- Netefatsa hore moea o phalla hantle ho potoloha amplifier's heatsink fins for proper cooling.
- Thaba ea amplifier securely to a solid surface using appropriate hardware.
4.2. Khokelo ea Matla
- Power Cable (B+): Run a heavy-gauge power cable directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install an in-line fuse holder with an appropriate fuse (refer to specifications) within 18 inches (45 cm) of the battery.
- Ground Cable (GND): Connect a heavy-gauge ground cable from the amplifier's GND terminal to a clean, unpainted metal point on the vehicle chassis. The ground cable should be as short as possible, ideally less than 3 feet (1 meter).
- Remote Turn-On Cable (REM): Connect a smaller gauge wire from the amplifier's REM terminal to the remote turn-on output of your head unit. This signal turns the amplifier on and off with your car's audio system.
4.3. Kenyeletso ya Letshwao
- Connect RCA cables from your head unit's pre-out outputs to the ampli-jacks tsa lifier tsa RCA.
- Ensure proper channel matching (Left to Left, Right to Right).
4.4. Puo ea Sebui
- Hokela libui tsa hau ho amplifier's speaker output terminals. Observe correct polarity (+ to + and - to -).
- Ensure the speaker impedance matches the amplifier's recommended load.
5. Litaelo tsa Ts'ebetso
Hang ha amplifier is correctly installed, follow these steps for initial setup and operation:
- Matla a Pele: Reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on, indicated by an LED indicator.
- Gain Setting: Qala ka ho 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 ampkutlo ea lifier ho sephetho sa yuniti ea hlooho.
- Litlhophiso tsa Crossover: Fetola 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).
- Choriso: Make small adjustments to the gain and crossover settings to achieve balanced and clear sound.
