Setup and Installation

Proper installation is crucial for the performance and longevity of your subwoofer. It is highly recommended to have this unit installed by a professional car audio technician.

1. Enclosure Selection

Choose an appropriate sealed or ported enclosure that matches the recommended volume for a 15-inch subwoofer. Consult the subwoofer's Thiele-Small parameters for precise enclosure design.

2. Wiring Connections

The GEN-XX15.4DHE features dual 4-ohm voice coils. You can wire the voice coils in series for an 8-ohm load or in parallel for a 2-ohm load, depending on your amplifier's capabilities. Ensure correct polarity for all connections.

Parallel Wiring (2 Ohms): Connect positive (+) of voice coil 1 to positive (+) of voice coil 2. Connect negative (-) of voice coil 1 to negative (-) of voice coil 2. Then connect the combined positive to the amplifier's positive terminal and the combined negative to the amplifier's negative terminal.
Series Wiring (8 Ohms): Connect positive (+) of voice coil 1 to the amplifier's positive terminal. Connect negative (-) of voice coil 1 to positive (+) of voice coil 2. Connect negative (-) of voice coil 2 to the amplifier's negative terminal.

3. Mounting

Securely mount the subwoofer into the chosen enclosure using appropriate screws. Ensure a tight seal to prevent air leaks, which can degrade sound quality.

Operating Instructions

Once installed, follow these guidelines for optimal operation and to prevent damage to your subwoofer and amplifier.

Break-in Period: Allow a break-in period of approximately 10-20 hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components to loosen up and perform optimally.
Gain Setting: Properly set the gain on your amplifier to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to clipping and damage to the subwoofer.
Crossover Settings: Use a low-pass filter (LPF) on your amplifier or head unit to send only low frequencies to the subwoofer. A typical LPF setting for a subwoofer is between 60Hz and 100Hz.
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 over-excursion at very low frequencies.
Volume Control: Always turn down the volume before turning off your audio system or vehicle.

Maintenance

Your DS18 subwoofer is designed for durability and requires minimal maintenance.

Cleaning: Use a soft, dry cloth to wipe down the subwoofer cone and surround. Avoid using harsh chemicals or abrasive cleaners.
Inspection: Periodically inspect the wiring connections for any signs of corrosion or loose connections. Ensure the mounting screws are still tight.
Environmental Factors: Protect the subwoofer from extreme temperatures, direct sunlight, and excessive moisture.

Troubleshooting

If you experience issues with your subwoofer, refer to the following common problems and solutions.

Problem	Possible Cause	Solution
No Sound from Subwoofer	Loose or incorrect wiring. Amplifier in protect mode or off. Head unit settings incorrect. Blown fuse.	Check all wiring connections for proper polarity and secure fit. Verify amplifier power and protection status. Ensure subwoofer output is enabled and volume is up on head unit. Check and replace any blown fuses in the amplifier or power line.
Distorted Sound	Amplifier gain set too high (clipping). Incorrect crossover settings. Damaged subwoofer.	Reduce amplifier gain until distortion is eliminated. Adjust LPF and subsonic filter settings. Inspect subwoofer cone and surround for physical damage.
Weak Bass Output	Incorrect wiring (e.g., voice coils out of phase). Enclosure too small or leaky. Amplifier underpowered.	Double-check voice coil wiring for correct phase. Verify enclosure volume and seal. Ensure amplifier provides sufficient RMS power for the subwoofer.
