4.2 Power and Ground Connections
Connecteu el amplifier to the vessel's electrical system as follows:
- +12V (Alimentació): Connect a heavy-gauge power wire (refer to specifications for recommended gauge) from the positive terminal of the battery to the +12V input on the amplifier. Install an appropriate fuse or circuit breaker near the battery.
- GND (terra): Connect a heavy-gauge ground wire from the GND input on the amplifier to a clean, solid metal point on the vessel's chassis or a dedicated ground bus bar. Ensure a low-resistance connection.
- REM (encesa remota): Connect a remote turn-on wire from your head unit's remote output to the REM input on the amplificador. Aquest cable indica el ampl'activador s'encén quan la unitat principal està activa.

4.3 Connexions d'entrada d'àudio
Connect your audio source (e.g., marine head unit) to the amplifier's RCA input jacks. The M800/8 V2 features 8 channels, allowing for flexible input configurations.
- Entrades RCA: Connect RCA cables from your head unit's pre-outs to the corresponding input channels (CH. 1&2, CH. 3&4, CH. 5&6, CH. 7&8) on the ampmés viu.
- Mode d'entrada: Use the Input Mode switches on the control panel to select between 2-channel, 4-channel, or 8-channel input configurations, depending on your source unit's outputs.
4.4 Connexions de sortida d'altaveus
Connect your marine speakers and subwoofers to the amplifier's speaker output terminals. The M800/8 V2 supports both stereo and bridged configurations.
- Terminals d'altaveus: Connect speaker wires to the appropriate channel outputs (CH. 1-8). Observe correct polarity (+ to + and - to -).
- Mode pont: For higher power output to subwoofers, channels can be bridged. Refer to the markings on the amplifier for correct bridged wiring (e.g., CH. 1&2 Bridged).
4.5 Control Panel Settings
El amplifier's control panel allows for fine-tuning of audio settings:

Figura 4.4: Detallada view of the control panel settings.
- Input Sens (Input Sensitivity/Gain): Adjust this control to match the output voltage of your source unit. Start with the control at minimum and slowly increase until desired volume is achieved without distortion.
- Mode de filtre: Select between OFF (full range), HP (High-Pass), or LP (Low-Pass) for each channel pair.
- HP (High-Pass): Allows frequencies above the set point to pass, typically used for component speakers.
- LP (Low-Pass): Allows frequencies below the set point to pass, typically used for subwoofers.
- Filter Freq (Filter Frequency): Adjust this dial to set the cutoff frequency for the selected filter mode.
- Control de nivell remot: An optional wired remote level control can be connected to the RJ45 port for convenient bass level adjustment from the listening position.
5. Instruccions de funcionament
Once properly installed, operating the M800/8 V2 amplifier és senzill:
- Encès/apagat: El amplifier will automatically turn on when your head unit is powered on (via the remote turn-on wire) and turn off when the head unit is off.
- Reproducció d'àudio: Play audio through your head unit. Adjust the volume on your head unit and fine-tune the amplifier's gain settings for optimal sound quality without distortion.
- Llums indicadores: Observe the status indicator light on the amplifier. A solid green light indicates normal operation. Refer to the troubleshooting section if the light indicates an issue.
6. Manteniment
The JL Audio M800/8 V2 is designed for durability in marine environments, but regular maintenance can extend its lifespan:
- Neteja: Netegeu periòdicament el ampexterior del lifer amb un suau, damp cloth to remove dust and salt residue. Do not use harsh chemicals or abrasive cleaners.
- Connexions: Annually inspect all power, ground, and speaker connections for corrosion or looseness. Clean and re-tighten as necessary.
- Ventilació: Ensure that the cooling fins are free from obstructions to allow proper heat dissipation.
7. Solució De Problemes
Si teniu problemes amb el vostre amplifier, consulteu els següents problemes i solucions habituals:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense alimentació / Ampel lifier no s'encén | Fusible fundit, cable d'alimentació/terra/control remot solt, senyal d'encesa del control remot defectuós. | Check fuse near battery. Verify all power, ground, and remote connections are secure and have proper voltage. Test remote wire for 12V when head unit is on. |
| Sense sortida d'àudio | No input signal, incorrect gain setting, speaker wires disconnected, amplificador en mode de protecció. | Check RCA input connections. Adjust input sensitivity. Verify speaker wire connections. Check amplifier status light for protect mode indication. |
| So distorsionat | Gain set too high, incorrect filter settings, poor ground connection, damaged speakers. | Reduce input sensitivity (gain). Adjust filter settings (HP/LP) appropriately for speakers/subwoofers. Inspect ground connection. Test speakers with another ampvidador si és possible. |
| Ampsobreescalfament del lificador | Insufficient ventilation, impedance too low, prolonged high-volume use. | Assegureu-vos que hi hagi un flux d'aire adequat al voltant de amplifier. Check speaker impedance to ensure it meets amplifier specifications. Reduce volume or allow amplificador per refredar. |
If the problem persists after attempting these solutions, contact JL Audio customer support or a qualified service technician.
