3.4 Instrucións de cableado
Follow these steps carefully for wiring the system. Refer to the wiring diagram below for visual guidance.
- Power Wire (Red 4 AWG): Run the 17 ft red power wire from the vehicle's positive battery terminal to the fuse holder, then from the fuse holder to the +12V terminal on the DS18 amplifier. Ensure the fuse holder is installed close to the battery (within 18 inches).
- Ground Wire (Black 4 AWG): Connect the 3 ft black ground wire from the GND terminal on the ampo adaptador a unha superficie metálica limpa e sen pintar no chasis do vehículo. Asegúrese de que haxa unha boa conexión eléctrica.
- Cable de acendido remoto: Connect the remote wire from your head unit's remote output to the REM terminal on the amplifier. This wire turns the ampacende e apaga o activador coa unidade principal.
- Cables RCA: Connect the RCA cables from your head unit's subwoofer output (or full-range output if no dedicated sub output) to the RCA input jacks on the DS18 ampmáis vivo.
- Cable do altofalante: Conecte o cable do altofalante do amplifier's speaker output terminals to the KICKER subwoofer enclosure's input terminals. Ensure correct polarity (+ to + and - to -). The KICKER 48TRTP122 enclosure has a 2-ohm impedance.

4. Instrucións de funcionamento
Once the system is installed, follow these steps to configure and operate your subwoofer and ampmáis vivo.
4.1 Initial Power-Up and Gain Setting
- Volva conectar o terminal negativo da batería do vehículo.
- Acenda a unidade principal. O amplifier should power on (indicated by a blue LED on the ampmáis vivo).
- Establece o amplifier's GAIN control to its minimum (fully counter-clockwise) position.
- Play a music track with strong bass at a moderate volume level on your head unit (around 75% of maximum volume).
- Aumente lentamente o control de GANANCIA no amplifier until you hear distortion, then back it off slightly until the sound is clear. This sets the maximum clean output level.
4.2 Amplifier Controls (DS18 CANDY-X1B)
The DS18 CANDY-X1B amplifier features several controls for fine-tuning your bass output:
- GAÑA: Axusta a sensibilidade de entrada para que coincida coa saída da unidade principal. (Consulta 4.1)
- BASS BOOST (0-18 dB): Increases the bass output at a specific frequency (typically around 45 Hz). Use sparingly to avoid distortion and speaker damage.
- LPF (Low-Pass Filter) (50-150 Hz): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust to blend the subwoofer's output seamlessly with your main speakers.
- SUBSONIC FILTER (10-55 Hz): Filters out extremely low frequencies that are inaudible and can cause damage to the subwoofer. Set it slightly below your subwoofer's lowest usable frequency.
- PHASE (0/180 degrees): Adjusts the phase of the subwoofer output relative to your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass.
- REMOTO: Port for connecting the wired bass remote control, allowing convenient bass level adjustment from the driver's seat.
