Dual 4 Ohm Wiring Options:

• Parallel Wiring (2 Ohm Load): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect the combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This configuration results in a 2 Ohm load.
• Series Wiring (8 Ohm Load): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive terminal to the amplifier's positive output and the remaining negative terminal to the amplifier's negative output. This configuration results in an 8 Ohm load.

Always ensure correct polarity to prevent phase issues and ensure optimal sound quality.

5. Operation

5.1 Initial Power-Up and Break-in

After installation, gradually increase the volume during the first few hours of use. This 'break-in' period allows the subwoofer's suspension components to loosen and settle, leading to improved performance and longevity. Avoid playing the subwoofer at maximum volume or with excessive bass boost during this initial phase.

5.2 Amplifier Settings

• Gain Setting: Adjust the amplifier's gain control to match the output voltage of your head unit. This is not a volume control; it sets the sensitivity of the amplifier. Incorrect gain settings can lead to distortion and damage.
• Low-Pass Filter (LPF): Set the LPF on your amplifier or head unit to filter out high frequencies from reaching the subwoofer. A common range is 60-100 Hz, but this can vary based on your system and preferences.
• Subsonic Filter: If available, set the subsonic filter to protect the subwoofer from playing frequencies below its resonant frequency (Fs: 37.0 Hz), which can cause excessive excursion and damage.

6. Maintenance

Regular maintenance helps ensure the continued performance and appearance of your subwoofer.

• Cleaning: Use a soft, dry cloth to gently wipe down the subwoofer cone and surround. Avoid using harsh chemicals or excessive moisture.
• Inspection: Periodically check all wiring connections for tightness and corrosion. Inspect the subwoofer's surround and cone for any signs of damage or wear.
• Environmental Protection: Ensure the subwoofer is protected from direct sunlight, extreme temperatures, and moisture, which can degrade materials over time.
