3.2 Quvvat ulanishlari
Quvvat, yerga ulash va masofadan boshqarish simlarini ulang amplifier's power input terminal block.
- +12V (Quvvat): 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 (er): 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. Ishlash Amphayotiyroq
Once all connections are made and verified, you can power on your system and adjust the ampko'taruvchi sozlamalari.
4.1 Initial Power-Up and Gain Adjustment
- Bosh qurilmangizni yoqing. The amplifier should power on (indicated by the power LED).
- ni o'rnating amplifier's GAIN control to its minimum position.
- Play a familiar music track with a strong bass presence at about 75% of your head unit's maximum volume.
- GAIN boshqaruvini asta-sekin oshiring amplifier until you hear distortion, then back it off slightly. The POWER/CLIP/PROTECT indicator can assist in setting the gain without clipping.

4.2 Crossover and Bass Boost Adjustments
- LPF (past o'tish filtri): 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 KO'CHIRISH: 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.
