Common wiring configurations for dual voice coil subwoofers:

• Series Wiring (for a single subwoofer): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals will present an 8-Ohm load.
• Parallel Wiring (for a single subwoofer): Connect both positive terminals together and both negative terminals together. This will present a 2-Ohm load.
• Pelbagai Subwoofer: When using multiple subwoofers, further series or parallel connections can be made to achieve the desired final impedance. Always ensure the final impedance matches your amplifier's stable operating range.

  • Sahkan ampPengaktif dihidupkan dan menerima isyarat.
  • Semak amplifier fuses and system fuses.
• Bunyi Herot:
  • Kurangkan amplifier gain or head unit volume. Distortion often indicates the ampliifier sedang keratan.
  • Check for proper impedance matching between the subwoofer and amplebih hidup.
  • Ensure the subwoofer is securely mounted and not vibrating against the enclosure.
• Bass Lemah atau Terkedu:
  • Verify the subwoofer is wired in phase with other speakers in the system.
  • Check crossover settings on the amplifier or head unit. Ensure the low-pass filter is set appropriately for a subwoofer.
  • Confirm the enclosure volume and tuning are suitable for the subwoofer.
• Terlalu panas:
  • Pastikan pengudaraan yang mencukupi di sekeliling amplebih hidup.
  • Reduce prolonged high-volume listening.
  • Check for proper impedance matching. Incorrect impedance can cause the amplifier to work harder and overheat.

If these steps do not resolve the issue, contact DD Audio customer support or a qualified technician.
