Setup and Installation
Proper installation is crucial for the performance and longevity of your amplifier. Follow these general steps:
- Mounting Location: Choose a dry, well-ventilated location for the amplifier, away from direct sunlight or heat sources. Ensure sufficient space for wiring and air circulation.
- Power Connection: Connect the 1/0AWG power cable from the battery (with an inline fuse within 18 inches of the battery) to the amplifier's +12V terminal.
- Ground Connection: Connect the 1/0AWG ground cable from the amplifier's GND terminal to a clean, bare metal point on the vehicle's chassis. The ground point should be as short as possible.
- Remote Turn-On: Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. This turns the amplifier on/off with your head unit.
- Signal Input: Connect your head unit's RCA outputs to the amplifier's RCA inputs. Alternatively, use the high-level inputs if your head unit does not have RCA outputs.
- Speaker Output: Connect your subwoofer(s) to the amplifier's speaker output terminals, observing correct polarity.

FIT+™ Technology: This amplifier features FIT+™ Technology, which accepts up to 40V of input and utilizes full differential inputs to eliminate noise, ensuring a clean signal from your source unit.
Operating the Amplifier
Once installed, you can configure your amplifier for optimal sound performance:
- Gain Setting: Use the Gain-match LEDs on the amplifier to set the input gain correctly. This ensures the amplifier receives an optimal signal level without clipping.
- Low-Pass Filter (LPF): Adjust the variable low-pass filter (40-160 Hz, 24 dB/octave) to control the upper frequency limit of the audio signal sent to your subwoofer.
- Subsonic Filter: Set the subsonic filter (10-80 Hz, 24 dB/octave) to remove extremely low frequencies that are inaudible and can cause damage to your subwoofer.
- KickEQ+™ Parametric Bass Boost: Utilize the KickEQ+™ feature for adjustable bass enhancement. This allows for 0-6 dB bass boost, with a variable center frequency (20-80Hz) and variable bandwidth (1-5) to fine-tune your bass response.
- Smart Bass Remote: The included Smart Bass Remote allows for convenient control of the bass level from your listening position. Connect it to the 'REMOTE BASS' port on the amplifier.

Maintenance
To ensure the longevity and optimal performance of your KICKER amplifier:
- Regularly inspect all wiring connections for tightness and corrosion. Loose connections can lead to poor performance or damage.
- Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ensure the amplifier's cooling fins are not obstructed to allow for proper heat dissipation.
- Avoid placing objects on top of the amplifier that could block ventilation.
Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Amplifier Not Turning On | Blown fuse, loose power/ground/remote wire, faulty remote turn-on signal. | Check inline fuse, verify all power, ground, and remote connections are secure and receiving proper voltage. Test remote wire for 12V when head unit is on. |
| No Sound Output | No input signal, incorrect gain setting, speaker wires disconnected, amplifier in protection mode. | Check RCA/high-level input connections, adjust gain, verify speaker wiring polarity and connection, check amplifier status indicator for protection mode. |
| Distorted Sound | Gain set too high, improper crossover settings, poor ground connection, damaged speaker. | Reduce gain setting, adjust LPF/subsonic filters, ensure solid ground connection, inspect speaker for damage. |
| Amplifier Overheating | Insufficient ventilation, impedance too low, prolonged high-volume use. | Ensure proper airflow around amplifier, verify speaker impedance matches amplifier's capabilities, reduce listening volume or allow amplifier to cool. |
If problems persist after attempting these solutions, please contact KICKER customer support or a qualified installer.
