Setup and Installation
Proper installation is crucial for the performance and safety of your subwoofer. If you are unsure about any steps, consult a professional car audio installer.
1. Enclosure and Mounting
The IX-8 D2 subwoofer requires a suitable enclosure for optimal sound reproduction. Ensure the enclosure is robust and properly sealed. The subwoofer has a mounting depth of 4.17 inches. Verify that your chosen enclosure provides adequate clearance for the subwoofer's depth and diameter.

When mounting the subwoofer, ensure all mounting screws are tightened securely and evenly to prevent air leaks and vibrations. Use appropriate gaskets or sealants if necessary.
2. Wiring Configurations
The IX-8 D2 features dual 2-ohm voice coils, offering flexibility in wiring to achieve different impedance loads for your amplifier. Always match the subwoofer's final impedance to your amplifier's stable operating impedance.

- 4 Ohm Load (Series Wiring): 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 a 4-ohm load.
- 1 Ohm Load (Parallel Wiring): Connect both positive terminals of the voice coils together, and connect both negative terminals of the voice coils together. Then, connect the combined positive terminals to the amplifier's positive output and the combined negative terminals to the amplifier's negative output. This configuration results in a 1-ohm load.
Ensure all connections are secure and properly insulated to prevent short circuits.
Operating Instructions
1. Power Handling
The Skar Audio IX-8 D2 has an RMS power rating of 150 Watts and a Peak power rating of 300 Watts. It is essential to use an amplifier that can provide power within these specifications to avoid damage to the subwoofer. Underpowering or overpowering can lead to distortion and premature failure.
2. Break-in Period
Allow a break-in period of approximately 20-30 hours of normal listening at moderate volumes before pushing the subwoofer to its maximum capabilities. This allows the suspension components to loosen and settle, leading to optimal performance and extended lifespan.
3. Amplifier Settings
Adjust your amplifier's gain, crossover, and bass boost settings carefully. Start with low gain and gradually increase it until you achieve the desired volume without distortion. Set the low-pass filter (LPF) to prevent high frequencies from reaching the subwoofer, typically between 80-120 Hz. Avoid excessive bass boost, as this can lead to clipping and damage.
Maintenance
To maintain the performance and appearance of your subwoofer:
- Keep the subwoofer clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the subwoofer to extreme temperatures or direct sunlight for prolonged periods.
- Regularly check wiring connections for tightness and corrosion.
Troubleshooting
If you experience issues with your subwoofer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose wiring, amplifier off, incorrect impedance, blown fuse. | Check all connections, ensure amplifier is powered on, verify impedance match, inspect fuses. |
| Distorted Sound | Gain too high, incorrect crossover settings, overpowering, damaged voice coil. | Reduce amplifier gain, adjust LPF, ensure power matches RMS rating, inspect subwoofer for damage. |
| Overheating Amplifier | Incorrect impedance load, insufficient ventilation, amplifier gain too high. | Verify impedance match, ensure proper airflow around amplifier, reduce gain. |
If the problem persists after checking these points, contact Skar Audio customer support or a qualified technician.
