- Agbara Ibẹrẹ: Reconnect the vehicle's battery. Turn on your head unit. The amplifier yẹ kí ó tan, tí a fi àmì LED hàn.
- Eto Ere: Bẹrẹ pẹlu awọn amplifier's gain control set to minimum. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's gain until you hear distortion, then back off slightly. The gain control is not a volume control; it matches the amplifier's input sensitivity to the head unit's output.
- Awọn eto adakoja: Ṣatunṣe awọn amplifier's crossover filters (if available) according to your speaker type and system configuration. For subwoofers, use a Low-Pass Filter (LPF). For full-range speakers, use a High-Pass Filter (HPF).
