Introduction KX.1 Series Amplifier Owner’s Manual Mono-Block Models: KX400.1 / KX600.1 / KX1200.1 Congratulations! Attention: 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. You have just purchased the latest in amplifier technology to carry the famous KICKER name. Your KICKER KX.
Class D Mono Amplifier Delivers massive power into a PAST (PRE Amp Signal Transfer) Output RCA jacks to pass the single channel with greater efficiency than conventional class A/B amplification. incoming signal to another amplifier or component. Low Impedance Operation Designed for stable operation maximum power transfer and clamping. and maximum power output into a 2 ohm load (KX400.1, KX600.1) and into an amazing 1 ohm load (KX1200.1).
Remove Installation Mounting Remove 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 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 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. Connecting to the amp with either input will provide a low level signal at the output (PAST) jacks. Left + Left Right Right + The ground should be connected to the amplifier first before making any of the other connections.
STRAPPING TWO KX.1 AMPS(DOUBLE POWER) Installation System Diagram The following diagrams show the most common configurations for your Kicker KX.1 series amplifier. ONE CHANNEL OPERATION KX.1 series amplifiers are capable of operating into a minimum impedance of 2 ohm for the KX400.1, KX600.1 and 1 ohm for the KX1200.1. SIGNAL OUT By using a Mono plug (available at Radio Shack) you can run two KX.1 amplifiers into one woofer. Minimum impedance 4 ohm for KX400.1, KX600.1 and 2 ohm for the KX1200.1.
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. Mounting Surface Most head units with high voltage outputs should be capable of driving up to ten amplifiers in a chain.
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. SUBSONIC FILTER SWITCH NEVER CHANGE THE SUBSONIC FILTER SWITCH SETTING WITH THE SYSTEM ON! The switch located on the end panel next to the RCA jacks is for the subsonic filter. It is 12db/octave set at 25 Hz. All KX.
If your amplifier does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, crossover switch set properly, gain controls properly set, 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.
