The DS18 CANDY-X1B amplifier features several controls for fine-tuning your bass output:
- DOBITAK: 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.

- 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.
- DALJINSKO: Port for connecting the wired bass remote control, allowing convenient bass level adjustment from the driver's seat.
