4. Configuración e instalación
4.1 Montaxe
Escolla unha localización de montaxe que proporcione unha ventilación axeitada para o amplificador. O amplifier should be securely fastened to a solid surface to prevent movement during vehicle operation. Avoid mounting the amplifier directly on carpet or in areas prone to excessive heat or moisture.
4.2 Conexións de cableado
Refer to the diagram below for proper wiring connections. Ensure all connections are secure and insulated to prevent short circuits.

- Potencia (BATERÍA +12 V): Connect to the positive terminal of your vehicle's battery using an appropriate gauge power wire. An inline fuse (not included) must be installed within 18 inches (45 cm) of the battery.
- Terra (GND): Connect to a clean, solid metal point on the vehicle's chassis. Ensure the connection point is free of paint or rust.
- Remoto (REM): Connect to the remote turn-on lead from your head unit. This signal turns the ampactivar e desactivar o activador co teu sistema de son.
- Entrada (RCA): Conecta as saídas RCA da unidade principal ao amplifier's RCA inputs. The amplifier also supports high-level input via the same RCA jacks using Kicker's FIT technology.
- Saída do altofalante: Conecte o(s) seu(s) subwoofer(es) ao amplifier's speaker terminals. Observe correct polarity (+ to + and - to -). The KX400.1 is a mono amplifier, designed for a single subwoofer or multiple subwoofers wired to a compatible impedance.
- Graves remotos: This port is for an optional wired remote bass control (sold separately) to adjust bass levels from the driver's seat.
4.3 Controisview
The Kicker KX400.1 features several controls for fine-tuning your audio system. These controls are located on the front panel of the ampmáis vivo.

- GAÑA: Axusta a sensibilidade de entrada do amplifier to match the output of your head unit.
- SUB-SONIC: A high-pass filter that removes ultra-low frequencies below the audible range, protecting your subwoofer from over-excursion.
- LO-PASS X-OVER: A low-pass filter that allows only frequencies below the set point to pass through to the subwoofer. Adjustable from 40 Hz to 160 Hz.
- KICK EQ+: Kicker's variable bass boost with adjustable center frequency and bandwidth.
- CENTER FREQ: Selects the frequency point for the bass boost.
- ANCHO DE BANDA: Adjusts the Q-factor or width of the boost around the center frequency.
- IMPULSO: Controls the amount of bass boost (0 dB to +18 dB).
- PRT (Protection) Indicator: Ilumina cando o amplifier is in protection mode due to overheating, low voltage, or short circuit.
5. Operating and Tuning
5.1 Initial Setup and Gain Matching
- Xire o amplifier gain all the way down (counter-clockwise).
- On your head unit, turn the volume up to about 75% of its maximum level.
- Slowly increase the gain on the amplifier until you hear slight distortion, then back it off slightly until the sound is clear.
- For optimal performance, it is recommended to use a test tone and an oscilloscope for precise gain matching.
5.2 Crossover and Subsonic Filter Adjustment
- LO-PASS X-OVER: Adjust this filter to match the frequency response of your subwoofer and the rest of your audio system. A common starting point is 80 Hz.
- SUB-SONIC: Set the subsonic filter slightly below the tuning frequency of your ported subwoofer enclosure (if applicable) or around 25-30 Hz for sealed enclosures to protect the subwoofer from damaging ultra-low frequencies.
5.3 KickEQ+ Tuning
The KickEQ+ allows you to boost specific bass frequencies. Use it sparingly to enhance bass without introducing distortion.
- IMPULSO: Start with 0 dB boost and increase gradually.
- CENTER FREQ: Experiment with different frequencies to find the one that best enhances your subwoofer's output in your vehicle.
- ANCHO DE BANDA: Adjust the width of the boost. A narrower bandwidth (higher Q) will affect a smaller range of frequencies, while a wider bandwidth (lower Q) will affect a broader range.
6. Mantemento
The Kicker KX400.1 ampO lifer require un mantemento mínimo. Siga estas pautas para garantir a súa lonxevidade:
- Limpeza: Limpar periodicamente o ampo exterior do lifador cun pano suave e seco. Non empregue produtos químicos agresivos nin produtos de limpeza abrasivos.
