Introduction KX.2 Series Amplifier Owner’s Manual KX150.2 / KX200.2 / KX250.2 Two Channel Models: 2 Attention: Congratulations! Please record your purchase information in the area below. We recommend attaching the original sales receipt to this manual for future reference. If you require service on this speaker during the warranty period, you will need to provide this information and a copy of the original sales receipt to Kicker for validation of warranty repairs.
Low Impedance Operation Class A/B stable into 2 ohm stereo or 4 ohm mono loads. EndKaps Cast aluminum, custom, removable covers to protect and hide all your wiring connections to the amplifier. Can be prepped and painted any custom color you choose. SORT Protection Circuitry (Short circuit, Over-voltage, Reverse polarity, Thermal) Protects amplifier from accidents and undesirable operation. Two Year Warranty When purchased from an Authorized KICKER dealer.
Installation Mounting When selecting a location to mount your Kicker amplifier be sure it is structurally sound and that there are no items behind the area where the screws will be driven that could be damaged. Check for wire harnesses, 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.
Signal can be input into the amplifier using either the low level RCA input connections or the high level (speaker level) input connections. Using the low level RCA connections is the preferred method. Use the high level inputs only if your source unit does not have low level RCA type outputs. Connecting to the amp with either input connection will provide a low level signal at the output (PAST) RCA jacks.
Installation System Diagrams The following diagrams show the most common configurations for your Kicker KX series amplifier. TWO CHANNEL OPERATION (STEREO) These KX amplifiers are capable of operating into a minimum impedance of 2 ohms per channel in stereo operation. Modern high performance speakers have a lower DC Resistance than what used to be available.
USING THE SIGNAL OUTPUT JACKS (PAST) The Output (Pre Amp Signal Transfer) RCA jacks allow you to send the incoming signal from one Kicker KX series amplifier to another amplifier or processor without the need for Y cables. The signal from the PAST jacks is identical to the signal fed to the amplifier via its RCA input jacks or the High Level inputs and is not affected by the amplifier’s built in crossover. Installation System Diagrams WARNING - Use either the Hi-Level or RCA Inputs.
Navigation Operation On your Kicker amplifier there are three rotary controls on top 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 CHANGE THE CROSSOVER “OFF/HI/LOW” SWITCH SETTING WITH THE AUDIO SYSTEM ON! The crossover 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.
If your amplifier does not appear to be working, check the 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. If the green LED turns off and the red LED is lit, this indicates that the protection circuitry (SORT) is engaged.
Trouble Shooting Help Alternator noise--whining sound with engine’s RPM: Check for damaged RCA cables. Check the routing of RCA cables. Check the source unit for proper grounding. Check the gain settings, and turn them down if they are set too high. Poor stereo image or reduced bass response: Check system phasing by turning the balance control from left to right.
