Hertz MPG165-3 6.5" Mille PRO Speaker Grilles

The Hertz MPG 165.3 PRO is a 165 mm (6.5-inch) protective grille set for compatible Mille PRO speaker installations. It provides a finished, exposed-speaker mounting solution where a factory door panel or existing grille does not protect the driver. This accessory is intended for custom car-audio installations that need a dedicated speaker cover.

Designed around the Mille PRO 165 mm format, the MPG 165.3 PRO is associated with Hertz MPX 165.3 coaxial speakers and Mille PRO woofer applications. Its 6.5-inch format helps it coordinate with compatible Hertz drivers while adding a protective barrier in front of the speaker. Verify available panel clearance and mounting surface dimensions before installation.

This is a passive physical accessory, not a speaker, crossover, or amplifier. It does not require power, signal wiring, or amplifier matching. Its role is to help guard the exposed speaker area from incidental contact while presenting a clean, integrated appearance.

The grille uses a multi-piece design with mesh, frame, and inner-grille elements. Hertz identifies the MPG 165.3 PRO as an optional Mille PRO woofer grille, while the design includes a Hertz logo detail. The construction supports flexible visual treatment for custom door, kick-panel, or display-style installations.

Use the MPG 165.3 PRO when building or refreshing a compatible 165 mm Hertz Mille PRO speaker installation. It is especially useful when speakers are mounted where they remain visible after trim work is completed. The included installation hardware and grille putty support a more complete custom-mounting setup.

Design & Installation

The MPG 165.3 PRO uses black steel mesh, black plastic grille frames, and gray plastic inner grilles in a layered assembly. The grille is described as die-cast aluminum and carries a diamond-cut aluminum Hertz logo. Its listed finish is aluminum, with black and anthracite color elements.

Confirm that the mounting surface accommodates the listed 7.225-inch outer diameter and 1.125-inch mounting height before cutting or drilling. The set includes mounting screws, speed clips, and grille putty; secure all components firmly and check that the grille does not interfere with vehicle trim, window travel, or the speaker cone. It is intended for compatible 165 mm Mille PRO applications, including the MPX 165.3 series.
