- +12V (ພະລັງງານ): Connect a heavy-gauge power cable (e.g., 4 AWG or larger for 1500W RMS) directly from the positive terminal of the vehicle's battery. Install an appropriate fuse (not included) within 18 inches of the battery.
- REM IN (Remote Turn-On): Connect a 18-gauge wire from the remote turn-on output of your head unit or other switched 12V source.
- GND (ດິນ): Connect a heavy-gauge ground cable (same gauge as power) to a clean, unpainted metal surface of the vehicle's chassis. Ensure a solid electrical connection.

4.2 Crossover and Bass Boost Adjustments
- LPF (ຕົວກອງຕ່ຳ): Adjust this control to filter out high frequencies from your subwoofer. A common starting point is 80-100 Hz.
- SUBSONIC Filter: This filter removes extremely low frequencies that are below the audible range and can cause damage to your subwoofer. Set it slightly below your subwoofer's port tuning frequency or around 20-30 Hz.
- bass boost: Use this control sparingly to enhance bass output. Excessive bass boost can lead to distortion and potential speaker damage. Start at 0dB and increase gradually if desired.
