Setup
1. Enclosure Selection and Mounting
The T5.152 subwoofer requires a suitable enclosure for optimal performance. Consult with an audio professional or use recommended enclosure designs for sealed or ported applications. The top-mount depth of the subwoofer is 9.25 inches, which should be considered when designing or selecting an enclosure.
- Ensure the mounting surface is rigid and free from obstructions.
- Use appropriate fasteners to secure the subwoofer firmly into the enclosure.
- Apply the provided hole covers to unused mounting holes for a clean finish.
2. Wiring Connections
The T5.152 features dual 2-ohm voice coils, offering flexibility in wiring configurations to match your amplifier's impedance requirements. Common configurations include:
- 1 Ohm Load: Wire the two 2-ohm voice coils in parallel. This configuration draws more current and requires an amplifier stable at 1 ohm.
- 4 Ohm Load: Wire the two 2-ohm voice coils in series. This configuration is suitable for amplifiers stable at 4 ohms.
Refer to your amplifier's manual for compatible impedance loads. Always ensure correct polarity (+ to + and - to -) for all connections.

3. Amplifier Integration
Connect the subwoofer to a dedicated amplifier capable of supplying the recommended RMS power (1300 watts) at the chosen impedance. Use high-quality RCA cables for signal transfer from your head unit to the amplifier, and appropriate gauge speaker wire from the amplifier to the subwoofer.
Operating Instructions
1. Initial Power-Up and Break-In
After installation, perform an initial power-up at low volume levels. Allow the subwoofer to break in for approximately 10-20 hours of play time at moderate volumes. This allows the suspension components to loosen, leading to optimal performance.
2. Amplifier Settings
Adjust your amplifier's settings for optimal performance and to prevent damage:
- Gain Control: Set the gain to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to clipping and damage.
- Low-Pass Filter (LPF): Set the LPF to filter out frequencies above the desired bass range, typically between 60Hz and 100Hz.
- Subsonic Filter: If available, set the subsonic filter to protect the subwoofer from playing frequencies below its resonant frequency, usually around 20Hz to 30Hz.
- Bass Boost: Use bass boost sparingly and with caution. Excessive bass boost can cause distortion and damage.
3. Listening Levels
While the T5.152 is designed for high output, prolonged listening at extremely high, distorted volumes can cause damage. Listen for signs of distortion and reduce volume or adjust settings if distortion occurs.
Maintenance
The Soundstream T5.152 subwoofer requires minimal maintenance:
- Regularly inspect the cone and surround for any signs of damage or wear.
- Keep the subwoofer free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure all wiring connections remain secure and free from corrosion.
- Avoid placing heavy objects on the subwoofer cone.
Troubleshooting
If you experience issues with your subwoofer, consult the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from subwoofer | No power to amplifier; loose speaker wires; incorrect amplifier settings; damaged subwoofer. | Check amplifier power and ground connections; verify speaker wire connections and polarity; adjust amplifier gain and filter settings; test subwoofer with another amplifier if possible. |
| Distorted or unclear bass | Amplifier gain too high (clipping); incorrect LPF setting; damaged voice coil; poor enclosure design. | Reduce amplifier gain; adjust LPF to appropriate frequency; inspect subwoofer for physical damage; ensure enclosure meets specifications. |
| Subwoofer cuts out intermittently | Loose wiring connections; amplifier overheating; impedance mismatch. | Secure all wiring; ensure adequate ventilation for amplifier; verify correct impedance wiring for the amplifier. |
