Common wiring configurations for a DVC 4-ohm subwoofer:

• Series Wiring (8 Ohms Total): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then, connect the remaining positive and negative terminals to the amplifier. This configuration results in a higher impedance, drawing less power from the ampživější.
• Parallel Wiring (2 Ohms Total): Connect both positive terminals together and both negative terminals together. Then, connect the combined positive and negative terminals to the amplifier. This configuration results in a lower impedance, drawing more power from the ampzáchranář. Zajistěte, aby vaše amplifier is stable at 2 ohms.

Always refer to your amplifier's manual to determine its stable impedance range before wiring. Use high-quality speaker wire of appropriate gauge for your power levels.

5. Návod k obsluze

5.1 Initial Power-Up and Break-In

After installation, perform an initial power-up at a low volume to confirm all connections are correct and the subwoofer is functioning. Gradually increase the volume and check for any abnormal sounds or distortion.

A break-in period is recommended for new subwoofers. During the first 10-20 hours of use, operate the subwoofer at moderate volume levels. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance, improving long-term performance and reliability.

5.2 AmpNastavení filtru

Správný amplifier settings are crucial for optimal subwoofer performance and protection:

• Nastavení zesílení: Nastavte ampsprávně nastavte zesílení lifieru tak, aby odpovídalo výstupní hlasitostitage of your head unit. Do not use the gain control as a volume knob; it should be set to prevent clipping.
• Nízkopropustný filtr (LPF): Zapněte LPF na vašem amplifier and set it to a frequency typically between 60Hz and 100Hz. This ensures the subwoofer only reproduces low frequencies.
• Subsonický filtr (HPF): Pokud váš amplifier has a subsonic filter (also known as a high-pass filter for subwoofers), set it slightly below your enclosure's tuning frequency (for ported enclosures) or around 20-25Hz (for sealed enclosures) to protect the subwoofer from over-excursion at very low frequencies.
• Zesílení basů: Use bass boost sparingly, if at all. Excessive bass boost can lead to clipping and damage the subwoofer.

6. Údržba

The KICKER L784 Subwoofer requires minimal maintenance. Follow these guidelines to keep it in optimal condition:
