Run 16/2 or 14/2 to stereo zones and 14/4 for flexible distributed audio. For theaters, prewire 5.1.2, 7.1.4, or higher with back boxes where necessary and blocking for heavy in‑walls. Coordinate speaker grilles with paint schedules, and respect symmetrical placement around architectural features. Add subwoofer coax and power at multiple positions to tame room modes without intrusive cable runs later.

Place backing behind TVs and projectors, and include in‑wall power with a listed kit. Pull dual Cat6A to each display for network, control, and HDMI‑over‑ethernet extenders, plus an empty conduit for unforeseen needs. Stub conduits to accessible cavities, avoiding tight bends. Mark centerlines and final heights on walls to match furniture proportions, keeping cable exits hidden behind sleek mounts.

Choose a closet or mechanical room near cable home runs but away from bedrooms. Provide supply and return airflow, thermostatic fan control, and service clearance front and rear. Isolate vibration with proper rack feet and consider acoustic treatments if the space shares a wall with quiet areas. Leave 30% rack space empty on day one to welcome future sources and switching.
