5. 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.
5.1 Mounting Location
- Choose a location that is dry, well-ventilated, and protected from direct sunlight or excessive heat.
- Ensure the mounting surface is sturdy enough to support the amplifier's weight.
- Allow sufficient space around the amplifier for air circulation to prevent overheating.
5.2 Wiring Connections
All wiring should be performed with the vehicle's battery disconnected.
- Power (12V DC): Connect a heavy-gauge power cable (e.g., 4-gauge or larger, depending on total system power) directly from the positive terminal of the vehicle's battery to the amplifier's '12V DC' terminal. Install an in-line 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 of the vehicle chassis. Ensure a solid electrical connection.
- Remote Turn-On (REM): Connect a smaller gauge wire (e.g., 18-gauge) from the amplifier's 'REM' terminal to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with the head unit.
- Audio Input (RCA or HI-INPUT):
- RCA Input: Connect RCA cables from your head unit's subwoofer or full-range pre-outs to the amplifier's 'L' and 'R' RCA input jacks.
- High-Level Input: If your head unit does not have RCA outputs, use the 'HI-INPUT' terminal. Connect the speaker wires from your head unit's speaker outputs to the corresponding terminals on the high-level input connector.
- Speaker Output: Connect your subwoofer(s) to the amplifier's 'SPEAKER OUT' terminals. Ensure correct polarity (+ to + and - to -). Verify the total impedance of your speaker configuration is within the amplifier's supported range (1 ohm minimum for this model).
6. Operating Instructions
After installation, carefully adjust the amplifier settings for optimal sound performance.
6.1 Initial Setup and Gain Adjustment
- Turn the GAIN control on the amplifier to its minimum (counter-clockwise) position.
- Set your head unit's volume to about 75% of its maximum level.
- Play a dynamic piece of music.
- Slowly increase the GAIN control on the amplifier until you hear distortion, then back it off slightly until the sound is clear.
- The GAIN control is not a volume knob; it matches the amplifier's input sensitivity to the head unit's output voltage.
6.2 Filter Adjustments
- LOW PASS (LPF): This filter allows frequencies below the set point to pass through to the subwoofer. For most subwoofers, a setting between 80Hz and 120Hz is common. Adjust this to blend smoothly with your main speakers.
- SUB SONIC (High-Pass Filter): This filter removes extremely low frequencies that are inaudible and can cause damage to your subwoofer. Set this filter slightly below your subwoofer's resonant frequency or port tuning frequency (typically 20Hz-30Hz).
6.3 Bass Boost
- The BASS BOOST control provides an increase in output at 45Hz. Use this sparingly, as excessive bass boost can lead to distortion and potential damage to your subwoofer. Start at 0dB and increase gradually if desired.
6.4 Remote Level Control
- Connect the remote level control to the 'REM' port on the amplifier's control panel.
- Mount the remote control in a convenient location within reach of the driver.
- This control allows you to adjust the subwoofer output level from the driver's seat without accessing the amplifier directly.
7. Maintenance
The Soundstream PN1.1000D amplifier requires minimal maintenance to ensure long-term performance.
- Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ensure that the amplifier's cooling fins are not obstructed to maintain proper heat dissipation.
8. Troubleshooting
If you experience problems with your amplifier, refer to the following table for common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Amplifier does not turn on (Power LED off) | No power, ground, or remote connection; Blown fuse | Check 12V DC, GND, and REM connections. Verify in-line fuse near battery and fuses on amplifier. |
| Amplifier turns on but no sound | No audio input signal; Speaker wires disconnected; Gain too low | Check RCA or high-level input connections. Verify speaker wiring. Adjust gain setting. |
| Distorted sound | Gain set too high; Improper filter settings; Speaker impedance mismatch | Reduce gain. Adjust LPF/Sub Sonic filters. Verify speaker impedance is 1 ohm or higher. |
| Amplifier overheats (Protection LED on) | Insufficient ventilation; Speaker impedance too low; Prolonged high volume operation | Ensure adequate airflow around amplifier. Check speaker impedance. Reduce volume or allow amplifier to cool. |
| Weak or no bass output | Sub Sonic filter set too high; LPF set too low; Phase issue | Adjust Sub Sonic filter to a lower frequency. Adjust LPF to a higher frequency. Check subwoofer phase setting on head unit if available. |
