This manual provides essential instructions for the installation and use of Hertz Mille Pro Series subwoofers. Before beginning installation, ensure the head unit and all audio devices are turned off to prevent damage. All components must be firmly secured to the vehicle structure. Always wear protective eyewear when using tools.
Enclosure Design
The manual includes ready-to-build designs for both Sealed and Reflex enclosures. Sealed designs provide tight, accurate bass reproduction, while Reflex designs are optimized for high SPL output.
- Sealed Enclosures: Best for tight, accurate bass (20Hz-40Hz range).
- Reflex Enclosures: Best for high SPL (40Hz-80Hz range).
Refer to the specific pages for your model (MP or MPS series) to find the correct panel cut lists, net volumes (Vb), and tuning frequencies (Fb).
Wiring
Wiring diagrams are provided for single and multiple subwoofer configurations. Ensure your amplifier is stable at the final impedance load of your chosen configuration (Series, Parallel, or Mixed). Always use high-quality cables with the correct AWG section.
Mesh Grille Removal and Installation
To remove or rotate the mesh grille:
- Remove the screw using the provided tool.
- Carefully remove the mesh.
- Rotate 90 degrees if needed.
- Re-insert the mesh and screw it back on.
Warning: Pay attention not to damage the surround during this process.
Technical Specifications
The manual contains detailed Thiele & Small parameters and physical dimensions for all MP and MPS models. These specifications are crucial for designing custom enclosures and ensuring amplifier compatibility.

Practical help
Common problems
Distortion or poor sound quality
Verify that the wiring impedance matches your amplifier's capabilities and that the enclosure volume is correct for your specific subwoofer model.
Enclosure does not fit
Ensure you are using the correct enclosure design (Sealed vs Reflex) and dimensions provided for your specific model (MP or MPS series).
Before use
- Turn off the head unit and all audio system devices before installation.
- Wear protective eyewear when using tools.
- Ensure all components are firmly secured to the vehicle structure.
- Use only cables with the proper section (AWG) as indicated.
- Protect cables with rubber grommets when passing through the vehicle chassis.
- Keep components away from water, excessive humidity, dust, or dirt.
Images and diagrams
- Wiring diagrams illustrate how to connect single or multiple subwoofers in series, parallel, or mixed configurations.
- Enclosure design pages provide panel cut lists and assembly layouts for sealed and reflex boxes.
Model compatibility
- Ensure your amplifier is stable at the final impedance load of your subwoofer configuration.
- Use only recommended enclosure volumes for optimal performance.
