Setup & Installation
Proper installation is crucial for the performance and safety of your subwoofer. If you are not experienced with car audio installations, it is highly recommended to seek professional assistance.
Mounting
The CVP12D4 subwoofer is designed for door mount applications, typically within a sealed or ported enclosure. Ensure the enclosure is robust and properly sized for the subwoofer's specifications. Use the provided installation screws to secure the subwoofer firmly to the enclosure. Verify that there is adequate clearance behind the subwoofer for proper excursion and ventilation.
Wiring Dual Voice Coil Subwoofers
The CVP12D4 features a Dual Voice Coil (DVC) design, offering flexibility in wiring configurations to match your amplifier's impedance requirements. Each voice coil has a 4 Ohm impedance.
- Series Wiring (8 Ohms Total): Connect the positive terminal of Voice Coil 1 to the negative terminal of Voice Coil 2. Then, connect the amplifier's positive output to the positive terminal of Voice Coil 2, and the amplifier's negative output to the negative terminal of Voice Coil 1. This configuration results in an 8 Ohm load.
- Parallel Wiring (2 Ohms Total): Connect the positive terminals of Voice Coil 1 and Voice Coil 2 together. Connect the negative terminals of Voice Coil 1 and Voice Coil 2 together. Then, connect the amplifier's positive output to the combined positive terminals, and the amplifier's negative output to the combined negative terminals. This configuration results in a 2 Ohm load.
Always ensure your amplifier is stable at the chosen impedance. Incorrect wiring can damage both the subwoofer and the amplifier.

Operating Instructions
Once installed, follow these general guidelines for operating your subwoofer:
- Initial Power-Up: Start with your amplifier's gain settings at their lowest. Gradually increase the volume and gain to avoid overdriving the subwoofer.
- Crossover Settings: Use your amplifier's low-pass filter (LPF) to send only low frequencies to the subwoofer. A common starting point is 80-100 Hz.
- Subsonic Filter: If your amplifier has a subsonic filter, enable it and set it slightly below your enclosure's tuning frequency to protect the subwoofer from damaging ultra-low frequencies.
- Break-In Period: Allow a break-in period of several hours of moderate listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the subwoofer cone and surround. Avoid harsh chemicals or excessive moisture.
- Inspection: Periodically inspect the subwoofer for any signs of damage to the cone, surround, or wiring connections.
- Secure Mounting: Ensure the subwoofer remains securely mounted in its enclosure.
Troubleshooting
- No Sound: Check all wiring connections (power, ground, remote, RCA, speaker wires) for proper contact and polarity. Verify amplifier is powered on and not in protect mode.
- Distorted Sound: Reduce amplifier gain or head unit volume. Check for proper crossover settings. Ensure the subwoofer is not overdriven.
- Weak Bass: Verify amplifier gain is set correctly. Check subwoofer wiring for correct impedance match. Ensure enclosure is sealed (if applicable) and properly sized.
- Overheating: Ensure adequate ventilation for the amplifier. Check impedance match between subwoofer and amplifier. Reduce listening levels if the subwoofer or amplifier becomes excessively hot.
