Wiring Diagram
Refer to the diagram below for proper wiring connections. Ensure all connections are secure and correctly polarized.
Figure 2: SKE2LOC Wiring Diagram showing speaker inputs, power connections, and RCA outputs to amplifiers.
Connection Steps
- Power Connection: Connect the +12V terminal to a constant 12V power source (e.g., vehicle battery). Connect the GND terminal to a solid chassis ground point.
- Remote Turn-On:
- If using DC Offset Signal Sense or Audio Sense, the SKE2LOC will generate a remote output signal (REM OUT) for your amplifier. Connect this to your amplifier's remote input.
- If using a dedicated 12V remote turn-on wire from your head unit, connect it to the REM IN terminal.
- Speaker Inputs: Connect the high-level speaker outputs from your factory head unit or amplifier to the SKE2LOC's Speaker Inputs (L+, L-, R+, R-).
- RCA Outputs: Connect the Main Output RCA cables to your full-range amplifier's input. Connect the Bass Output RCA cables to your subwoofer amplifier's input.
- Remote Level Control: Plug the remote level control cable into the "Rmt Out" port on the SKE2LOC and mount the knob in an accessible location.

Operating the SKE2LOC
Adjustable Controls
The SKE2LOC features several adjustable controls to optimize audio performance:
- Threshold: Adjusts the sensitivity for the DC Offset Signal Sense turn-on mode.
- Main Output Level: Controls the output level for the main RCA outputs.
- Bass Output Level: Controls the output level for the bass RCA outputs.
- Remote Level Control: Provides convenient adjustment of the bass output level from the driver's seat.

Setting Turn-On Mode
Use the "Trigger Mode" switch to select how the SKE2LOC turns on:
- REM IN: The unit turns on when a 12V signal is applied to the REM IN terminal.
- DC: The unit senses a DC offset on the speaker inputs to turn on. Adjust the Threshold knob for optimal performance.
- Audio: The unit senses an audio signal on the speaker inputs to turn on.
Ground Isolation
The "Ground Isolation" switch helps eliminate ground loop noise:
- GND: Direct ground connection.
- ISO: Isolated ground connection.
- 200Ω: Ground connection through a 200 Ohm resistor.
Experiment with these settings if you experience noise in your audio system.
Load Select
The "Load Select" switch adjusts the input impedance for compatibility with various factory head units:
- 20Ω: 20 Ohm load.
- 60Ω: 60 Ohm load.
- 20kΩ: 20 Kilo-Ohm load.
Select the setting that provides the cleanest signal without distortion.
Maintenance
The Skar Audio SKE2LOC requires minimal maintenance. Keep the unit clean and free from dust and debris. Do not expose the unit to water or excessive moisture. Periodically check all wiring connections to ensure they remain secure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output. | No power to SKE2LOC; incorrect input/output connections; incorrect turn-on mode. | Check power and ground connections. Verify speaker input and RCA output connections. Adjust "Trigger Mode" switch. |
| Distorted audio. | Input signal too high; output levels set too high; incorrect "Load Select" setting. | Reduce input signal from head unit. Lower Main Output Level and Bass Output Level. Adjust "Load Select" switch. |
| Engine noise/whine. | Ground loop interference. | Adjust "Ground Isolation" switch (GND, ISO, 200Ω) to find the setting that eliminates noise. Ensure proper grounding. |
| Unit does not turn on. | No remote signal; incorrect "Trigger Mode" setting. | Check remote wire connection. Ensure "Trigger Mode" is set appropriately (REM IN, DC, or Audio) and Threshold is adjusted if using DC. |
