You're building your dream home. The theater room is framed out, the audio zones are planned, and you're picking finishes. But there's a two-week window during every new build where you either get the AV wiring right or spend three times as much fixing it after move-in. That window closes the day drywall goes up.
Once those walls are finished, your options shrink and your costs jump. We're not trying to upsell you on extras here — we just don't want you tearing open brand new walls six months after you move in.
Speaker Wire Has to Go In Before Drywall — Period
If you want in-wall or in-ceiling speakers — and about 80 percent of homeowners do, because nobody wants speakers sitting on shelves taking up space — the wire has to be in place before drywall goes up. That means running speaker cable from every speaker location back to a central equipment area where your amplifier or AV receiver will live.
And this isn't just about the main theater room. Planning whole-home audio in your kitchen, living room, patio, master bedroom? Every single speaker location needs wire run to it during framing. Once the drywall crew finishes, your chance to run wire through open walls is gone.
The newest trend is fully hidden speakers — the speaker sits behind the drywall with no visible grille or mesh. You literally can't tell where the speakers are. Personally, I still like the look of a visible mesh grille, but I'll admit the fully hidden setup sounds incredible when it's done right. It does require pre-construction planning though, because the speaker itself becomes part of the wall assembly.
Home Theater Circuits: Why Your Theater Needs Its Own Breaker
Here's something most builders won't think about unless someone tells them: your home theater audio system and your video display need to be on separate electrical circuits. For a serious home theater, this isn't optional — it's the difference between a system that works reliably and one that trips the breaker during the best part of the movie.
A home theater with a quality amplifier and subwoofers pulls serious wattage. If the screen — especially an LED video wall — is sharing that same circuit, the combined draw pushes a standard 20-amp breaker to its limit. Our own system at home hits 65 to 70 dB before the breaker starts hunting. That's with a dedicated circuit. Imagine sharing one with your LED wall and your overhead lights.
During framing is when your electrician runs dedicated circuits from the panel to your theater space. One circuit for audio equipment, one for the display, and ideally a third for lighting control. Costs almost nothing during construction. Becomes a major project after the fact.
LED Video Wall Backing and Support Structure
Want that clean, flush-mounted look where the screen looks like it's part of the wall? That frame has to go in during framing. Even if an LED video wall is a "maybe someday," the backing structure needs to be there before drywall. You need a recessed frame built into the wall cavity with all the wiring already in place: power, HDMI, and network cable.
The alternative is surface-mounting after construction. It works, but it never looks as clean. You'll see the mounting hardware, cables need to be managed on the surface, and the wall sticks out instead of sitting flush. For a custom home where aesthetics matter, pre-construction mounting is the way to go.
Network Infrastructure: More Important Than You Think
Every smart home system — audio, video, security cameras, lighting control — runs on your network. Running Cat6 ethernet to key locations during framing costs a fraction of what it costs to retrofit later. At minimum, you want hardwired network drops in your theater room, your equipment closet, and anywhere you're putting a wireless access point.
And if your home is over 2,000 square feet, a single router isn't gonna cut it. Plan for wired access point locations during framing so you get reliable coverage everywhere — especially in rooms with in-wall speakers controlled by a phone app. A whole-home audio system that drops out because your Wi-Fi can't reach the back patio defeats the entire purpose.
What If You Missed the Pre-Wire Window?
It happens. You were focused on countertops and cabinet hardware and the AV wiring slipped through the cracks. Not the end of the world, but your options change.
Single story with attic access? We can still run wire for whole-home audio and in-ceiling speakers without tearing into walls. Second floor of a two-story with attic above? Same deal — doable. First floor of a two-story with no crawl space? That's where it gets tricky. At that point you're either opening up drywall — patching and repainting — or going wireless. Wireless works, but it's more expensive per speaker and less reliable than hardwired. Either way, it costs more than if you'd done it during framing.
The Pre-Construction Wiring Checklist
Before your builder closes up the walls, make sure these are handled.
Speaker wire run to every in-wall and in-ceiling speaker location, with cables terminated at a central equipment area.
Dedicated electrical circuits for your theater — separate circuits for audio, display, and lighting.
LED video wall recessed frame and backing plate installed if applicable.
Cat6 ethernet run to the theater room, equipment closet, and wireless access point locations.
Conduit or low-voltage pathways for future expansion. Even if you're not wiring everything now, an empty conduit gives you options later. That's the cheapest insurance you'll ever buy on a build.
