Custom Subwoofer Box Grille Top Blueprint - 1994 Ford Bronco Audio Build

This document is a text-free CAD blueprint drawing uploaded to a 1994 Ford Bronco gallery as part of a custom car-audio build set (filename: 'speaker box with grill top.jpg'). It depicts a top (or face) view of a rectangular subwoofer/speaker enclosure fitted with a perforated metal-style grille. The grille surface is rendered as a dense field of small circles in an offset honeycomb pattern, divided into several panels by vertical support strips, likely corresponding to the 'Grill support frame' drawing in the same album. Faint large circular outlines visible through the perforation pattern indicate the mounting positions of two large speaker drivers (consistent with the companion file '12-Single-Ported.jpg', suggesting 12-inch subwoofers). Two small rectangular tabs extend from the lower edge, possibly mounting feet or brackets. The drawing contains no dimensions, tolerances, materials, part numbers, wiring information, or any other text. A reader can learn the general layout and appearance of the grille-covered speaker box design but not its measurements; those presumably appear on other pages of the multi-page set such as 'sub box cut sheet.jpg'. Vehicle applicability cannot be confirmed or contradicted from the drawing itself.
