Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Soundstream Reserve Series RS1.8000D Class D Monoblock Subwoofer Amplifier. Please read this manual thoroughly before attempting installation or operation to ensure proper use and to achieve optimal performance from your audio system. Retain this manual for future reference.
Safety Information
Always observe the following safety precautions to prevent injury or damage to the amplifier or vehicle:
- Disconnect the vehicle's negative battery terminal before beginning any installation.
- Ensure all wiring is properly routed and secured to prevent pinching or damage.
- Use appropriate gauge wiring for power, ground, and speaker connections as specified in the installation section.
- Avoid mounting the amplifier in areas exposed to direct sunlight, excessive heat, moisture, or dust.
- Do not open the amplifier casing. There are no user-serviceable parts inside. Refer all servicing to qualified personnel.
- Ensure the amplifier is adequately ventilated to prevent overheating.
Features
The Soundstream Reserve Series RS1.8000D amplifier incorporates advanced design and technology to deliver powerful and clear bass reproduction:
- Class D Amplifier Technology: Provides high efficiency and significant power output while minimizing strain on the vehicle's electrical system.
- Adjustable Low-Pass Filter: Allows precise tuning of the upper frequency limit for the subwoofer.
- Adjustable Subsonic Filter: Filters out ultra-low frequencies below the audible range to protect subwoofers and improve sound quality.
- Phase Switch: Enables adjustment of the subwoofer's phase (0° or 180°) to optimize integration with other speakers.
- Wired Remote Bass Level Control: Provides convenient adjustment of subwoofer output from the driver's seat.
Setup and Installation
Proper installation is crucial for optimal performance and safety. If you are unsure about any part of the installation process, consult a professional car audio installer.
Mounting the Amplifier
Choose a secure, dry location with adequate ventilation. Avoid mounting on carpet or in enclosed spaces without airflow. Ensure the mounting surface is strong enough to support the amplifier's weight.

Wiring Connections
- Power (B+): Connect a heavy-gauge power cable (e.g., 4 AWG or larger, depending on system requirements) directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install an appropriate fuse holder within 18 inches of the battery.
- Ground (GND): Connect a heavy-gauge ground cable of the same size as the power cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote (REM): Connect a smaller gauge wire (e.g., 18 AWG) from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your stereo.
- RCA Input: Connect RCA cables from the subwoofer pre-out of your head unit to the amplifier's RCA input jacks.
- Speaker Output: Connect your subwoofer(s) to the amplifier's speaker output terminals. Ensure correct polarity (+ to + and – to –). Refer to your subwoofer's specifications for impedance matching.
- Remote Bass Control: Connect the wired remote bass control to the designated port on the amplifier. Mount the remote in a convenient location for adjustment.
Operating Instructions
Once the amplifier is installed and wired, follow these steps for initial setup and operation:
Initial Power-Up
- Double-check all wiring connections.
- Reconnect the vehicle's negative battery terminal.
- Turn on your head unit. The amplifier's power indicator should illuminate.
Adjusting Controls
- Gain Control: Start with the gain control at its minimum setting. Play a familiar track with strong bass. Slowly increase the gain until you hear distortion, then back off slightly. This matches the amplifier's input sensitivity to your head unit's output.
- Low-Pass Filter (LPF): Adjust the LPF to cut off frequencies above your desired subwoofer range, typically between 80Hz and 120Hz. This ensures the subwoofer only plays bass frequencies.
- Subsonic Filter: Set the subsonic filter to protect your subwoofer from playing frequencies below its resonant frequency, usually around 20Hz to 30Hz.
- Phase Switch: Experiment with the 0° and 180° settings to find the position that provides the most impactful and cohesive bass response with your front speakers.
- Remote Bass Control: Use the wired remote to make fine adjustments to the subwoofer's output level from your listening position.
Maintenance
The Soundstream RS1.8000D amplifier requires minimal maintenance:
- Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Keep the amplifier clean by wiping it with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure that the amplifier's cooling fins are free from dust and debris to maintain proper heat dissipation.
Troubleshooting
If you experience issues with your amplifier, consult the following table before contacting support:
| Problem | Possible Cause | Solution |
|---|---|---|
| Amplifier does not turn on | No power, ground, or remote signal; Blown fuse | Check power, ground, and remote wire connections. Verify fuse at battery and on amplifier. |
| No sound output | RCA cables disconnected; Speaker wires disconnected; Gain too low | Check RCA and speaker connections. Increase gain setting. |
| Distorted sound | Gain set too high; Improper filter settings; Damaged speaker | Reduce gain. Adjust LPF/Subsonic filters. Inspect speaker for damage. |
| Amplifier overheats | Insufficient ventilation; Improper impedance load | Ensure adequate airflow around amplifier. Verify speaker impedance matches amplifier's capabilities. |
