2.2 Connexions d'alimentació
Connecteu el amplifier to the vehicle's electrical system using appropriate gauge wiring. The JX360/2 features captured power and speaker connectors for secure and simplified wiring.
- Connecteu el +12VDC terminal to the positive terminal of the vehicle's battery via a fuse or circuit breaker (not included). The fuse/breaker should be located within 18 inches (45 cm) of the battery.
- Connecteu el Terra terminal to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid electrical connection.
- Connecteu el Remot terminal to the remote turn-on output of your head unit. This wire signals the amplificador per encendre i apagar amb la unitat principal.

2.3 Connexions d'entrada d'àudio
The JX360/2 supports both high-level (speaker level) and low-level (RCA) inputs.
- Entrades de baix nivell (RCA): Connecteu els cables RCA del preamplificador de la unitat principalamp sortides al amplifier's "Low-Level Inputs."
- Entrades d'alt nivell: If your head unit does not have RCA outputs, connect the speaker wires directly to the amplifier's "Hi-Level Inputs" using the provided connector.
2.4 Connexions de sortida d'altaveus
Connecteu els vostres altaveus al amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for each speaker.
- For 2-channel stereo operation, connect one speaker to the Left (+) and Left (-) terminals, and another speaker to the Right (+) and Right (-) terminals.
- For bridged mono operation (e.g., for a subwoofer), connect the speaker to the "Bridged" terminals as indicated on the amplifier. The JX360/2 can deliver 360W into a 4-ohm load when bridged.

3. Funcionament del Ampmés viu
3.1 Engegada inicial
After all connections are made, turn on your head unit. The amplifier should power on automatically via the remote turn-on wire. Observe the power indicator light on the ampmés viu.
3.2 Adjusting Input Sensitivity (Gain)
The "Input Sens." control matches the ampsensibilitat d'entrada del lifter al volum de sortidatage of your head unit. Start with the control at its minimum setting. Play a dynamic piece of music through your system. Slowly increase the "Input Sens." control until you hear distortion, then back it off slightly. This ensures maximum clean output from the ampmés viu.
3.3 Filter Settings
The JX360/2 features a 12 dB/octave variable filter, adjustable from 50 Hz to 500 Hz. This allows you to optimize the frequency response for your speakers.
- HP (High-Pass): Use this setting to block low frequencies from reaching your full-range speakers, preventing distortion and improving clarity.
- LP (Low-Pass): Use this setting when driving a subwoofer, allowing only low frequencies to pass through.
- Complet: Disables the filter, allowing the full frequency range to pass.
Adjust the "Filter Freq." knob to select the desired crossover point.
3.4 Pass-Through Preamp Sortides
El amplifier includes pass-through preamp outputs, allowing you to send the audio signal to another amplifier in your system without requiring additional RCA outputs from your head unit.
4. Manteniment
The JL AUDIO JX360/2 amplifier is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Neteja: Netegeu periòdicament el ampl'exterior del purificador amb un drap suau i sec. No utilitzeu productes químics agressius ni netejadors abrasius.
- Ventilació: Assegureu-vos que el amplifier's heatsink fins are not obstructed. Adequate airflow is essential for proper cooling.
- Connexions: Occasionally check all power, ground, and speaker connections to ensure they remain secure. Loose connections can lead to performance issues or damage.
5. Solució De Problemes
Si teniu problemes amb el vostre amplifier, consulteu els següents problemes i solucions habituals:
5.1 No Power / Amplifier Does Not Turn On
- Check the main fuse or circuit breaker on the +12VDC power line.
- Verify the ground connection is secure and making good contact with the chassis.
- Ensure the remote turn-on wire is connected and receiving +12V from the head unit when it is on.
- Check all power and ground connections at the ampterminals de lifier.
5.2 Sense sortida d'àudio
- Confirmeu el amplifier is powered on (power indicator light is illuminated).
- Check all RCA or high-level input connections from the head unit to the ampmés viu.
- Verify speaker wire connections at both the amplifier and the speakers. Ensure correct polarity.
- Comproveu el volum i la selecció de font de la unitat principal.
- Ensure the "Input Sens." control is not set to minimum.
5.3 Distortion or Poor Sound Quality
- Adjust the "Input Sens." (gain) control. If set too high, it can cause distortion.
- Check speaker impedance. Ensure it is within the amplifier's recommended range (2 ohms stereo, 4 ohms bridged).
- Verify filter settings (HP/LP/Full) are appropriate for your speakers.
- Inspect speaker wires for shorts or frayed strands.
- Ensure adequate power supply to the amplificador. Voltage drops can cause distortion.
5.4 Amplifier Overheats (Protection Mode)
- Assegureu-vos el amplifier has sufficient ventilation. Clear any obstructions around the heatsink.
- Check speaker impedance. Running speakers with too low an impedance can cause overheating.
- Reduce the "Input Sens." (gain) setting.
- Verify the power and ground connections are secure and of adequate gauge.
- Permet el amplifier to cool down. If the issue persists, consult a professional.
