4. Setup and Installation
4.1 General Installation Guidelines
- Choose a mounting location that is dry, well-ventilated, and protected from physical damage.
- Ensure adequate space around the amplifier for proper cooling.
- Securely mount all components to prevent movement during vehicle operation.
- Route power cables away from signal cables to minimize noise.
4.2 KISL K-Series Interconnect Installation
The Kicker 46KISL K-Series Interconnect allows for easy connection of factory speaker wires to your amplifier's RCA inputs. This eliminates the need for a separate line-out converter when using a factory head unit.
- Identify the factory speaker wires from your vehicle's head unit or factory amplifier.
- Connect the appropriate speaker wires to the bare wire ends of the KISL interconnect. Ensure correct polarity.
- Plug the RCA ends of the KISL interconnect into the corresponding RCA input jacks on the LX1200.5 amplifier.

4.3 KEYLOC Key Series Smart Powered Line-Out Converter Installation
The Kicker 47KEYLOC provides a revolutionary line-out conversion with automatic frequency detection, ideal for integrating with complex factory audio systems. It offers versatile input sensitivity from 1V to 40V (Hi-level) and 125mV to 10V (Lo-level).
- Connect the factory speaker wires to the high-level inputs of the KEYLOC converter.
- Connect the RCA outputs of the KEYLOC to the RCA inputs of the LX1200.5 amplifier.
- Provide power and ground connections to the KEYLOC as per its specific instructions (refer to the KEYLOC manual for detailed wiring).
- The KEYLOC will automatically detect and optimize the frequency response for a clean signal.

4.4 LX1200.5 5-Channel Amplifier Installation
The LX1200.5 amplifier features a compact design and FIT+ technology for noise-free playback. It accepts both low- and high-level signals up to 40V.
- Power Wiring: Connect a fused power cable directly from the vehicle's battery to the amplifier's +12V terminal. Ensure the fuse is located within 18 inches of the battery.
- Ground Wiring: Connect a ground cable of the same gauge as the power cable from the amplifier's GND terminal to a clean, bare metal chassis point on the vehicle.
- Remote Turn-On: Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal.
- Signal Input: Connect the RCA outputs from your head unit, KISL, or KEYLOC to the amplifier's RCA input jacks. The amplifier supports both low-level (RCA) and high-level (speaker wire) inputs.
- Speaker Output: Connect your speakers and subwoofer to the amplifier's speaker output terminals. Pay close attention to polarity and impedance ratings. The LX1200.5 delivers 175W x 4 @ 2Ω and 700W @ 1Ω for the sub channel.
- Mounting: Securely mount the amplifier using the provided hardware in your chosen location.

5. Operating Instructions
5.1 LX Control Center
The LX Control Center provides real-time monitoring of critical amplifier parameters, including battery voltage and amplifier temperature. This helps ensure optimal performance and protection.
5.2 LX Remote Control
The included LX Remote Control allows for convenient adjustment of bass levels from the driver's seat. It also features SHOCwave2.0 technology for digital bass restoration, enhancing low-frequency response.
5.3 Gain-Match LEDs
The amplifier features Gain-Match LEDs to assist in setting input gain levels correctly. Adjust the gain until the LED indicates optimal signal without clipping, ensuring dynamic audio performance and preventing distortion.
5.4 Adjustable Crossovers
The LX1200.5 includes adjustable crossovers for precise audio tuning. These allow you to filter specific frequency ranges to your speakers and subwoofer, optimizing sound quality and protecting your components.
5.5 RGB LED Accent Colors
Customize the amplifier's aesthetic with 11 selectable RGB LED accent colors. Refer to the amplifier's specific controls or software (if applicable) for changing these settings.
6. Maintenance
The Kicker LX1200.5 amplifier requires minimal maintenance. Periodically inspect all wiring connections to ensure they are secure and free from corrosion. Keep the amplifier's cooling fins clear of dust and debris to maintain proper heat dissipation. Clean the exterior with a soft, dry cloth. Do not use harsh chemicals or abrasives.
7. Troubleshooting
- No Power: Check the main fuse near the battery, the amplifier's internal fuses, and all power/ground connections. Ensure the remote turn-on wire is receiving +12V when the head unit is on.
- No Sound: Verify all RCA and speaker connections. Check head unit settings and amplifier gain levels. Ensure speakers are properly wired and functional.
- Distorted Sound: Reduce the amplifier's gain setting. Check for proper crossover settings. Ensure speaker impedance matches the amplifier's capabilities. Inspect speaker wires for shorts.
- Amplifier Overheating: Ensure adequate ventilation around the amplifier. Check speaker impedance. Reduce gain levels if consistently overheating.
- Noise/Hiss: Reroute power and signal cables to prevent interference. Check ground connections for cleanliness and security.
