3.4 Instruccions de cablejat
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 ampel adaptador a una superfície metàl·lica neta i sense pintar del xassís del vehicle. Assegureu-vos d'una bona connexió elèctrica.
- Cable d'encesa remota: Connect the remote wire from your head unit's remote output to the REM terminal on the amplificador. Aquest cable fa que el ampengegueu i apagueu l'activador amb la unitat 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 ampmés viu.
- Cable de l'altaveu: Connecteu el cable de l'altaveu del 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.
- Comandament de baix: Connect the included bass remote to the dedicated remote port on the DS18 amplifier. Mount the remote in an accessible location for easy adjustment.

4. Instruccions de funcionament
Once the system is installed, follow these steps to configure and operate your subwoofer and ampmés viu.
4.1 Engegada inicial i configuració del guany
- Torneu a connectar el terminal negatiu de la bateria del vehicle.
- Engegueu la unitat principal. El amplifier should power on (indicated by a blue LED on the ampmés viu).
- Estableix el 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).
- Slowly increase the GAIN control on the 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:
- GUANY: Adjusts the input sensitivity to match the output of your head unit. (See 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.
- COMANDAMENT: Port for connecting the wired bass remote control, allowing convenient bass level adjustment from the driver's seat.

5. Manteniment
Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre sistema d'àudio.
- Neteja: Keep the subwoofer enclosure and amplifier clean and free of dust and debris. Use a soft, dry cloth. Avoid liquid cleaners directly on components.
- Connexions: Comproveu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben ajustades i que no estiguin corroses. Les connexions soltes poden provocar un rendiment deficient o danys.
- Ventilació: Assegureu-vos el amplifier's cooling fins are not obstructed to prevent overheating.
- Comprovació de fusibles: Si el amplifier does not power on, check the fuse in the fuse holder near the battery. Replace with a fuse of the same rating (100A Mini ANL).
