5. Setup and Installation
Proper installation is critical for the performance and longevity of your amplifier. Follow these steps carefully:
5.1 Mounting Location
Choose a mounting location that is dry, well-ventilated, and away from direct heat sources. Ensure there is enough space around the amplifier for air circulation. Common locations include the trunk, under seats, or behind panels.
5.2 Wiring Connections
Refer to the diagram below for proper wiring connections. Use high-quality, appropriate gauge wiring for all connections.
Image: Rear Panel Connections. This image illustrates the power, ground, remote, fuse, and speaker terminals on the amplifier's rear panel.
- Power (BATT+): Connect a direct wire from the positive terminal of your vehicle's battery to the +12V terminal on the amplifier. Use a fuse holder with the recommended fuse size (3 x 35A) as close to the battery as possible.
- Ground (GND): Connect a short wire (no longer than 3 feet) from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote (REM): Connect a wire from your head unit's remote turn-on output to the REM terminal on the amplifier. This will turn the amplifier on and off with your head unit.
- Input (RCA): Connect your head unit's RCA output to the amplifier's RCA input jacks.
- Speaker Output: Connect your subwoofer(s) to the speaker terminals. Ensure correct polarity (+ to + and - to -). This amplifier supports 1 Ohm, 2 Ohm, and 4 Ohm speaker impedance.
- Remote Bass Knob: Plug the remote bass knob cable into the 'REMOTE' port on the amplifier. Mount the knob in a convenient location for easy access.
6. Operating Instructions
Once installed, adjust the amplifier settings for optimal sound performance.
Image: Top Panel Controls. This image highlights the gain, bass boost, boost frequency, low pass filter (LPF), and phase controls on the amplifier's top panel.
6.1 Gain Control (Input Sensitivity)
The Gain control matches the amplifier's input sensitivity to the output of your head unit. Start with the gain set to minimum (MIN). Gradually increase the gain until you hear slight distortion, then back off slightly. This ensures maximum clean signal output.
6.2 Low Pass Filter (LPF)
The LPF control allows you to set the upper frequency limit for the amplifier's output, typically for subwoofers. Adjust this between 50Hz and 150Hz to blend the subwoofer's output with your main speakers.
6.3 Bass Boost
The Bass Boost control provides an adjustable boost at a specific frequency (40Hz or 100Hz). Use this to enhance bass response. Start at 0dB and increase gradually if desired, being careful not to over-boost and cause distortion.
6.4 Phase Control
The Phase control (0° or 180°) helps to align the subwoofer's output with the rest of your audio system. Experiment with both settings to find the one that provides the most impactful and coherent bass response.
6.5 Remote Bass Knob
The included remote bass knob allows for convenient, real-time adjustment of the subwoofer's output level from the driver's seat.
7. Maintenance
Regular maintenance helps ensure the longevity and performance of your amplifier.
- Cleaning: Use a soft, dry cloth to wipe down the amplifier's exterior. Do not use harsh chemicals or abrasive cleaners.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Ventilation: Ensure that the amplifier's cooling fins are free from dust and debris to maintain proper heat dissipation.
8. Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / No Indicator Light | Blown fuse, poor power/ground connection, no remote signal. | Check amplifier fuses and inline fuse near battery. Verify +12V, GND, and REM connections are secure and receiving power. |
| No Sound Output | RCA cables disconnected/damaged, speaker wires disconnected/shorted, gain set too low. | Check RCA connections from head unit. Verify speaker wire connections and ensure no shorts. Increase gain slowly. |
| Distorted Sound | Gain set too high, improper LPF setting, poor ground connection. | Reduce gain. Adjust LPF. Check ground connection for tightness and cleanliness. |
| Amplifier Overheating (Protection Mode) | Insufficient ventilation, impedance too low, prolonged high output. | Ensure adequate airflow around amplifier. Verify speaker impedance matches amplifier's capabilities. Reduce volume or allow amplifier to cool. |
If the problem persists after checking these points, please contact DS18 customer support or an authorized service center.
