Persediaan dan Pemasangan
Proper installation is crucial for optimal performance and safety. It is recommended to have this amplifier installed by a professional car audio technician.
1. Lokasi Pemasangan
- Pilih lokasi yang kering, mempunyai pengudaraan yang baik, jauh daripada cahaya matahari langsung dan sumber haba.
- Ensure sufficient airflow around the ampheatsink lifier.
- Mount securely to prevent movement during vehicle operation.
2. Sambungan Pendawaian
Always disconnect the vehicle's battery before making any power connections.
- Kuasa (BATT +12V): Connect to the positive terminal of the vehicle's battery using a fuse or circuit breaker within 18 inches of the battery. Use appropriate gauge wire (e.g., 8-gauge or 4-gauge depending on total system power).
- Tanah (GND): Connect to a clean, solid metal point on the vehicle's chassis, ensuring good electrical contact. The ground wire should be the same gauge as the power wire and as short as possible.
- Penghidupan Jauh (REM): Connect to the remote turn-on lead from your head unit or other switched 12V source.
- RCA Inputs (AMP1, AMP2): Connect to the RCA outputs of your head unit.
- Keluaran Pembesar suara: Connect your speakers to the appropriate terminals. Observe correct polarity (+/-). For bridged mode, refer to the amplifier's specific bridging instructions (typically marked on the amplebih hidup).

1. Dapatkan Pelarasan
- Set your head unit volume to about 75% of maximum.
- Perlahan-lahan tingkatkan amplifier's GAIN control until you hear slight distortion, then back off slightly.
- Kawalan gandaan sepadan dengan amplifier's input sensitivity to the head unit's output. It is not a volume control.
2. Crossover (X-OVER)
- The CXA300.4 features a variable crossover (50-200Hz).
- Set to "HI" for high-pass filtering (for full-range speakers, blocking low frequencies).
- Set to "LO" for low-pass filtering (for subwoofers, blocking high frequencies).
- Adjust the frequency knob to suit your speakers and desired sound.
3. Peningkatan Bass
- The Bass Boost control (0-12dB) allows you to increase the output at 40Hz.
- Use sparingly to avoid distortion and potential speaker damage.
4. Fader
- If your head unit has a fader control, set the amplifier's FADER switch to "ON". If not, set to "OFF".
