The Ground Zero GZIA 135.4 amplifier features a comprehensive control panel and robust connection terminals for optimal audio system integration.
Aquesta imatge mostra dos views of the Ground Zero GZIA 135.4 amplifier. The top view shows the control panel with gain, crossover (HPF/LPF), and bass boost adjustments for channels 1/2 and 3/4, along with RCA inputs and high-level inputs. The bottom view illustrates the power (GND, REM, +12V) and speaker output terminals (CH1-CH4), including bridging options, and two 30A fuses.
This image shows an optional remote bass level control knob, typically used to adjust the subwoofer output level from the driver's seat. It features 'MIN' and 'MAX' settings.
5. Configuració i instal·lació
Proper installation is crucial for optimal performance and safety. It is highly recommended to have this amplifier installed by a qualified car audio professional.
5.1. Planificació de la Instal·lació
- Choose a mounting location that is dry, well-ventilated, and protected from physical damage. Common locations include under seats, in the trunk, or behind panels.
- Ensure sufficient space for wiring connections and air circulation.
- Plan the routing of power, ground, remote, RCA, and speaker cables to avoid interference and ensure proper lengths.
5.2. Muntatge del Ampmés viu
- Feu servir els cargols de muntatge proporcionats per fixar el ampl'aixellador fermament a una superfície sòlida.
- Ensure the mounting surface can support the amppes del vidador.
5.3. Cablejat d'alimentació
- +12V (Alimentació): Connect a heavy-gauge power cable (e.g., 8 AWG or larger, depending on total system power) directly from the vehicle's positive battery terminal to the +12V terminal on the amplifier. Install an appropriate fuse holder (e.g., 60A for this amplifier) within 18 inches (45 cm) of the battery.
- GND (terra): Connect a heavy-gauge ground cable of the same size as the power cable from the ampel terminal GND del transformador a una superfície metàl·lica neta i sense pintar del xassís del vehicle. Assegureu-vos que la connexió sigui sòlida i de baixa resistència.
- REM (encesa remota): Connecteu un cable de calibre més petit (per exemple, 18 AWG) des del ampel terminal REM del lificador a la sortida d'encesa remota de la unitat principal. Aquest cable indica el amplificador per encendre i apagar amb la unitat principal.
5.4. Entrada de senyal
- Entrades RCA: Connecteu els cables RCA des del pre-emissor de la unitat principalamp sortides al amplifier's CH1/CH2 and CH3/CH4 RCA inputs.
- Entrades d'alt nivell: If your head unit does not have RCA outputs, use the high-level inputs. Connect the speaker wires from your head unit directly to the ampterminals d'entrada d'alt nivell del lificador.
5.5. Cablejat d'altaveus
- Connecteu els vostres altaveus al amplifier's speaker output terminals (CH1, CH2, CH3, CH4).
- Ensure correct polarity (+ to + and - to -) for all speakers.
- For bridged operation (e.g., for a subwoofer), connect the speaker to the designated bridged terminals (e.g., CH3+ and CH4- for a 2-channel bridged output). Refer to the diagram on the amplifier for specific bridging instructions.
- Ensure the speaker impedance matches the amplifier's capabilities (typically 2-4 ohms per channel, or 4-8 ohms bridged).
6. Instruccions de funcionament
Un cop el amplifier is installed and wired correctly, you can proceed with initial setup and adjustments.
6.1. Engegada inicial
- Després de fer totes les connexions, torneu a connectar la bateria del vehicle.
- Engegueu la unitat principal. El amplifier's power indicator should illuminate. If the 'PROTECT' light illuminates, immediately turn off the system and check all wiring for shorts or incorrect connections.
6.2. Ajust de guany
- Estableix el amplifier's GAIN controls to minimum.
- Play a familiar music track at about 75% of your head unit's maximum volume.
- Augmenta lentament el amplifier's GAIN control until you hear distortion, then back it off slightly until the sound is clean. This matches the ampla sensibilitat d'entrada del lificador a la sortida de la unitat principal.
6.3. Configuració del crossover (HPF/LPF)
- HPF (filtre de pas alt): Use this for full-range speakers or tweeters to block low frequencies that they cannot reproduce effectively. Adjust the frequency knob to the desired cutoff point (e.g., 80 Hz for door speakers).
- LPF (filtre de pas baix): Use this for subwoofers to block high frequencies, allowing only bass to pass through. Adjust the frequency knob to the desired cutoff point (e.g., 80-120 Hz for subwoofers).
- PIS: Bypasses the crossover, allowing full-range audio.
6.4. Augment dels baixos
- The BASS BOOST control allows you to enhance low frequencies. Use sparingly to avoid distortion and potential speaker damage. Start at 0dB and increase gradually if desired.
6.5. Remote Bass Control (Optional)
- If equipped, connect the remote bass control to the designated port on the amplificador. Això permet ajustar còmodament el nivell de greus des del seient del conductor.
7. Manteniment
The Ground Zero GZIA 135.4 ampEl lificador requereix un manteniment mínim per garantir un rendiment a llarg termini.
- Neteja: Netegeu periòdicament el ampl'exterior del purificador amb un drap suau i sec. No utilitzeu productes químics agressius ni netejadors abrasius.
- Connexions: Occasionally check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Ventilació: Assegureu-vos que el amplifier's cooling fins are not obstructed by debris or other objects to maintain proper airflow and prevent overheating.

| Amplifier does not turn on (no power light) | Fusible fundit (bateria o ampmés viu) Connexió d'alimentació o de terra fluixa Sense senyal d'encesa remota | Comproveu i substituïu els fusibles si cal. Verifiqueu que totes les connexions d'alimentació i de terra estiguin ben fixades. Check remote wire connection to head unit and ampmés viu. |
| AmpEl lificador s'encén però no hi ha so | Connexions RCA o d'altaveus soltes Incorrect gain or crossover settings Volum de la unitat principal massa baix o silenciat | Check all RCA and speaker connections. Adjust gain and crossover settings. Augmenta el volum de la unitat principal i comprova la funció de silenci. |
| So distorsionat | Guany massa alt Discrepància d'impedància d'altaveu Damaged speakers or wiring | Redueix la configuració del guany. Verify speaker impedance is compatible. Inspect speakers and wiring for damage. |
| Amplifier overheats (PROTECT light on) | Ventilació insuficient Impedància de l'altaveu massa baixa Falla interna | Assegureu-vos ampEl lifer té un flux d'aire adequat. Check speaker impedance. Do not run below minimum recommended impedance. Si el problema persisteix, busqueu servei professional. |
