The Hertz MPG250-3 is an optional protective grille for compatible 10-inch Mille PRO subwoofers. It provides a finished appearance while helping shield the subwoofer from incidental contact inside a vehicle installation. This is a passive accessory, not a subwoofer or an amplified audio component.
It is intended for builders who want to retain visible subwoofer installation while adding front-side protection. The grille is suited to trunk, cargo-area, and custom enclosure applications where the woofer may be exposed. Its 250 mm format matches the size class of compatible Mille PRO subwoofers.
Because it is a grille rather than a sound-producing component, it has no power rating, impedance, or wiring requirement. Its role is physical protection and presentation within the system. The open grille format allows it to be used in front of the compatible subwoofer without requiring a separate electrical connection.
The MPG250-3 uses die-cast aluminum construction and carries an aluminum Hertz logo with a diamond-cut finish. These details give the accessory a coordinated appearance with Mille PRO equipment while providing a rigid protective structure. The product is specified as an optional Mille PRO subwoofer grille.
Use the MPG250-3 as part of a Mille PRO 10-inch subwoofer upgrade or enclosure finishing plan. Confirm the subwoofer model and available mounting clearance before ordering, particularly when using a custom enclosure. Hertz documentation identifies this grille as the optional grille for MP 250 D2.3 and MP 250 D4.3 subwoofers.
Key Features
- 10-Inch Format: Designed for the 250 mm subwoofer size class.
- Mille PRO Accessory: Coordinates with Hertz Mille PRO subwoofer installations.
- Die-Cast Aluminum: Provides a rigid, protective grille structure.
- Diamond-Cut Logo: Features an aluminum Hertz logo detail.
- Optional Grille: Adds protection to compatible subwoofer installations.
- No Wiring Needed: Installs as a passive physical accessory.
Design & Installation
The MPG250-3 is built as a 250 mm grille with die-cast aluminum construction and an aluminum Hertz badge finished with a diamond-cut treatment. It is designed as an exterior protective accessory for a Mille PRO subwoofer installation. The grille does not add amplification, electrical load, or signal-processing functions.
Install it only after confirming fitment with the compatible MP 250 D2.3 or MP 250 D4.3 subwoofer and the enclosure or mounting surface being used. Check that the grille will clear the subwoofer surround and any enclosure trim before fastening it in place. No speaker wiring is required for the grille itself; package contents and mounting hardware should be verified with the selling dealer before installation.
