Wiring the Dual Voice Coils (DVC)
The DCTOA15D features dual 4 Ohm voice coils, offering flexible wiring options to match your ampImpedanzanforderungen des Verstärkers. Stellen Sie immer sicher, dass Ihr ampDer Verstärker ist bei der gewählten Impedanz stabil.
- Parallelverdrahtung: Connect both positive terminals together and both negative terminals together. This results in a 2 Ohm load (4 Ohm / 2 = 2 Ohm).
- Reihenschaltung: Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining two terminals (one positive, one negative) are then connected to the amplifier. This results in an 8 Ohm load (4 Ohm + 4 Ohm = 8 Ohm).
Use appropriate gauge speaker wire for connections. Ensure all connections are secure and free from shorts.

Bedienungsanleitung
Once installed and wired correctly, follow these guidelines for optimal operation:

- Verstärkungseinstellung: Stellen Sie Ihre amplifier's gain control carefully. Start with the gain at its lowest setting and slowly increase it until you achieve the desired volume without any audible distortion.
- Crossover-Einstellungen: Nutzen Sie Ihre amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical LPF setting for subwoofers is between 80Hz and 120Hz, but this can be adjusted based on your system and preference.
- Einlaufzeit: Allow a break-in period of several hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components to loosen up and perform optimally.
