Hertz HMS 10 S2-LD-SW Marine Subwoofer
The HMS 10 S2-LD-SW subwoofers are engineered for high-power, infinite-baffle operation, eliminating the need for a dedicated enclosure. They feature durable polypropylene cones with UV inhibitors, high-density flux ferrite magnets, and integrated RGB LEDs for customizable lighting effects. The white sport grilles are paintable to match your vessel's aesthetics.

4. Configuració i instal·lació
Careful installation is crucial for optimal performance and longevity of your marine audio system.
4.1 AmpMuntatge de lifier
Trieu una ubicació de muntatge seca, ben ventilada i protegida de la llum solar directa i la calor excessiva. Assegureu-vos que hi hagi prou espai al voltant amplifier for air circulation. Secure the amplifier using appropriate fasteners to a solid surface.
4.2 Wiring Connections (HMD1 Ampmés viu)
Refer to Figure 2 for connection points.
- Power (POWER - 12V): Connect the positive (+) terminal to the boat's 12V battery via a fused power cable. Connect the negative (-) terminal to a solid ground point on the boat's chassis or battery negative. Use heavy-gauge wire suitable for the current draw.
- Fuses (FUSE 2x30A): El amplifier is protected by two 30A blade fuses. Ensure these are correctly installed.
- Speaker Out (SPEAKER OUT 1, 2): Connect your subwoofers to these terminals. The HMD1 is a mono amplifier, so both subwoofers should be wired in parallel to achieve a 1-Ohm or 2-Ohm load, depending on the subwoofer impedance. For two 2-Ohm subwoofers, wiring them in parallel will result in a 1-Ohm load.
- SPK IN / REM IN / MUTE: These terminals are for speaker-level inputs and remote turn-on/mute functions.
- PRE IN (RCA): Connect your head unit's RCA pre-out to this input for a low-level signal.
- SENSITIVITY (H, M, L): This switch adjusts the input sensitivity. Set it to match the output level of your head unit.
- ART ON/OFF: Automatic Remote Turn-on. When ON, the amplifier will turn on automatically when it detects an audio signal on the speaker-level inputs. When OFF, a remote turn-on wire is required.
- LINK ON/OFF: Used for linking multiple amplifiers. Refer to advanced wiring diagrams if using this feature.
4.3 Subwoofer Installation (HMS 10 S2-LD-SW)
The HMS 10 S2-LD-SW subwoofers are designed for infinite-baffle applications, meaning they do not require a sealed enclosure. They can be mounted directly into a panel or bulkhead, using the boat's interior volume as the 'enclosure'.
- Lloc de muntatge: Choose a sturdy, flat surface with sufficient depth clearance (refer to specifications for dimensions). Ensure the mounting surface is rigid enough to prevent vibrations.
- Retall: Carefully cut the mounting hole according to the specified diameter.
- Cablejat: Connecteu els terminals del subwoofer a amplifier's speaker outputs. Ensure correct polarity (+ to + and - to -). For two 2-Ohm subwoofers, wire them in parallel to the HMD1 amplifier for a 1-Ohm load.
- RGB LED Wiring: Connect the RGB LED wires to a compatible RGB controller (not included) for customizable lighting effects. Follow the controller's instructions for wiring.
- Instal·lació de la graella: Secure the white sport grille over the subwoofer. The grille can be painted to match your vessel's color scheme.

5. Instruccions de funcionament
5.1 Engegada/apagada
El amplifier will power on when a remote turn-on signal is received (either from the head unit's remote output or via the ART function if enabled). It will power off when this signal is removed.
5.2 Adjusting Sensitivity (Gain)
The SENSITIVITY switch on the HMD1 amplifier allows you to match the amplifier's input level to the output level of your head unit. Start with the switch in the 'L' (Low) position and gradually increase it to 'M' (Medium) or 'H' (High) if needed. Adjust the gain control on the amplifier (if present, not explicitly detailed in provided data) to achieve maximum clean output without distortion. It is recommended to set the head unit volume to about 75% of maximum, then adjust the amplifier gain until the sound is loud and clear without audible distortion. If distortion occurs, reduce the gain.
Control de LED RGB 5.3
The integrated RGB LEDs in the HMS 10 S2-LD-SW subwoofers require an external RGB controller (not supplied) for operation. Connect the subwoofer's RGB wiring to the controller according to the controller's instructions. This allows for customization of color and lighting effects.
6. Manteniment
Regular maintenance ensures the longevity and optimal performance of your marine audio system.
- Neteja: Netegeu periòdicament el amplifier and subwoofers with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners. Ensure all components are dry before operation.
- Inspecció de connexió: Annually inspect all power, ground, speaker, and signal connections for corrosion, looseness, or damage. Tighten any loose connections and clean any corrosion.
- Substitució de fusibles: Si el amplifier fails to power on, check the 30A fuses. Replace blown fuses only with fuses of the same type and rating.
- Controls ambientals: Assegureu-vos el amplifier's mounting area remains well-ventilated and free from obstructions. Verify that subwoofers are securely mounted and grilles are intact.
