4. Setup and Installation
4.1 AudioControl LC5iPRO Installation
The LC5iPRO is designed to convert high-level speaker signals from a factory head unit into low-level RCA signals for aftermarket amplifiers. It features a Load Matching Circuit (LMC) to ensure compatibility with various OEM systems.
- Mounting: Choose a secure, dry location for the LC5iPRO, away from heat sources and moisture. Ensure adequate ventilation.
- Power Connections: Connect the +12V terminal to a constant +12V source (fused, 2A recommended), the Ground terminal to a solid chassis ground, and the Rmt In terminal to the amplifier's remote turn-on output or a switched +12V source. The Rmt Out terminal provides a remote turn-on signal for your amplifiers.
- Input Connections: Connect the factory speaker wires to the Channel 1 Inputs and Channel 2 Inputs terminals. The LC5iPRO supports up to 5 channels of input.
- Load Select: Adjust the Load Select switches (20 Ohm, 60 Ohm, 20 kOhm) for each input channel to match the impedance requirements of your factory head unit. This ensures proper signal detection and prevents error codes.
- Signal Bus / Sum Bus: Use the Signal Bus or Sum Bus switches to combine input channels if necessary (e.g., summing front and rear signals for a subwoofer output).
- Ground Isolation: Set the Ground Isolation switch (GND, ISO, 200 Ohm) to eliminate ground loop noise. Start with GND, then try ISO or 200 Ohm if noise persists.
- Output Connections: Connect the LC5iPRO's Channel 1, Channel 2, and Channel 3 Outputs to your aftermarket amplifier's RCA inputs using the provided RCA interconnects.
- ACR-1 Level Control: Connect the ACR-1 remote level control to the LC5iPRO for convenient bass level adjustment from the driver's seat.

4.2 Stinger SS600XS Wiring Kit Installation
The Stinger SS600XS kit provides the necessary power, ground, and signal cables for your amplifier installation.
- Power Wire: Run the 17FT Translucent Blue Power Wire from the vehicle's battery (through the firewall, using a grommet to protect the wire) to the AGU Fuseholder. Connect the other end of the fuse holder to your amplifier's +12V input. Ensure the fuse is installed only after all connections are made.
- Ground Wire: Connect the 3FT Translucent Silver Ground Wire from your amplifier's ground terminal to a clean, bare metal chassis ground point in the vehicle. Ensure a solid connection for optimal performance.
- RCA Interconnects: Connect the 17FT Translucent Blue Twisted Pair RCA Interconnects from the LC5iPRO's outputs to your amplifier's inputs. Route these cables away from power wires to minimize noise.
- Remote Turn-On Wire: Connect the remote turn-on wire from the LC5iPRO's Rmt Out terminal to your amplifier's remote turn-on input.
- Speaker Wire: Use the 20FT Translucent Speaker Wire to connect your amplifier's speaker outputs to your speakers. Ensure correct polarity.

5. Operating Instructions
5.1 LC5iPRO Controls
The LC5iPRO offers several controls to optimize your audio system's performance.
- Level Controls: Each output channel (Channel 1, Channel 2, Channel 3) has a dedicated level control. Adjust these to match the input sensitivity of your aftermarket amplifier. The 'Max' indicator LED will illuminate when the output signal is approaching clipping, indicating the maximum clean output level.
- AccuBass: This feature restores bass response that is often rolled off by factory audio systems at higher volumes. The AccuBass section has two controls:
- Level: Adjusts the amount of bass restoration.
- Threshold: Sets the point at which AccuBass begins to engage.
- Trigger Mode: This switch determines how the LC5iPRO turns on and off.
- Rmt In: The unit turns on when a +12V signal is applied to the Rmt In terminal.
- GTO (Great Turn-On): The unit senses a DC offset on the input signal from the factory head unit and turns on automatically.
- Audio: The unit senses audio signal on the inputs and turns on automatically.

5.2 Initial System Turn-On and Adjustment
- After all connections are made, reconnect the vehicle's battery.
- Turn on your vehicle's audio system. The LC5iPRO's power indicator LED should illuminate.
- Set all LC5iPRO output level controls to their minimum position.
- Play a familiar piece of music with a wide dynamic range.
- Slowly increase the LC5iPRO's output level controls until the 'Max' indicator LED just begins to flicker, then back off slightly. This sets the maximum clean output.
- Adjust your amplifier's input gain controls according to its manual.
- Fine-tune the AccuBass Level and Threshold controls to achieve desired bass response.
- Use the ACR-1 remote level control for convenient bass adjustments.
6. Maintenance
- Periodically inspect all wiring connections for tightness and corrosion.
- Keep the LC5iPRO and wiring components clean and free of dust and debris. Use a soft, dry cloth for cleaning.
- Ensure the fuse in the AGU Fuseholder is intact and of the correct rating. Replace only with a fuse of the same type and rating.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to LC5iPRO | Blown fuse; incorrect power/ground connection; Rmt In not receiving signal. | Check LC5iPRO fuse (2A); verify +12V and ground connections; check Rmt In signal or try different Trigger Mode. |
| No audio output | Incorrect input/output connections; LC5iPRO level controls too low; amplifier not powered or in protect mode. | Verify all RCA and speaker wire connections; increase LC5iPRO output levels; check amplifier power and status. |
| Distorted audio | LC5iPRO output levels too high (clipping); amplifier gain too high; AccuBass settings incorrect. | Reduce LC5iPRO output levels until 'Max' LED stops flickering; adjust amplifier gain; fine-tune AccuBass Level and Threshold. |
| Engine noise/hiss | Ground loop; RCA cables routed too close to power wires. | Adjust Ground Isolation switch (GND, ISO, 200 Ohm); re-route RCA cables away from power wires. |
| Factory head unit error codes | Incorrect Load Select setting on LC5iPRO. | Adjust Load Select switches to match OEM impedance (e.g., 20 Ohm, 60 Ohm, 20 kOhm). |
