Wiring Connections
- Power Connection: Connect the main power wire (minimum 3 AWG recommended) from the vehicle's battery to the +12V terminal on the amplifier. Ensure an appropriate fuse (4 x 30A) is installed close to the battery.
- Ground Connection: Connect a ground wire of the same gauge as the power wire to the Ground terminal on the amplifier and to a clean, solid metal point on the vehicle's chassis.
- Remote Turn-On: Connect the remote turn-on wire from your head unit to the Remote terminal on the amplifier. Alternatively, utilize the GTO Signal Sense feature if your head unit does not provide a remote output.
- Input Connections:
- Speaker Level Inputs: For OEM integration, connect speaker wires from your factory head unit or amplifier to the 8 speaker-level inputs. The amplifier can sum these signals automatically.
- Preamp Inputs: For aftermarket head units, connect RCA cables from your head unit's preamp outputs to the 6 balanced preamp inputs.
- Speaker Outputs: Connect your speakers and subwoofers to the corresponding speaker output terminals. Pay close attention to polarity (+/-) for all connections.
Initial Settings
Before powering on, ensure all connections are secure. Set initial gain levels to minimum and crossover settings to a neutral position. Refer to the detailed manual for specific tuning instructions for AccuBASS, MILC, and crossover adjustments.
Operating Instructions
Once installed, the LC-5.1300 amplifier is designed for straightforward operation. The primary adjustments are made during the initial setup phase to match your audio system's characteristics.
- Power On/Off: The amplifier will power on automatically when a remote signal is received or when the GTO Signal Sense detects an audio signal. It will power off shortly after the audio signal or remote signal is removed.
- Gain Adjustment: Use the gain controls for each channel to match the output voltage of your head unit. The MILC (Maximum Input Level Control) indicator lights will assist in setting the optimal gain without clipping.
- Crossover Adjustment: Adjust the high-pass, band-pass, and low-pass filters to direct appropriate frequencies to your speakers and subwoofers. This prevents distortion and optimizes sound clarity.
- AccuBASS Control: Fine-tune the AccuBASS feature to restore low-frequency information that may be lost in factory audio systems, providing a fuller bass response.
- Optional Remote Level Control (ACR-1): If connected, the ACR-1 remote allows for convenient, on-the-fly adjustment of the subwoofer level from the driver's seat.
Maintenance
The AudioControl LC-5.1300 amplifier is built for durability and requires minimal maintenance. Following these guidelines will help ensure its longevity:
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- Ventilation: Ensure the amplifier has adequate airflow around its heatsink fins. Do not block ventilation openings. Overheating can lead to reduced performance or damage.
- Connections: Occasionally check all wiring connections to ensure they remain tight and free from corrosion. Loose connections can cause intermittent issues or damage.
- Fuse Replacement: If a fuse blows, replace it only with a fuse of the exact same type and rating (30A). Using an incorrect fuse can damage the amplifier or cause a fire.
Troubleshooting
If you encounter issues with your LC-5.1300 amplifier, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Amplifier Not Turning On | Blown fuse, loose power/ground/remote wire, GTO signal sense not detecting signal. | Check and replace fuses. Verify all power, ground, and remote connections are secure. Ensure head unit is on and providing a signal if using GTO. |
| No Sound Output | Input cables disconnected, speaker wires disconnected, incorrect crossover settings, amplifier in protection mode. | Check RCA/speaker-level input connections. Verify speaker wire connections and polarity. Adjust crossover settings. If in protection, turn off and check for shorts or overheating. |
| Distorted Sound | Gain set too high, MILC indicator active, incorrect crossover settings, speaker impedance mismatch. | Reduce gain levels until MILC indicator is off. Adjust crossovers. Verify speaker impedance matches amplifier's capabilities. |
| Overheating / Protection Mode | Insufficient ventilation, low impedance load, prolonged high volume use. | Ensure proper airflow around the amplifier. Check speaker impedance. Reduce volume or allow amplifier to cool down. |
If the problem persists after attempting these solutions, contact AudioControl customer support or a certified car audio technician.
