREO) KX series amplifiers are capable of operating into a minimum impedance of 2 ohms per channel in stereo operation. LEFT SPEAKER(S) + _ SIGNAL IN + GROUND _ RIGHT SPEAKER(S) REMOTE TURN-ON 18" or less +12V BATTERY FUSE BRIDGED OPERATION (MONO) KX series amplifiers are capable of operating into a minimum impedance of 4 ohms when in bridged operation.

ADJUSTING AMPLIFIER CONTROLS Your Kicker amplifier has two rotary controls and one switch on the end panel. These controls ensure the reliability and performance of the amplifier, so they need to be set correctly. CROSSOVER SWITCH NEVER CH HANGE THE CR ROSSOVER SWITCH H SETTING WITH THE SYSTEM ON! The switch located on the end panel next to the RCA jacks is for setting the internal crossover. In the OFF position the amplifier passes a full range signal to the speakers.

TROUBLE SHOOTING If your amplifier does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There are two LEDs on the end panel of your Kicker KX series amplifier, one green and one red. When the green LED is lit this indicates the amplifier is turned on and no trouble exists.

ÖCheck gain setting, turn down if set too high. ass response:: Poor stereo imaage or reduced ba ÖCheck system phasing by turning the balance control from left to right. If there is more bass output when turned to either side then check your speaker wiring for proper positive and negative connections.
