3. Setup and Installation

Proper installation is crucial for the performance and longevity of your amplifier. If you are unsure about any part of the installation process, consult a professional installer.

3.1 Mounting

• The amplifier is designed for freestanding mounting.
• Choose a location that is dry, well-ventilated, and protected from direct sunlight or excessive heat.
• Ensure sufficient space around the amplifier for proper airflow to the heat sink.
• Secure the amplifier firmly using appropriate hardware to prevent movement during operation.

3.2 Wiring Connections

All wiring should be performed with the vehicle's battery disconnected to prevent electrical shorts and damage.

1. Power Connection (B+): Connect a heavy-gauge power cable directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install an appropriate fuse holder with a fuse (not included) within 18 inches of the battery.
2. Ground Connection (GND): Connect a heavy-gauge ground cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
3. Remote Turn-On (REM): Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. This wire signals the amplifier to turn on and off with your audio system.
4. Audio Input (RCA): Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA input jacks.
5. Speaker Output: Connect your subwoofer(s) to the amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for optimal sound. Refer to your subwoofer's specifications for impedance matching.

4. Operating Instructions

Once installed, the amplifier requires minimal user interaction for operation. Adjustments are typically made during the initial setup phase.

4.1 Initial Power-Up

After all connections are made and verified, reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on, indicated by an LED indicator (if present).

4.2 Gain Adjustment

The gain control (often labeled 'Level' or 'Input Sensitivity') matches the amplifier's input sensitivity to the output voltage of your head unit. Start with the gain control at its minimum setting. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's gain until you hear distortion, then back it off slightly until the sound is clear. Avoid setting the gain too high, as this can lead to distortion and potential damage to your speakers.

4.3 Crossover Settings

Monoblock amplifiers are typically used for subwoofers and feature a Low-Pass Filter (LPF). Adjust the LPF to filter out high frequencies, allowing only the bass frequencies to pass through to the subwoofer. The ideal setting depends on your subwoofer and personal preference, typically between 80Hz and 120Hz.

5. Maintenance

The Soundstream SM1.700D amplifier is designed for durability, especially in marine environments. Regular, simple maintenance can help ensure its long-term performance.

• Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth to remove dust and debris. For marine use, gently clean any salt residue with a damp cloth and then dry thoroughly. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Regularly check all wiring connections for tightness and corrosion. Ensure that the power, ground, remote, and speaker wires are securely fastened.
• Ventilation: Ensure that the area around the amplifier remains clear of obstructions to allow for proper heat dissipation from the heat sink.

6. Troubleshooting

If you experience issues with your amplifier, refer to the following troubleshooting guide before contacting support.

• No Power:
  • Check the in-line fuse near the battery.
  • Verify all power (B+), ground (GND), and remote (REM) connections are secure and have proper voltage.
  • Ensure the head unit is turned on and sending a remote signal.
• No Sound:
  • Check RCA input cables for proper connection and damage.
  • Verify speaker wire connections at both the amplifier and the subwoofer.
  • Ensure the head unit's volume is up and not muted.
  • Check amplifier gain settings.
• Distorted Sound:
  • Reduce the amplifier's gain setting.
  • Check for damaged speaker wires or short circuits.
  • Ensure the subwoofer impedance matches the amplifier's capabilities.
• Amplifier Overheating:
  • Ensure adequate ventilation around the amplifier.
  • Check speaker impedance; running too low an impedance can cause overheating.
  • Reduce gain settings.
