Setup and Installation
Proper installation is crucial for optimal performance and safety. Follow these steps carefully.
1. General Wiring Guidelines
- Power Wire: Connect the 8-gauge power wire from the 8GKIT directly to the positive terminal of the vehicle's battery. Install the AFS fuse holder within 18 inches (45 cm) of the battery.
- Ground Wire: Connect the 8-gauge ground wire from the 8GKIT to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote Turn-On Wire: Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. The LL2BE also provides a 12V output with Signal Sense turn-on.

- Utilize the 100% pure copper wire for all power and ground connections to ensure optimal current delivery.
- Install the AFS fuse holder with the appropriate fuse rating as close to the battery as possible.
- Route the RCA cables away from power wires to prevent noise interference.
- Use the included terminals and zip ties to secure all connections and wiring.
Operating Instructions
SRX600.1V Mono Amplifier Controls
- Level (Gain): Adjust this control to match the output voltage of your head unit or LL2BE. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- Bass EQ: Provides a selectable bass boost to enhance low frequencies. Use sparingly to avoid distortion.
- Subsonic Filter: Filters out extremely low frequencies that are inaudible and can damage subwoofers. Adjust to protect your speakers.
- Crossover Network: Adjust the low-pass filter (LPF) to control the upper frequency limit of the amplifier's output, ensuring only bass frequencies are sent to the subwoofer.
- Remote Level Control: Connect the included remote level control to adjust the subwoofer output level from the driver's seat.
LL2BE Line Output Converter Controls
- Enhance Bass: Adjusts the level of digital bass restoration.
- Main: Controls the output level of the main RCA outputs.
- Sub: Controls the output level of the subwoofer RCA outputs.
- Remote Bass Knob: Provides external control over the subwoofer output level.
Maintenance
- Cleaning: Periodically wipe down the amplifier and LOC with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Connections: Regularly check all power, ground, and signal connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Ventilation: Ensure that the amplifier's heatsink remains clear of obstructions to allow for proper cooling.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Amplifier not turning on | Blown fuse, loose power/ground/remote wire, faulty remote turn-on signal. | Check fuse at battery and on amplifier. Verify all power, ground, and remote connections are secure. Test remote turn-on signal from head unit or LL2BE. |
| No Sound | Loose RCA cables, incorrect gain setting, speaker wires disconnected, amplifier in protect mode. | Check RCA connections. Adjust gain. Verify speaker wire connections. Check amplifier status indicator for protect mode. |
| Distorted Sound | Gain set too high, improper crossover/bass boost settings, poor ground connection, damaged speaker. | Reduce gain. Adjust crossover and bass boost settings. Ensure a solid ground connection. Inspect speakers for damage. |
| Engine Noise / Whining | Poor ground, RCA cables routed near power wires, faulty head unit. | Improve ground connection. Reroute RCA cables away from power wires. Consider a ground loop isolator if necessary. |
