3.1. Deskargatzea
Kendu arretaz ampAtera salbatzailea bere ontzitik. Egiaztatu osagai guztiak daudela:
- Zapco Z-150.2 SP Ampbiziagoa
- Erabiltzailearen eskuliburua (dokumentu hau)
- Muntatzeko hardwarea (barne badago)
- Dash mount remote gain control (available separately or included depending on package)
3.2. Muntaketa Ampbiziagoa
Choose a mounting location that provides adequate ventilation and protection from moisture. Common locations include under a seat, in the trunk, or behind a panel.
- Ensure the mounting surface is solid and secure.
- Allow at least 2-3 inches of clearance around the amplifier for proper heat dissipation, especially around the cooling fins and fan vents.
- Saihestu muntatzea amplifier upside down, as this can impede cooling.
- Use the provided mounting hardware to secure the ampbizitzailea irmoki.
3.3. Kableatu konexioak
Refer to the diagrams below for proper wiring connections. Ensure all connections are tight and insulated to prevent short circuits.

3.3.1. Power Input (Figure 2)
- +12V (Energia): Connect a heavy gauge wire (e.g., 4 AWG or 8 AWG depending on total system power) directly from the vehicle's positive battery terminal. Install an inline fuse (not supplied) within 18 inches of the battery.
- GND (lurra): Connect a heavy gauge wire of the same size as the +12V wire to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- REM (Urrutiko Piztapena): Connect a thin gauge wire (e.g., 18 AWG) from the remote turn-on output of your head unit. This wire turns the ampLififier zure estereoarekin piztu eta itzali.
3.3.2. Speaker Output (Figure 2)
Connect your speakers to the CH1 and CH2 terminals. Observe correct polarity (+ to + and - to -).
- Modu estereo: Connect one speaker to CH1 (+/-) and another to CH2 (+/-). The amplifier supports 2-ohm stereo loads per channel.
- Zubia modua: For higher power output to a single speaker (e.g., a subwoofer), bridge the channels. Connect the speaker's positive terminal to CH1+ and the negative terminal to CH2-. Ensure the speaker impedance is suitable for bridged operation (typically 4 ohms minimum). The amplifier supports 4-ohm bridged loads.

- RCA Outputs (OUTPUT): These provide a pass-through signal for connecting additional ampigogailuak.
3.3.4. Fuses (Figure 2)
The amplifier is equipped with two 30A blade-type fuses. These fuses protect the amplifier from electrical overloads. If a fuse blows, replace it only with a fuse of the same rating (30A). Never use a higher rated fuse, as this can cause severe damage to the amplifikatzailea edo ibilgailua.
4. Funtzionamendua Ampbiziagoa
Behin instalatuta, amplifier's performance can be optimized using the controls on the front panel (refer to Figure 3).
4.1. Controls and Adjustments (Figure 3)
- GAIN (Input Sensitivity): Kontrol hau bat dator ampLikidatzailearen sarrera-sentsibilitatea irteerako bolumenarekikotage of your head unit. Start with the gain set to minimum (fully counter-clockwise). Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear slight distortion, then back off slightly.
- X-OVER Scale: This switch selects the frequency range for the High-Pass Filter (HPF) and Low-Pass Filter (LPF). Options are typically 15Hz-500Hz or 150Hz-5000Hz (with x10 multiplier).
- HPF (Pasa handiko iragazkia): This filter allows frequencies above the set point to pass through to the speakers. Use this for full-range speakers or tweeters to prevent low frequencies from damaging them.
- LPF (Pase Baxuko Iragazkia): This filter allows frequencies below the set point to pass through. Use this for subwoofers to prevent high frequencies from playing.
- OSOA: Bypasses both HPF and LPF, allowing the full frequency range to pass through.
- MULTIPLIER (x1 / x10): Extends the range of the HPF/LPF frequency controls. When set to x10, the frequency knob's value is multiplied by 10.
- BASS BOST: Provides an adjustable boost to bass frequencies (0-12dB). Use sparingly to avoid distortion and speaker damage.
- IRAGAZKI SUBSONIKOA: Filters out extremely low frequencies that are inaudible and can waste amplifier power or damage subwoofers. Typically set below the LPF frequency for subwoofers.
- URRUTIKOA: Port for connecting an optional dash-mount remote gain control.
