Features Radically Advanced Chassis with removable shroud and improved heatsink technology. The heatsinks provide the amplifier with longer runtime, improved reliability and performance. The height has been decreased for more versatile installations. For those Livin Loud , the shrouds may be painted to match your car! Low Impedance Operation The KX series amplifiers are stable down to 2 Ohm stereo and 4 Ohm mono. This will allow the installer flexibility when designing the system. It will be ea

Features cont. Custom tooled gold plated connectors Assure maximum power transfer and damping. SAMS (Stereo And Mono Simultaneously) Amplifier will operate into a bridged mono load and a stereo load at the same time. This type of system is great if the consumer is just starting out, or on a tight budget. Three Year Warranty When youre Livin Loud you want the tunes to roll non-stop and we couldnt agree more. When you purchase your KX Amplifier from an authorized KICKER dealer we back it up

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 Remove Remove damaged by the screws. Check for wiring, brake lines, fuel lines, gas tanks, etc. All amplifiers generate heat under normal opera- tion. Be sure to choose a location that allows ade- quate ventilation for the amplifier. Also consider that the air temperature inside an automobiles trunk can reach upwards of 140 de

Wiring cont. 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.

Adjusting Amplifier Controls On your Kicker amplifier there are rotary controls and switches on the end panel. These controls ensure the relia- bility and performance of the amplifier, so they need to be set correctly. If you are using a KX150.4 you will have two sets of rotary controls and switches. One set controls AMP1 and one set controls AMP2. BEFORE TURNING ON THE

Adjusting Amplifier Controls cont. Crossover Control Where you set the crossover is very subjective and can be fine tuned to match your listening preference or speaker requirement. If the amplifier is driving small speakers (crossover set to HI PASS) this will eliminate the low frequencies from damaging the high frequency speaker. If the amplifier is driving subwoofers (crossover set to LO PASS). These are only guidelines because setting the right frequency depends on the listeners preferences.
