Setup and Installation
Proper installation is crucial for the performance and longevity of your amplifier. Follow these steps carefully:
1. Mounting the Amplifier
Choose a secure location that provides sufficient airflow around the amplifier. Avoid mounting it directly on carpet or in enclosed spaces without ventilation. Use the provided mounting hardware to secure the amplifier firmly.
2. Power and Ground Connections
Connect the power cable (1/0 gauge recommended) from the vehicle's battery to the amplifier's B+ terminal. Ensure an inline fuse (not included, but essential) is installed within 18 inches of the battery. Connect a ground cable of the same gauge from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle chassis. The remote turn-on wire should be connected from your head unit's remote output to the amplifier's REM terminal.
3. Audio Input Connections
Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA input jacks. Ensure proper left and right channel connections if applicable, though this is a mono-block amplifier.
4. Speaker/Subwoofer Connections
Connect your subwoofer(s) to the amplifier's speaker output terminals. Pay close attention to polarity (+ to + and - to -). Ensure the total impedance of your connected subwoofers matches the amplifier's stable operating impedance (e.g., 1 ohm, 2 ohms, or 4 ohms).
5. Remote Bass Control (Optional)
Plug the remote bass control knob into the designated port on the amplifier. This allows for convenient adjustment of bass levels from the driver's seat.

Operating Instructions
1. Initial Power-Up
Once all connections are secure, reconnect the vehicle's battery. Turn on your head unit. The amplifier's power indicator LED (green) should illuminate, indicating it is receiving power and operating normally.
2. Adjusting Gain
The gain control on the amplifier matches the output voltage of your head unit to the amplifier's input. Start with the gain set to minimum. Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back it off slightly. This ensures maximum clean output.
3. Crossover Settings
The T1.4000DL features adjustable crossover settings. For subwoofers, set the Low Pass Filter (LPF) to filter out high frequencies, typically between 80Hz and 120Hz, depending on your subwoofer and personal preference. The Subsonic Filter (SSF) should be set just below your subwoofer's port tuning frequency to protect it from playing frequencies too low.
4. Bass Boost
The bass boost control allows you to enhance low frequencies. Use this sparingly and adjust carefully to avoid distortion and potential damage to your subwoofers.
5. LED Indicators
- Green LED: Indicates the amplifier is powered on and operating normally.
- Red LED: Indicates the amplifier is in protection mode due to a fault (e.g., overheating, short circuit, low impedance).
6. RGB LED Lighting System
The amplifier features a 12-point RGB LED lighting system. A switch on the end panel allows you to change the color to several presets, initiate a slow-motion color change, or rapid flashing random colors. During slow-motion color change, a single color can be selected for custom installations.
Maintenance
To ensure the longevity and optimal performance of your Soundstream T1.4000DL amplifier, follow these maintenance guidelines:
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins are free from dust and debris. Blocked fins can lead to overheating.
- Connections: Regularly check all power, ground, remote, and speaker connections to ensure they are tight and free from corrosion. Loose connections can cause performance issues or damage.
- Wiring Inspection: Inspect all wiring for signs of wear, fraying, or damage. Replace any compromised wiring immediately.
Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (No Green LED) | Blown fuse, loose power/ground/remote wire, faulty head unit remote output. | Check inline fuse near battery. Verify all power, ground, and remote connections are secure. Test remote wire for 12V when head unit is on. |
| Protection Mode (Red LED) | Overheating, short circuit in speaker wiring, impedance too low, DC offset. | Allow amplifier to cool down. Check speaker wiring for shorts. Verify speaker impedance matches amplifier's stable rating. Disconnect speakers and check if red LED turns off. |
| No Audio Output | Loose RCA cables, incorrect gain setting, faulty speakers/subwoofers, head unit issue. | Ensure RCA cables are securely connected. Adjust gain. Test speakers/subwoofers with another amplifier. Check head unit output. |
| Distorted Sound | Gain set too high, improper crossover settings, poor quality audio source, damaged speakers. | Reduce gain. Adjust LPF/SSF settings. Test with a different audio source. Inspect speakers for damage. |
| RCA Inputs Stop Receiving Signal | Damaged RCA inputs, internal amplifier fault. | Test with new RCA cables. If problem persists, contact customer support for service. |
