Vehicle Audio Layout And Seat-Coverage Workflow

Use one sheet per architecture and preset revision. Keep the source mode, seat goal, physical layout, channel map, acoustic result, protection, and recovery behavior tied to the same version.

Stop And Redesign If

☐ a speaker has no documented seat, source, coverage, imaging, or vehicle-function role
☐ a candidate location conflicts with restraint, glass, visibility, water, crash, or service requirements
☐ the channel count, converters, amplifiers, power, or cooling cannot support the architecture
☐ a center or rear contribution improves one trace while collapsing the stage or another seat
☐ an average result hides an unacceptable worst-seat condition
☐ an immersive logo or speaker count is the only proof of decode and rendering
☐ final trim, calls, prompts, alerts, key cycles, failure, or recovery states have not been tested
